    APPEL, Justice.
    In this case, Lee Christensen challenges his conviction of second-
    degree murder following a jury trial. After the trial, Christensen moved for
    a new trial based upon (1) the refusal of the trial court to disqualify a juror
    who allegedly made out-of-court statements regarding the defendant’s
    guilt, (2) prosecutorial misconduct related to allegedly improper testimony
    from two witnesses for the State, and (3) misconduct and bias related to
    extraneous information reaching the jury about a possible riot if a certain
    verdict was not returned. The district court denied the motions for a new
    trial, entered judgment, and sentenced Christensen.                 Christensen
    appealed.
    We transferred the case to the court of appeals. The court of appeals
    reversed, holding Christensen was entitled to a new trial as a result of
    juror misconduct and bias. For the reasons expressed below, we vacate
    the court of appeals decision and affirm the district court judgment.
    I. Factual and Procedural Background.
    A. Introduction. Thomas Bortvit was dating Christensen’s former
    girlfriend. Bortvit and Christensen both lived in Estherville, Iowa. After
    Bortvit was reported missing from work, a community search was
    undertaken in an effort to find him.       As part of its investigation, law
    enforcement wanted to speak with Christensen. After law enforcement
    contacted    the   Christensen    family   about    a   potential     interview,
    Christensen’s mother asked him if he knew Bortvit’s whereabouts, became
    suspicious, and confronted her son. Christensen ultimately told his father
    that he had killed Bortvit.        Christensen provided his father with
    information that led to the discovery of Bortvit’s body in a remote location.
    The State charged Christensen, an Estherville high school student,
    with murder and other lesser included offenses. He pled not guilty. The
    3
    matter proceeded to jury trial in Estherville. The jury found him guilty of
    second-degree murder.
    Christensen filed a posttrial motion attacking the verdict.        He
    claimed the district court erred in refusing to grant a midtrial motion to
    disqualify a juror for cause. He further asserted the verdict was tainted
    because of juror misconduct. He also claimed prosecutorial misconduct
    associated with two witnesses’ testimony required a new trial. The district
    court overruled the motion for a new trial, entered judgment, and
    sentenced Christensen. Christensen appealed.
    B. Selection of the Jury. Before the jury trial began, the parties
    engaged in voir dire of the jury venire. The district court began by asking
    the jurors three questions: (1) whether they had heard about the case from
    the media, (2) whether they had heard about the case from sources besides
    the media, and (3) whether they had formed an opinion about the case.
    Many jurors answered affirmatively to one or more of the questions.
    Counsel for the parties then conducted individual voir dire outside
    the presence of the other venire members. The voir dire process revealed
    that the events surrounding Bortvit’s death were the subject of extensive
    discussion in the Estherville community. Many prospective jurors knew
    members of the Christensen family, the Bortvit family, or both.              In
    addition, many prospective jurors further explained their knowledge about
    the case from the media and from other sources, including various
    Facebook postings.
    A number of jurors believed they could not fairly judge the case
    because they had already formed opinions about the matter. Most often,
    these jurors believed Christensen was guilty. When asked if they could be
    fair in the proceedings, a number said they could not.         Of the sixty
    prospective jurors, the district court disqualified twenty-four for cause.
    4
    During voir dire, the lawyers and prospective jurors recognized the
    emotional character of the case. One prospective juror stated, “I know that
    sentiments run high.” Another remarked, “[I]t is so traumatic that this
    has happened. And whether or not he is guilty, everybody involved has
    been hurt . . . .” A third potential juror stopped going out for coffee because
    “[it was] too disturbing to [the juror] to listen to other people . . .
    disparagingly talk about individuals.” A fourth potential juror when asked
    whether they were well suited to be a juror explained, “I just think I’m
    going to need a tissue a lot.”
    During voir dire of the entire panel, Christensen’s attorney asked
    the jury if anyone had “difficulty with the notion that Lee Christensen
    doesn’t have to prove his innocence, doesn’t have to testify, that you can’t
    hold it against him.” No one responded in the affirmative.
    At the close of jury selection, the district court described how the
    trial would proceed. The district court stated that after the close of the
    State’s case, Christensen could present evidence “if he chooses to.” The
    district court advised the jury, “[Christensen is] not required to [present
    evidence]. As you’ve been told, he’s presumed innocent and the burden
    rests with the state.”
    C. Instructions of the District Court Related to Extraneous
    Communications. After the petit jury had been selected, the district court
    admonished the jury to avoid extraneous communication with anyone
    regarding the trial. Specifically, the district court instructed the jury,
    [Y]ou are not to converse among yourselves or with anyone
    else on any subject connected with this case. . . . If anyone
    should attempt to discuss this case with you or in your
    presence, walk away and do not listen. However, if anyone
    should persist in talking to you or in your presence, report it
    immediately . . . .
    Further, the district court told the jury,
    5
    [Y]ou are admonished not to listen to, view, or read any form
    of media while this case is in progress. . . . This includes . . .
    the full gamut of social media, the internet, cell phone
    communications, Instagram, Twitter. Just for the next few
    days, I need to have you disconnect from that if you’re involved
    at all.
    D. Overview of Evidence Adduced at Christensen’s Trial. On
    June 6, 2015, Bortvit was working in the meat department at a Fareway
    store in Estherville. That afternoon Christensen was seen at the Fareway
    meat counter. His truck was also spotted in the Fareway parking lot.
    Although his family was not going to be home that evening, Christensen
    bought some ground beef, which he put in the freezer when he returned
    home. Bortvit left the Fareway store for his break at about 4:00 p.m.
    Bortvit’s girlfriend, Cayley Fehr, was out of town but exchanged text
    messages with Bortvit during the afternoon. Bortvit told Fehr in a text
    message that he was with Christensen and that Christensen had asked for
    a ride because his truck had broken down. Fehr had dated Christensen
    in the past and knew of the antipathy Bortvit had toward Christensen.
    Later in the day, Fehr received a text message from Bortvit’s phone stating
    that he no longer wanted to date or see Fehr and that they should see
    other people. Fehr subsequently received a text message from Christensen
    stating he had killed Bortvit.
    Christensen arrived home at approximately 5:00 or 5:30 p.m.
    wearing a soiled T-shirt and jeans. He and his sister went downtown for
    a sandwich.    Upon returning home, Christensen watched TV but then
    abruptly went upstairs.
    Late that evening, Bortvit’s friends discovered his car parked and
    locked in a residential area of Estherville. Police and community members
    began to look for Bortvit.
    6
    The next day, Christensen and his mother were driving to Sioux
    Falls to catch a flight to Arizona so that Christensen could attend a cross-
    country sports camp. She learned on Facebook that Bortvit was missing.
    When she told Christensen of the news, he sat quietly. That same day,
    Christensen’s father participated in the search for Bortvit.
    After law enforcement learned that Bortvit had been seen talking to
    Christensen at Fareway, they went to Christensen’s home and told his
    sister they wanted to talk to him.       When Christensen and his mother
    arrived in Arizona, his mother received a text message indicating the police
    wanted to talk to her son.     After a confrontation, Christensen told his
    mother that he and Bortvit had gotten into a fight, that he got scared, and
    that he hit Bortvit with a rock. Thereafter, Christensen called his father
    and told him that he knew where Bortvit’s body was. Christensen’s father
    told police that Christensen had killed Bortvit.    Using directions from
    Christensen, police drove to a place outside of town where Bortvit’s body
    was located in a pasture.
    A search warrant executed at the Christensen home produced a .45
    caliber pistol, ammunition, clothing, and Bortvit’s wallet in Christensen’s
    room. In addition, investigators found bloodstained boots in the lower
    level of the residence.     A search of Christensen’s grandfather’s farm
    produced three .45 caliber cartridge cases and three slugs. The trunk of
    Bortvit’s car contained clothing and other items covered with blood.
    An autopsy revealed that Bortvit died from multiple gunshots and
    that his body exhibited bruising and abrasions. A projectile retrieved from
    Bortvit’s body was traced to the .45 caliber pistol found in Christensen’s
    room. Testing of the pistol revealed Bortvit’s, but not Christensen’s, DNA
    on the grip of the gun. Examiners did not test the gun for blood or other
    biological sources of DNA.
    7
    The jury received the case on June 30, 2016, and deliberated into
    the evening without reaching a verdict. The jury returned to deliberate on
    July 1. That morning, the jurors delivered a note to the district court
    indicating they were “stuck between two verdicts and need[ed] to know
    what [their] options [we]re.”   The district court replied that the jurors
    “should continue to deliberate if [they] believe it would be productive in
    reaching a unanimous verdict.” Later on the afternoon of July 1, the jurors
    returned a verdict of second-degree murder.
    E. Issue of Juror Disqualification. During the trial, a member of
    the news media received a note stating that “there is a jury member telling
    people the young man is guilty and . . . she is sticking to it.” The note also
    identified juror K.B. by a phonetic spelling of the juror’s name.         The
    member of the news media provided the note to the district court, and law
    enforcement conducted an investigation. The investigation revealed an
    employee of a local café heard a patron state that a juror, while at a family
    gathering, “kept on talking about the trial and that Lee Christensen was
    guilty and was going to find him guilty no matter what.”
    Law enforcement prepared an investigative report and the café
    employee signed a written statement describing the events.             These
    documents were admitted into evidence as court exhibits. No testimony
    was obtained from the employee who provided the written statement nor
    from the person in the café who was overheard stating the juror had made
    up her mind on the question of Christensen’s guilt.
    The district court summoned juror K.B. into chambers. The court
    conducted an examination of the juror without objections of either party.
    When asked whether she had spoken to anyone about the case, the juror
    stated, “I don’t believe I did. I think I said I was a juror maybe, you know,
    or they knew I was a juror.” When asked whether she had expressed an
    8
    opinion about Christensen’s guilt, she said she did not because she did
    not know.    When pressed whether she made any statements about
    Christensen’s guilt, she stated, “I don’t believe I did. I don’t think I ever
    said anything about his guilt or innocence.”       When asked if she was
    certain, the juror responded, “I’m trying to think. I don’t remember making
    any statements about the guilt or innocence because I do not know.”
    Christensen moved to remove the juror.       The district court denied the
    motion.
    Christensen again raised the issue of juror disqualification in a
    motion for new trial. The district court denied the motion, declaring the
    ruling, among others, was “consistent with and supported by existing Iowa
    law, and, more importantly, neither prejudiced Christensen nor violated
    his rights to a fair trial and due process of law under the constitutions of
    the United States and the State of Iowa.”
    F. Overview of Alleged Prosecutorial Misconduct.
    1. Presumption of innocence/burden of proof. During the trial, the
    State called criminalist Tara Scott as a witness. During her examination,
    Scott testified that DNA from Bortvit was detected on the grip of the
    handgun asserted to be the weapon used to kill him. She also testified
    that the handgun was not screened for blood and that forensic testing was
    not conducted to determine if the source of the DNA was Bortvit’s skin or
    perspiration (which might suggest Bortvit at one point held the gun).
    Further, on cross-examination, Scott testified that scrapings found
    underneath Bortvit’s fingernails were not tested because Scott had been
    told that “no struggle was indicated.”
    On redirect, the prosecution asked Scott if the physical evidence was
    available for testing by others. Scott testified that it was. Christensen
    objected and asked to be heard outside the presence of the jury. Outside
    9
    the jury’s presence, Christensen objected to the question and answer
    which “inferred that the defendant has not taken steps to prove his own
    innocence.” Christensen argued the testimony violated the district court’s
    ruling in a motion in limine and constituted “a direct comment on the
    defendant’s presumption of innocence and the burden of proof in this
    case.” In light of the statement, Christensen said that the court could not
    “unring the bell.” He moved for a mistrial. The State responded that the
    questioning did not cross the line, that the answer was not clear, and in
    any event, that a curative instruction would be sufficient to cure any error.
    The district court concluded that the questioning did not violate the
    motion in limine but did have the implication that the defendant has an
    obligation to prove his innocence. This, the court said, was improper. The
    court determined that rather than grant a mistrial, it would provide the
    jury with a curative instruction.
    When the jury returned to the courtroom, the district court told the
    jury:
    There was . . . a question by [the prosecution] to the effect that
    [items of evidence] were available for someone else to test
    them; is that right? And the answer was yes. At that time
    there was the objection made. I will tell you now that line of
    questioning was improper because in my opinion that
    reversed the roles that have been clearly stated to you several
    times now by suggesting that the defendant somehow has an
    obligation to prove his innocence. We’ve told you many, many
    times, including in our preliminary instructions that that is
    not the case. So, at this point in time, I am directing you to
    disregard that line of questioning and disregard those answers
    because, again, those were improper.                Understood?
    Everybody please acknowledge. I’ll acknowledge that all
    members of the jury have confirmed their understanding.
    2. False testimony.    The State also called DCI investigator Peter
    Wagner as a witness. Wagner testified he used a metal detector to search
    for shell casings on the Christensen farm to determine where Bortvit’s fatal
    10
    injuries were inflicted. Wagner offered inconsistent testimony on cross-
    examination as to whether a metal detector had, in fact, been used.
    Wagner acknowledged that he stated in a pretrial deposition that he was
    unsure whether a metal detector was used. On redirect, however, Wagner
    claimed that he had spoken with another crime scene investigator, Keri
    Davis, during a lunch recess and that she told him a metal detector had,
    in fact, been used.
    After the redirect examination, Christensen’s counsel contacted
    Davis, who confirmed she had talked with Wagner but told him that a
    metal detector was not used at the scene because the middle rod of the
    detector was missing.        Christensen’s counsel moved for a mistrial,
    asserting the State had introduced false testimony.
    The district court had Davis testify by phone in chambers.       She
    confirmed what defense counsel had told the court, namely, that the metal
    detector was not used, that she had not told Wagner the metal detector
    was used, and that she had not told Wagner her deposition testimony to
    that effect was incorrect.
    The district court did not grant Christensen’s motion for mistrial.
    Yet, the district court was plainly concerned. In chambers outside the
    presence of the jury, the district court stated that it did not find Wagner
    “intentionally falsif[ied]” his testimony but that it “borders on reckless
    because it strictly was an opinion that he reached based on his discussions
    with [Davis].” The district court advised Wagner that “[he] came very close
    to having recklessly offered false testimony here” and that he should be
    “very careful” when he phrased his answers to questions.
    When the jury returned to the courtroom, the district court
    addressed the question of Wagner’s testimony. The district court noted
    that Wagner had provided testimony concerning statements attributed to
    11
    Keri Davis, a fellow investigator at the scene, which Wagner attributed to
    her from a conversation between the two of them made over the lunch
    recess. The district court then stated,
    As those statements currently are in the record, I believe they
    could easily be construed by you as somewhat misleading,
    and so at my request and at my direction, the state is going to
    recall Mr. Wagner to further clarify and explain that
    testimony.
    Pursuant to the court’s instructions, Wagner was recalled as a
    witness. Wagner testified that Davis had told him the metal detector was
    broken at the scene. Because the broken metal detector was at the scene,
    Wagner testified he assumed that Davis remembered him using it but she
    did not say that in the conversation. Yet, Wagner insisted that he, in fact,
    used the metal detector at the scene although its extension piece was
    missing.
    Christensen raised the question of prosecutorial misconduct in his
    motion for a new trial. The district court denied the motion.
    G. Jury    Questions     During      Deliberations.    After the jury
    commenced deliberations on June 30, the jury asked the district court for
    clarification of the court’s instructions. Specifically, the jury asked, “Could
    we have further instructions on malice aforethought?” The parties agreed
    the proper response to this question by the district court should simply be
    to instruct the jury to follow the instructions previously given.
    On July 1, the jury sent a second note stating, “We are stuck
    between two verdicts and need to know what our options are.” With the
    agreement of the parties, the district court responded they should
    continue to deliberate if they believed it would be productive in reaching a
    unanimous verdict.
    12
    H. Motion for a New Trial Based on Jury Misconduct and Bias.
    1. Introduction.   After the jury returned its verdict, Christensen
    learned about a Facebook post by “E’ville Amy” made public while the case
    was still before the jury. In order to understand the context, we reproduce
    the entirety of the Facebook post in the record:
    There is a lot of anger expressed on this page at the delay in
    verdict and the possible reasons for the delay. I was told a
    couple of times at downtown market tonight that there’s
    rumors of a possible riot if it’s not a verdict of guilty: first
    degree murder.
    I don’t know if the rumors have any substance but I want to
    use this platform you have grown around my reporting here
    to say: please. do. not. do. this. This community can not
    sustain a riot right now. (To be clear, there’s never a good
    time to riot. Peaceful demonstration against injustice ~ yes.
    That’s an inalienable right as an American. But how often
    have these things become anything but peaceful in our age?)
    It won’t return Thomas Bortvit to us. It won’t bring the clock
    back to June 5 before the chain of events that caused the
    shooting. It won’t change the fact that another son of our
    community will go away for a long time. You may in a certain
    scenario believe it’s not long enough, but who can take a
    stopwatch to the pain of loss–of a life and of what could have
    been.
    If you think some might consider rioting, use your influence
    to stop them.
    It won’t bring Thomas back. Alternatively, from what I’ve
    observed, being kind to one another will let a little sliver of his
    spirit shine through, if just for a moment.
    We have to live here as family and community for years to
    come. The only way I can see for the ripped apart places to be
    whole again is love, peace, compassion, kindness, and
    understanding.
    Christensen moved for a poll of the jury to determine whether the
    jury verdict might have been tainted by exposure to the Facebook posting
    or other outside influences. The district court granted the motion. The
    13
    district court held proceedings to poll the jury on October 18, 2018, more
    than three months after the jury rendered its verdict.
    2. Evidence adduced at jury poll. During the poll, each juror was
    asked whether they heard or saw any comments in the news media, from
    social media like Facebook, or from friends in the community that there
    might be some sort of riot or violence if Christensen was not found guilty
    of a certain offense.    They were also asked whether they heard any
    discussion by other jurors about a potential riot. Finally, if the answer
    was yes, the jurors were asked when they heard the discussion or
    commentary.
    The first juror polled, S.G., when asked whether she heard before
    the jury reached its verdict of a threat of some sort of riot or violence or
    some kind of public disturbance if Christensen was not found guilty of
    something, testified, “No, sir, I didn’t hear it before we reached our verdict,
    no.” When asked if other jurors made comments along those lines, S.G.
    stated, “Not that I can recall, no.” When pressed, S.G. again stated, “I
    don’t think that it was mentioned before we reached our verdict that I know
    of.” When asked if there was a possibility that such a statement was made
    by another juror before the verdict was rendered, S.G. testified, “I’m going
    to say no, there wasn’t any that I -- no, not even a possibility in my mind.”
    The second juror, B.W., testified that he personally did not see or
    hear anything related to violence outside the jury room but that “[he] did
    hear in the jury room that some people had seen it on Facebook.” When
    asked what specifically came up, B.W. stated, “[T]here were some threats
    against the jury depending on what -- whatever decision was made” and
    that jurors “just said that there are people threatening the jury.” B.W.
    stated the statements were made by two female jurors. When asked at
    what point in the proceedings the statements were made, B.W. responded,
    14
    I would say it wasn’t part of our proceedings at all, you know,
    as far as the decision we reached, but it was said after that
    basically hey, could we get somebody to walk us to our
    vehicles because some of the jurors were feeling like there
    was, you know, obviously tension in the courtroom, but also
    that they had seen some things on Facebook.
    Further, in response to a question about whether the threats concerned a
    particular verdict, B.W. replied,
    That’s a really good question. I don’t think it was dependent
    on what specific decision was made by the jury, just that there
    were people on both sides of the issue about whatever the
    decision would be made, and so that had an impact on, you
    know, the jury feeling safe.
    The third juror, M.S., testified to a lack of knowledge about any
    possible threat of violence “until after the decision was made.” According
    to M.S., she learned of the threat of violence as an explanation for why the
    jury was assisted out of the courthouse. M.S. recalled, however, that a
    comment in the jury room “had been mentioned a few days earlier.” M.S.
    recalled that “the person talked to the judge about it.” When the court
    advised M.S. that it did not remember such a conversation, the juror
    responded, “[M]aybe we just discussed that maybe we should.” M.S. did
    not remember who the juror was, but testified it was a female juror who
    “had been told that it was all over Facebook” and who said “[s]omething to
    the effect that her granddaughter had read it on Facebook.” When asked
    if the comment was made at the conclusion of the evidence, while the jury
    was deliberating, or before that time, the juror responded, “before that
    time” and during the course of the trial.
    The fourth juror, K.K., testified that she had heard “there had been
    talk about a riot if [Christensen] wasn’t found guilty.” When asked where
    she heard that, she stated, “I just heard it somewhere.       I don’t know
    where.”   She also stated that at the time, she thought it “sounded
    ridiculous and that was it.”        She indicated she heard the comment
    15
    sometime during the trial. She testified that she heard it out in the public
    somewhere, that the comment was not directed at her, and that she did
    not share what she heard with the jury. When asked if she heard other
    members of the jury talking about something similar, she responded, “Not
    that I recall.”
    The fifth juror, T.L., testified that she did not hear of a threat of
    violence outside the jury room but that one of the other jurors made a
    comment that “they heard that if [the jury] didn’t vote for first degree
    murder that there was going to be -- people were going to be mad or be
    outside the courthouse, something to that effect.” She did not remember
    when the comment was made or how many persons heard the comment.
    She said it was “fairly dismissed.”
    The sixth juror, J.A., testified that she had not heard of the threat
    of violence outside the jury room but that it was brought up by a jury
    member. According to J.A., a juror stated that “someone had told them
    that if it wasn’t first degree that there would be a riot.” J.A. recalled the
    comment was made “after we had made our verdict” but before the verdict
    was announced in the courtroom.
    The seventh juror, K.B., testified that she had not heard of a threat
    of violence and that she did not remember any such discussion by the
    jury.
    The eighth juror, A.F., testified that she had not heard of the threat
    of violence outside the jury room but recalled some discussion after the
    decision had been made and announced in the courtroom. She recalled,
    “I think somebody said something about a post on Facebook.” The juror
    recalled that the commenting juror received the information about
    Facebook from someone else.           She believed that the sheriff’s office
    16
    personnel escorted the jurors to their cars because of what the juror had
    said or heard.
    The ninth juror and jury foreperson, G.S., did not hear of any threat
    of violence outside the jury room. He did recall other jurors stating that
    they had heard something of that nature. He did not remember if the
    concern over safety occurred before the verdict or after the verdict, “but
    the concern was the safety of the jurors after the trial was over.” G.S.
    testified, “I took a survey or a vote to see who was worried about their
    safety, and most people raised their hands.” When asked whether the
    source of the concern was due to a threat or something else coming from
    outside the courtroom, or instead was based on the emotional nature of
    the proceeding, G.S. stated, “I would say the emotional, yeah. It was highly
    charged. There was a lot of emotional pressure in the jury room, as one
    might expect, and that was bothersome.”
    The tenth juror, R.D., testified that she did not hear of a threat of
    violence outside the jury room. She also did not remember any discussion
    of a threat of violence inside the jury room.
    The eleventh juror, M.H., testified that she did not hear of any threat
    of violence outside the jury room, but remembers a comment in the jury
    room that “there might be, like, a possible riot at the courthouse.” She
    testified that the comment was made on Friday prior to the jury resuming
    deliberations. M.H. recalled that the juror heard about the threat in a
    telephone conversation, that the source of the information was a family
    member, and that the juror’s comment about a possible riot occurred on
    a day before the jury returned to the courthouse to deliberate.
    The twelfth juror, T.J., testified she did not hear outside the jury
    room about a riot or some sort of public disturbance if Christensen was
    not found guilty of something.      She did recall such a comment and
    17
    discussion by the jury but only after the verdict was announced. She
    testified that juror A.F. was very emotional, was crying quite a bit, and
    stated that “she had heard that somebody -- that there was a possible --
    going to be a riot.” T.J. stated, “[T]hat’s all that was said.” As a result,
    T.J. testified the jury asked to have deputies walk them out of the
    courthouse.
    At the close of the polling of the jurors, the district court made a
    statement on the record. The district court said statements were made to
    the court after trial that the
    jurors, based on their belief that this obviously was an
    emotionally charged case from what they had seen in the
    courtroom, their concerns over all of the family members and
    the public that had been here during the course of the trial,
    [and] that they could be confronted by those individuals upon
    leaving the courthouse, . . . requested safety escorts.
    There was absolutely no statement made to [the court]
    about anybody seeing anything on Facebook, social media, or
    having heard anything out in the community that would have
    led to them having those safety concerns.
    3. District court ruling on motion for a new trial. In his motion for a
    new trial, Christensen argued that the record established juror
    misconduct and jury bias. The district court denied relief.
    In its posttrial ruling, the district court summarized the testimony
    of the jurors. The district court considered whether the jurors saw or
    heard about the E’ville Amy Facebook post outside the courthouse. The
    district court noted that none of the jurors testified they saw or read the
    Facebook posting by E’ville Amy.
    The district court considered the question of when the jury heard
    about the possibility of public violence. The district court noted that five
    jurors acknowledged they heard about the possibility of a riot or public
    violence from another juror if a certain verdict was not reached.       But,
    18
    according to the district court, only one juror could recall which juror
    made the statement. The district court also observed that one juror heard
    about a possible riot in the community but called it “ridiculous.”
    Further, the district court stated three jurors testified they did not
    recall any discussion of public violence and two other jurors believed the
    jurors’ safety concerns were due, at least in part, to the tension in the
    courtroom between friends and family members of the Christensen and
    Bortvit families. The district court noted the jury foreperson, G.S., took a
    survey of the jurors to see if they felt unsafe after their verdict had been
    read, and when a majority of jurors raised their hands, the court was
    notified of the concern. When the court was informed of the jury’s concern
    after the verdict was rendered, the court stated that no mention was made
    about comments on Facebook or about someone having heard something
    that led the jurors to perceive a threat to their safety.
    The district court further observed three jurors testified that the
    possibility of a public disturbance or public violence had been brought up
    by another juror during the course of the trial and before the jury reached
    its verdict. These three jurors, however, could not recall who brought up
    the issue. Two of the three jurors, the court noted, could not recall when
    the juror commented on the possibility of violence.
    After summarizing the jurors’ testimony, the district court applied a
    multifactor test set forth in State v. Cullen, 
    357 N.W.2d 24
    , 27 (Iowa 1984),
    abrogated on other grounds by Ryan v. Arneson, 
    422 N.W.2d 491
    , 495
    (Iowa 1988), to determine whether to grant Christensen a new trial based
    on juror misconduct. Based on its review of the record, the district court
    concluded Christensen failed to meet the Cullen test.
    To determine whether to grant Christensen a new trial based on
    juror bias, the district court considered State v. Webster, 
    865 N.W.2d 223
    ,
    19
    236–39 (Iowa 2015). The court held Christensen did not meet his burden
    of showing juror bias.
    II. Discussion of Juror Disqualification.
    A. Introduction.      Christensen seeks a new trial because of the
    alleged bias of juror K.B. Iowa Rule of Criminal Procedure 2.24(2)(b)(9)
    provides that a court may grant a new trial when “the defendant has not
    received a fair and impartial trial.”     As we noted in Webster, “a jury
    consisting of eleven impartial jurors and one actually biased juror is
    constitutionally infirm without any showing that there was juror
    
    misconduct.” 865 N.W.2d at 237
    n.7.
    B. Positions of the Parties.
    1. Christensen’s position.    Christensen claims the district court
    committed reversible error when it refused to disqualify juror K.B. for
    potential bias. He contends that while a district court decision denying a
    motion for new trial is ordinarily reviewed for an abuse of discretion, we
    review fact-finding de novo when constitutional issues are involved.
    Christensen emphasizes the language used by K.B. when pressed
    about whether she had made any out-of-court statement declaring
    Christensen guilty.      Christensen points out that K.B.’s answers when
    asked about making statements about Christensen’s guilt or innocence
    were guarded and circumspect: “I don’t believe I did” and “I don’t think I
    ever said anything about his guilt or innocence.” (Emphasis added.)
    In support of his argument, Christensen cites State v. Beckwith, 
    242 Iowa 228
    , 238–39, 
    46 N.W.2d 20
    , 26 (1951), abrogated on other grounds
    by State v. Neuendorf, 
    509 N.W.2d 743
    , 746 (Iowa 1993). In Beckwith, this
    court cautioned that “trial courts should use the utmost caution in
    overruling challenges for cause in criminal cases when there appears to be
    a fair question as to their soundness.” 
    Id. at 238,
    46 N.W.2d at 26. The
    20
    Beckwith court noted that while a ruling might be technically sound, “it is
    far better to give the accused the benefit of the doubt.” 
    Id. at 239,
    46
    N.W.2d at 26.
    2. The State’s position. The State counters that the standard to be
    applied to a question of juror disqualification is abuse of discretion.
    
    Webster, 865 N.W.2d at 231
    . The State recognizes an abuse of discretion
    occurs when a district court order is based on an erroneous application of
    law. See State v. Rodriquez, 
    636 N.W.2d 234
    , 239 (Iowa 2001). And, even
    if the case involves a constitutional question subject to de novo review, the
    State emphasizes that the reviewing court gives some deference to
    credibility determinations made by the district court. See State v. Carter,
    
    696 N.W.2d 31
    , 36 (Iowa 2005).
    The State urges us to examine the record made regarding the motion
    to disqualify K.B. The State notes that K.B. repeatedly stated she had not
    come to a decision regarding the guilt or innocence of the accused.
    Further, the State notes there was no factual showing the juror actually
    stated at a family event that she believed the defendant was guilty.
    C. Discussion. On the issue of juror disqualification, we do not
    decide whether the standard of review is de novo or abuse of discretion.
    As in Webster, we generally agree with the fact-finding of the district 
    court. 865 N.W.2d at 231
    n.4.
    Christensen’s cited case of Beckwith provides sound advice to the
    district court, namely, that it makes practical sense to error on the side of
    caution on a question of jury disqualification. In this case, there were two
    alternate jurors available to take the place of a dismissed juror.
    Yet, the Beckwith advice to judges to be cautious when there is a
    close question of disqualification for cause does not alter the requirement
    that the defendant establish a sufficient basis to support disqualification
    21
    of a juror. Here, there was no direct evidence the juror actually made the
    alleged statements about Christensen’s guilt. Rather, there was only an
    anonymous note summarizing a coffee shop discussion. No one testified
    that juror K.B. actually made the statements attributed to her in the
    anonymous coffee shop note. The qualified language used by the juror
    when she was questioned about the alleged statement, of course, is a
    factor, and in some cases might be an important factor, 1 but here, the
    evidence that she actually made the potentially disqualifying statements
    attributed to her is hearsay upon hearsay and generally denied by the
    juror. Had credible testimony been offered showing that K.B. did, in fact,
    1Social science research suggest that the language actually used by a witness
    provides a much better barometer of credibility than witness demeanor, which is often
    misleading. In two pioneering articles, legal academics reviewing the social science
    literature explain that visual cues are significantly worse than language content in
    assessing credibility. Jeremy A. Blumenthal, A Wipe of the Hands, a Lick of the Lips: The
    Validity of Demeanor Evidence in Assessing Witness Credibility, 
    72 Neb. L
    . Rev. 1157,
    1203 (1993) (“[R]esearch has shown that observers exposed to a witness’ voice are able
    to judge deceit best, and those exposed to merely a transcript and no ‘demeanor cues’ do
    almost as well, up to twice as well as those who are exposed to visual cues. Thus, there
    is support for the claim that findings of credibility could be reviewed de novo by appellate
    courts.” (Footnote omitted.)); Olin Guy Welborn III, Demeanor, 76 Cornell L. Rev. 1075,
    1075, 1104–05 (1991) (“According to the empirical evidence, ordinary people cannot make
    effective use of demeanor in deciding whether to believe a witness. On the contrary, there
    is some evidence that the observation of demeanor diminishes rather than enhances the
    accuracy of credibility judgments. . . . To the extent that people can detect lying or
    erroneous beliefs in another, they do so primarily by paying close attention to the content
    of what the other says, not by observing facial expression, posture, tone of voice, or other
    nonverbal behavior.”). Later research has confirmed the accuracy of those two articles
    and further explains how juror biases and information asymmetry can affect lie detection.
    Max Minzner, Detecting Lies Using Demeanor, Bias, and Context, 29 Cardozo L. Rev. 2557,
    2558, 2578 (2008). Relying on the social science research, courts have expressed unease
    with dependence on demeanor evidence to assess credibility because of its tendency to
    mislead. See, e.g., United States v. Pickering, 
    794 F.3d 802
    , 805 (7th Cir. 2015)
    (“[D]emeanor evidence, such as tone of voice, or gestures or posture, can be an unreliable
    clue to truthfulness or untruthfulness, and thus distract a trier of fact from the cognitive
    content of a witness’s testimony.”); United States v. Shonubi, 
    895 F. Supp. 460
    , 481
    (E.D.N.Y. 1995) (“Gauging credibility is the best known application of demeanor.
    Ironically, this may be one of its least effective uses.”), vacated on other grounds, 
    103 F.3d 1085
    (2d Cir. 1997); State v. Rogerson, 
    855 N.W.2d 495
    , 509–10 (Iowa 2014) (Hecht, J.,
    concurring specially) (explaining that “intuitive assumptions” that physical distance and
    vision-blocking screens between a witness and defendant “bear[] on the assessment of
    reliability may be true, but maybe not”).
    22
    make the statements attributed to her, we would have a different scenario.
    In light of the record developed in this case, however, we decline to disturb
    the ruling of the district court.
    III. Discussion of Prosecutorial Misconduct.
    A. Positions of the Parties.
    1. Christensen’s position.    Christensen asserts the district court
    erred in failing to grant him a new trial based upon prosecutorial
    misconduct. See State v. Graves, 
    668 N.W.2d 860
    , 867 (Iowa 2003); State
    v. Piper, 
    663 N.W.2d 894
    , 913 (Iowa 2003), overruled on other grounds by
    State v. Hanes, 
    790 N.W.2d 545
    , 551 (Iowa 2010). Christensen argues
    prosecutorial misconduct occurred when the State elicited testimony from
    Tara Scott that the physical evidence was available for testing by others.
    In support of that claim he cites 
    Hanes, 790 N.W.2d at 556
    . In Hanes, we
    held that the state bears the burden of proof in a criminal prosecution and
    that it was improper for the state to attempt to shift the burden to the
    defense by suggesting that the defense could have called additional
    witnesses. 
    Id. Christensen recognizes
    the district court sustained his objection to
    the Scott testimony and instructed the jury to disregard the question and
    the answer. According to Christensen, however, this was a case in which
    the proverbial bell, when once rung, cannot be unrung.         See State v.
    Jackson, 
    587 N.W.2d 764
    , 766 (Iowa 1998) (“[A] reversal may only be
    predicated on the proposition that the matter forbidden by the ruling was
    so prejudicial that its effect upon the jury could not be erased by the trial
    court’s admonition.”); State v. Williamson, 
    570 N.W.2d 770
    , 771 (Iowa
    1997) (same).
    Christensen also cites the testimony of Peter Wagner as establishing
    prosecutorial misconduct. According to Christensen, Wagner’s testimony
    23
    that a metal detector was used by investigators at the Christensen farm
    was false and misleading. According to Christensen, a prosecutor’s use of
    false testimony violates due process. See DeVoss v. State, 
    648 N.W.2d 56
    ,
    64 (Iowa 2002).     Christensen notes the district court observed that
    Wagner’s testimony “bordered on the reckless.”            Yet Christensen
    recognizes the court admonished the jury that Wagner’s testimony was
    misleading and provided Wagner with an opportunity to “clarify” his
    testimony.
    2. The State’s position.      The State counters there was no
    prosecutorial misconduct and, to the extent any may have occurred, it was
    cured by the actions taken by the district court.      On the question of
    whether it was improper for Scott to testify that evidence was available for
    testing by others, the State does not discuss Hanes but instead relies on
    the earlier case of State v. Craig, 
    490 N.W.2d 795
    , 797 (Iowa 1992). In
    Craig, we stated that “a prosecutor may properly comment upon the
    defendant’s failure to present exculpatory evidence, so long as it is not
    phrased to call attention to the defendant’s own failure to testify.” 
    Id. (emphasis omitted)
    (quoting State v. Bishop, 
    387 N.W.2d 554
    , 563 (Iowa
    1986)).
    With respect to the Wagner testimony, the State maintains
    Christensen failed to show the testimony about the telephone conversation
    with Davis was false, as neither Wagner nor Davis remembered what was
    specifically said. Further, the State suggests the prosecution had another
    witness who testified that Wagner used a metal detector.
    In any event, in order for prosecutorial misconduct to be present,
    the State argues, Christensen must show that the State knew the
    testimony was false and that the false testimony was material to the case.
    See Hamann v. State, 
    324 N.W.2d 906
    , 909 (Iowa 1982). The State asserts
    24
    that Christensen failed to show that the State knew the testimony was
    false and that the dust-up over whether a metal detector was used to locate
    metal objects at the Christensen farm is not the kind of question that
    would influence the verdict in this case.
    B. Discussion.    We conclude the State has the better argument
    with respect to the prosecutorial misconduct claim arising out of the Scott
    testimony. Her testimony crossed the line established in Hanes, a case
    which the State declined to address. Yet, upon objection, the district court
    excluded the evidence and directed the jury to disregard it.
    We do not think the error was so serious to require a mistrial. We
    have said that a prosecutor’s misconduct will not warrant a new trial
    unless the conduct was so prejudicial as to deprive the defendant of a fair
    trial. State v. Pace, 
    602 N.W.2d 764
    , 774 (Iowa 1999). We have noted that
    “[p]rejudice can, but usually does not, result from isolated prosecutorial
    misconduct.” State v. Anderson, 
    448 N.W.2d 32
    , 34 (Iowa 1989). Here,
    the prosecutorial misconduct was an isolated event and was not as
    prejudicial as, say, a comment on the defendant’s failure to testify in his
    or her own defense.
    Further, as both parties recognize, we have stated curative
    instructions are generally sufficient to cure most trial errors. See State v.
    Plaster, 
    424 N.W.2d 226
    , 232 (Iowa 1997). Here, the improper question,
    the answer, the motion to strike, and the curative instruction happened in
    rapid succession.     The testimony stricken was not of a startling or
    flamboyant nature that was likely to make an indelible impression on the
    jury. We think the district court’s response to the timely objection at trial
    provided an adequate remedy to Scott’s inappropriate testimony.
    We also reject Christensen’s assertion that he is entitled to a new
    trial based upon Wagner’s alleged misconduct. The district court found
    25
    Wagner’s testimony regarding his conversation with Davis troubling, and
    so do we. But the record does not support a conclusion the State was
    aware, or should have been aware, of a plan by Wagner to present false
    testimony. See 
    Hamann, 324 N.W.2d at 909
    . Further, Wagner returned
    to the stand to clarify his prior misleading testimony about his
    conversation with Davis. Ultimately, the jury was not materially misled,
    and Wagner’s credibility was clearly damaged by his misstep.                 This
    singular event on a collateral issue does not provide the basis for a new
    trial.
    IV. Discussion of Jury Misconduct and Bias.
    A. Introduction. The Sixth and Fourteenth Amendments to the
    United States Constitution and article I, sections 9 and 10 of the Iowa
    Constitution guarantee a criminal defendant the right to a fair trial before
    an impartial jury. U.S. Const. amends. VI, XIV; Iowa Const. art. I, §§ 9,
    10; Irvin v. Dowd, 
    366 U.S. 717
    , 722, 
    81 S. Ct. 1639
    , 1642 (1961). The
    jury is constitutionally required to base its verdict on the evidence
    developed at trial. 
    Irvin, 366 U.S. at 722
    , 81 S. Ct. at 1642. The partiality
    of one juror due to extraneous influence is sufficient to deny the defendant
    the constitutional guarantee of an impartial trial. Parker v. Gladden, 
    385 U.S. 363
    , 366, 
    87 S. Ct. 468
    , 471 (1966) (“[P]etitioner was entitled to be
    tried by 12, not 9 or even 10, impartial and unprejudiced jurors.”);
    
    Webster, 865 N.W.2d at 237
    n.7 (“[A] jury consisting of eleven impartial
    jurors and one actually biased juror is constitutionally infirm . . . .”).
    The constitutional right to an impartial jury may be impaired by jury
    misconduct and jury bias. The concepts of juror misconduct and juror
    bias are often related but are somewhat different in nature. 
    Webster, 865 N.W.2d at 232
    . Juror misconduct often involves communication by a juror
    with others about the case outside the jury room, independently
    26
    investigating the crime, or engaging in independent research on questions
    of law or fact. 
    Id. Juror bias,
    on the other hand, does not necessarily
    involve juror misconduct, but arises when a juror is unable to fairly engage
    in a determination of guilt or innocence based on the evidence at trial and
    the court’s instructions. 
    Id. Under our
    rules of criminal procedure, a defendant may be entitled
    to a new trial when the jury “have been guilty of any misconduct tending
    to prevent a fair and just consideration of the case.” Iowa R. Crim. P.
    2.24(2)(b)(3). Our rules also provide for a new trial if “the jury has received
    any evidence . . . not authorized by the court.” 
    Id. r. 2.24(2)(b)(2).
    Finally,
    our rules provide that a new trial may be granted when “the defendant has
    not received a fair and impartial trial.” 
    Id. r. 2.24(2)(b)(9).
    Also relevant is Iowa Rule of Evidence 5.606(b). Under this rule, a
    juror is generally prohibited from testifying about jury deliberations except
    a juror may testify about whether any extraneous information was
    improperly brought to the attention of the jury. 
    Id. B. Positions
    of the Parties.
    1. Christensen’s position. Christensen argues that he is entitled to
    a new trial based on jury misconduct and jury bias. He cites the authority
    to grant a new trial in Iowa Rules of Criminal Procedure 2.24(2)(b)(2),
    (2)(b)(3), and (2)(b)(9).   Christensen argues that although a denial of a
    motion for new trial based upon juror misconduct or juror bias is reviewed
    for an abuse of discretion, we review fact-finding de novo when
    constitutional issues are involved.
    The thrust of his claim is that a juror or jurors learned from sources
    outside the jury there might be a riot at the courthouse in the event the
    jury did not return a certain verdict. The juror or jurors then told other
    27
    jurors of the possibility of a riot.       Christensen claims these events
    prevented him from getting a fair trial.
    In pressing his claim, Christensen urges us to apply a test presented
    in Remmer v. United States, 
    347 U.S. 227
    , 229, 
    74 S. Ct. 450
    , 451 (1954).
    In Remmer, the Supreme Court stated that “[i]n a criminal case, any
    private communication, contact, or tampering directly or indirectly, with a
    juror during a trial about the matter pending before the jury is, for obvious
    reasons, deemed presumptively prejudicial.” 
    Id. The Remmer
    Court noted
    that “[t]he presumption is not conclusive, but the burden rests heavily
    upon the Government to establish, after notice to and hearing of the
    defendant, that such contact with the juror was harmless to the
    defendant.”   
    Id. The case
    was remanded to allow the government to
    attempt to meet its burden. 
    Id. at 230,
    74 S. Ct. at 451–52.
    Christensen cites a number of federal circuit court cases in support
    of a relatively stringent test. For instance, Christensen cites United States
    v. Dutkel, 
    192 F.3d 893
    , 897–98 (9th Cir. 1999), abrogated on other
    grounds by Godoy v. Spearman, 
    861 F.3d 956
    , 968 n.6 (9th Cir. 2017) (en
    banc). In Dutkel, the United States Court of Appeals for the Ninth Circuit
    held that a prima facie showing of jury tampering triggered a presumption
    of prejudice and that the court should inquire whether “the intervention
    interfered with the jury’s deliberations by distracting one or more of the
    jurors, or by introducing some other extraneous factor into the deliberative
    process.” 
    Id. at 897.
    Christensen cites several additional cases for the
    proposition that the court should engage in stringent review when there
    are claims of external influence on a jury. See United States v. Rutherford,
    
    371 F.3d 634
    , 644 (9th Cir. 2004) (“The appropriate inquiry is whether the
    unauthorized conduct ‘raises a risk of influencing the verdict,’ or ‘had an
    adverse effect on the deliberations.’ ” (first quoting Caliendo v. Warden of
    28
    Cal. Men’s Colony, 
    365 F.3d 691
    , 697 (9th Cir. 2004); and then quoting
    United States v. Henley, 
    238 F.3d 1111
    , 1117 (9th Cir. 2001)); United
    States v. Tucker, 
    137 F.3d 1016
    , 1031 (8th Cir. 1998) (“The question of
    prejudice depends on whether ‘there is any reasonable chance that the
    jury would have been deadlocked or would have reached a different verdict
    but for the fact that even one reasonable juror was exposed to prejudicial
    extraneous matter.’ ” (emphasis omitted) (quoting United States v. Hall,
    
    116 F.3d 1253
    , 1255 (8th Cir. 1997)); United States v. Cheek, 
    94 F.3d 136
    ,
    144 (4th Cir. 1996) (granting relief where one juror, exposed to bribery
    attempt, was “devastated and fearful”).
    Christensen also urges us to apply a “heightened scrutiny” test
    adopted in State v. Carey, 
    165 N.W.2d 27
    , 30 (Iowa 1969). In Carey, we
    considered, among other issues, the impact of a sign in the jury room
    indicating that the coffee was being jointly provided by the county clerk
    and the county attorney.      
    Id. at 28.
      We emphasized, “Our anxiety to
    protect the jury from any conduct which would lessen public confidence
    in our judicial system should be even greater in a criminal trial.” 
    Id. at 30.
    Citing the coffee sign and other errors, we reversed the conviction. 
    Id. Christensen argues
    that the heightened scrutiny afforded by Carey in
    criminal cases was recognized in 
    Cullen, 357 N.W.2d at 27
    .
    Applying heightened scrutiny under Remmer or Carey, Christensen
    argues, he is entitled to a new trial because of juror misconduct.
    Christensen asserts that the misconduct arose when jurors received
    external information about the possibility of a riot if a certain verdict was
    not returned and when this information was communicated to the jury
    during their deliberations.
    Christensen canvasses the record developed in the jury poll to
    support his mistrial motion. Christensen notes that one juror testified
    29
    that two jurors had seen a Facebook post indicating that people were
    threatening violence depending on what decision the jury made.           He
    emphasizes testimony that those two jurors saw postings about violence
    against the jury. Viewing Facebook postings about the trial, according to
    Christensen, would violate the instructions of the court to avoid contact
    with social media. Christensen notes that one juror testified that another
    juror told the jury that she had overheard talk in the community about a
    riot if the defendant was found not guilty.
    The misconduct continued, Christensen asserts, when the jurors
    shared the extraneous information with other members of the jury.
    Christensen observes the jury poll demonstrated that nine of the twelve
    jurors were aware of the potential threat. He further notes that one juror
    testified that comments were made about the threat a few days before the
    verdict was rendered and before the conclusion of evidence. In addition,
    he points out, two jurors recalled that another juror had spoken by
    telephone with a family member about the riot threat before the jury
    returned to continue its deliberations on Friday.
    Christensen argues the threat had an impact on the jurors’ concern
    for their own safety. Christensen cites the testimony of the jury foreperson
    who stated that after the verdict was rendered, he took a poll of jurors and
    a majority raised their hands when asked whether they were concerned
    about their personal safety. Christensen points out juror testimony that
    the perceived threat played a role in the jury’s request for a police escort
    when jurors walked to their cars after rendering their verdict. Another
    juror, he notes, recalled being told the threat was “all over Facebook” and
    that this threat was the reason the jury was led out of the courthouse.
    Christensen also directs our attention to a third juror’s testimony
    concerning a juror who heard of the threat and was very emotional and
    30
    upset. He further points out that one juror was sufficiently alarmed about
    her safety to ask the sheriff to patrol her home after the conclusion of the
    trial.
    Christensen cites two cases from other jurisdictions in which threats
    of public violence gave rise to a change in venue. In Lozano v. State, 
    584 So. 2d 19
    , 22 (Fla. Dist. Ct. App. 1991) (per curiam), the Florida appellate
    court held that the district court erred in failing to grant a change of venue
    in a police shooting case that had attracted media attention and caused a
    Miami neighborhood to erupt into civil disturbance. The Lozano court
    noted that several jurors were affected by the fear of violence and that
    several had heard from friends or relatives that there might be a
    disturbance if the defendant was found guilty. 
    Id. at 22
    n.5. The Florida
    court stated,
    Surely, the fear that one’s own county would respond to a not
    guilty verdict by erupting into violence is as highly
    “impermissible [a] factor” as can be contemplated. Surely too,
    there was an overwhelmingly “unacceptable risk” of its having
    adversely affected Lozano’s—and every citizen’s—most basic
    right under our system: the one to a fair determination of his
    guilt or innocence based on the evidence alone.
    
    Id. at 22
    –23 (quoting Estelle v. Williams, 
    425 U.S. 501
    , 505, 
    96 S. Ct. 1691
    ,
    1693 (1976)).
    Christensen also cites Powell v. Superior Court, 
    283 Cal. Rptr. 777
    ,
    787 (Ct. App. 1991). In this case, the California appellate court confronted
    a situation in which white police officers were charged with assaulting
    Rodney King, an African-American man. 
    Id. at 778–80.
    In granting a
    change of venue, the Powell court noted that “[it] must draw the inevitable
    inference about the possibility of threats which would surface during the
    trial itself.” 
    Id. at 787.
    The Powell court found the possibility of threats of
    violence would “add another impermissible factor into the boiling cauldron
    31
    surrounding this case, making it imperative to take every step possible to
    ensure that an impartial unbiased jury be seated.” 
    Id. Under the
    circumstances here, Christensen contends there is no
    doubt that one or more jurors were exposed to the Facebook posting about
    a potential riot and that some of the jurors were exposed to this
    information as early as days before deliberation and certainly before the
    verdict was rendered. The jury poll, he notes, revealed that nine of the
    jurors were aware of discussion of a possible riot in the community if a
    certain verdict was not rendered, that one of them was emotionally upset
    about it, that the jury poll taken immediately after the verdict was
    rendered revealed sufficient concern that law enforcement escorted the
    jury from the courtroom, and that one of the jurors asked to have her home
    patrolled after the verdict was rendered.
    Christensen presses that the extraneous information about a
    potential riot was calculated to, and with reasonable probability did,
    influence the verdict.   While Christensen recognizes the district court
    noted that two jurors commented that they considered the threats
    “ridiculous” or “fairly dismissed,” such consideration was impermissible
    under Iowa Rule of Evidence 5.606(b). Christensen urges us to instead
    consider objectively the potential impact on the jury verdict. See State v.
    Henning, 
    545 N.W.2d 322
    , 325 (Iowa 1996). Noting twenty-four of sixty
    prospective jurors were disqualified for cause, Christensen argues that the
    case involved a star athlete killing a popular college student that generated
    community sentiment. If even one juror was not impartial as a result of
    the possibility of a riot, Christensen argues he is entitled to a new trial.
    See 
    Parker, 385 U.S. at 365
    –66, 87 S. Ct. at 471; 
    Webster, 865 N.W.2d at 237
    n.7.
    32
    2. The State’s position. The State suggests the proper standard of
    review for juror misconduct is abuse of discretion, citing 
    Webster, 865 N.W.2d at 231
    . The State again recognizes, however, that an erroneous
    application of law is an abuse of discretion. 
    Rodriquez, 636 N.W.2d at 239
    .
    The State also cites 
    Carter, 696 N.W.2d at 36
    , a case involving de novo
    review of constitutional issues, for the proposition that even when
    constitutional issues are involved, the court on appeal gives deference to
    findings of fact because of the district court’s ability to assess the
    credibility of witnesses.
    The State asserts that in seeking a new trial based on juror
    misconduct, a defendant must satisfy the multipronged approach outlined
    in 
    Cullen, 357 N.W.2d at 27
    , and utilized in 
    Webster, 865 N.W.2d at 235
    –
    36. First, the evidence bearing on misconduct must be based only on
    objective facts as to what occurred. 
    Webster, 865 N.W.2d at 234
    . Second,
    “the acts or statements complained of must exceed tolerable bounds of
    jury deliberation.” Id. (quoting 
    Cullen, 357 N.W.2d at 27
    ). Third, “it must
    appear the misconduct was calculated to, and with reasonable probability
    did, influence the verdict.” Id. (quoting 
    Cullen, 357 N.W.2d at 27
    ).
    In canvassing the jury poll record, the State argues there was no
    juror misconduct. The State asserts the evidence revealed that one juror
    apparently spoke to her granddaughter and the granddaughter—not the
    juror—saw the threat on Facebook. Another juror, according to the State,
    simply heard a community member comment about a threat to the jury’s
    safety. The State notes there was no evidence that a juror saw the threat
    by violating the court’s instruction against viewing material on social
    media. The State discounts the testimony of the juror who stated that two
    jurors had directly seen the threat on Facebook.
    33
    The State further recognizes that in State v. Johnson, 
    445 N.W.2d 337
    , 342 (Iowa 1989), overruled on other grounds by State v. Hill, 
    878 N.W.2d 269
    , 274–75 (Iowa 2016), we held that outside information relayed
    to the jury before or during jury deliberations exceeds the permissible
    bounds of jury deliberation. In Johnson, a juror told other jurors that one
    of the defendant’s victims “broke down” and cried in front of a teacher at
    school. 
    Id. at 339.
    The juror also told other jurors that he had heard
    rumors the defendant hit the victims. 
    Id. The State,
    however maintains
    that Johnson does not apply here because the district court concluded
    from its credibility findings that no juror discussed the threat during jury
    deliberations.
    Further, the State argues there was no reasonable probability the
    threat to the jurors’ safety affected the verdict.    The State relies on
    statements from some jurors that the threat was “ridiculous” and “fairly
    dismissed.”      While one juror was described as being upset, the State
    argues she did not hear of the threat until after the verdict. Finally, the
    State claims the jurors’ request for a police escort upon leaving the
    courthouse was attributed to all the family members and public attending
    the trial and a desire to avoid confrontation when leaving the courthouse.
    Finally, the State argues there was no reasonable probability that
    the jury’s verdict was impacted because the State’s evidence was so strong.
    The State notes the defendant admitted at trial, and to both his parents
    prior to trial, that he shot the victim.   The State further notes other
    evidence, such as the gun retrieved from the defendant’s home and his
    bloodstained pants and boots, supports the second-degree murder verdict.
    Finally, the State contends the evidence at trial established the defendant
    was upset with his ex-girlfriend.
    34
    C. Proper Framework for Evaluating Juror Misconduct.
    1. Introduction. The first issue we must resolve is the proper legal
    framework for determining whether a reversible case of jury misconduct is
    present. A district court that misapplies the legal test commits reversible
    error. 
    Rodriquez, 636 N.W.2d at 239
    . If the district court applied the
    correct test, the second issue that arises is the proper standard of review
    on appeal. Once we have determined the proper legal standard and the
    standard of review to be applied on appeal, we can then apply the law to
    the facts of this case.
    In considering these questions, we recognize there are two
    competing interests in considering how to handle juror misconduct. On
    the one hand, a core tenet of our system of government, enshrined in the
    right to counsel and due process provisions of the Iowa and United States
    Constitutions, is the notion that criminal convictions are imposed only by
    a fair and impartial jury based solely on the evidence.     See James W.
    Diehm, Impeachment of Jury Verdicts: Tanner v. United States and
    Beyond, 65 St. John’s L. Rev. 389, 393 (1991) [hereinafter Diehm].
    On the other hand, intrusive inquiries into jury deliberations could
    undermine right-to-counsel and due process goals.        See 
    id. If jurors
    understand the public will have access to deliberations, they may be more
    controlled by perceptions of public opinion than the evidence at hand. See
    
    id. at 438;
    Note, Public Disclosures of Jury Deliberations, 96 Harv. L. Rev.
    886, 894 (1983). As a result, jury privacy is essential to public confidence
    in the verdict. Tanner v. United States, 
    483 U.S. 107
    , 120–21, 
    107 S. Ct. 2739
    , 2748 (1987). Further, there is an interest in finality. 
    Id. at 120,
    107 S. Ct. at 2747. Attacking verdicts, sometimes years later, may put the
    prosecution at a disadvantage as memories fade, witnesses become
    unavailable, and evidence is lost. Diehm, 65 St. John’s L. Rev. at 402.
    35
    Yet, few would argue that finality considerations trump the need to avoid
    miscarriages of justice that may occur if a defendant is tried by a partial
    jury.
    The task is complicated by our evolving rules of evidence. Under
    Federal Rule of Evidence 606(b) and its Iowa counterpart, Iowa Rule of
    Evidence 5.606(b), a court is generally prohibited from inquiring into jury
    deliberations.      Although   inquiry     into   precisely   what   extraneous
    information was presented to a juror or jurors is permissible, exploration
    of the actual impact on jurors by asking them how the extraneous
    information impacted the deliberations and verdict is off limits. See United
    States v. Williams-Davis, 
    90 F.3d 490
    , 496 (D.C. Cir. 1996); State v. Wilson,
    
    878 N.W.2d 203
    , 210 (Iowa 2016). Further, the passage of time can be
    problematic on record development. See Moore v. Knight, 
    368 F.3d 936
    ,
    941–42 (7th Cir. 2004) (“[I]t is ridiculous to base such a determination [of
    whether or not there was prejudice] on the predictable lack of evidence so
    many years after the fact.”).      Because of the barriers presented by
    evidentiary rules, and often by the passage of time, questions of what
    presumptions and burdens of proof apply under various circumstances
    are critical to case outcomes when assessing whether extraneous
    influences prevented the defendant from receiving a fair trial.
    And there is a further complication, namely, the era of the Internet.
    Because of the Internet, the likelihood of jurors receiving extraneous
    information has exponentially increased.          See Bennett L. Gershman,
    Contaminating the Verdict: The Problem of Juror Misconduct, 
    50 S.D. L
    . Rev.
    322, 324 (2005). In June 2013, Wikipedia had almost eight billion page
    views. Anna H. Tison, United States v. Lawson: Problems with Presumption
    in the Fourth Circuit, 
    91 N.C. L
    . Rev. 2244, 2244 (2013). A low threshold
    for court intervention could significantly impact the stability of verdicts.
    36
    In the end, it would be difficult to argue that verdicts could never be
    impeached as a result of injection of extraneous information into the jury
    process. On the other hand, setting the bar too low could well backfire
    and could impose unacceptable costs that are at best weakly linked to trial
    outcomes. As is often the case in the law, it is a delicate balance.
    2. Competing approaches to extraneous influences on jurors in
    United States Supreme Court caselaw. We begin with a discussion of a
    thread of four United States Supreme Court cases dealing with the right
    to an impartial jury. As will be seen, the cases are at least somewhat
    inconsistent and have led to a variety of permutations in the lower federal
    courts.
    The first significant case is the capital murder case of Mattox v.
    United States, 
    146 U.S. 140
    , 
    13 S. Ct. 50
    (1892).          In Mattox, jurors
    submitted affidavits posttrial indicating the bailiff had discussed the case
    with the jury and a newspaper article related to the case was read to the
    jury. 
    Id. at 142–43,
    13 S. Ct. at 51. The bailiff had told the jury that the
    deceased in the case was the defendant’s third victim. 
    Id. at 142,
    13 S. Ct.
    at 51. The newspaper article stated this was the defendant’s second trial,
    the evidence against him was “very strong,” and “friends of Mattox gave up
    all hope of any result but conviction.” 
    Id. at 143,
    13 S. Ct. at 51–52.
    The Mattox Court addressed the question of what evidence should
    be considered in impeaching the jury’s verdict. The Mattox Court stated
    that a member of the jury could testify on the question of the existence of
    any extraneous influence, although not as to how far that influence
    operated upon the juror’s mind. See 
    id. at 149,
    13 S. Ct. at 52–53. At
    least in capital cases, the Mattox Court declared that “[p]rivate
    communications, possibly prejudicial, between jurors and third persons .
    . . are absolutely forbidden, and invalidate the verdict, at least unless their
    37
    harmlessness is made to appear.” 
    Id. at 150,
    13 S. Ct. at 53. In support
    of   the     notion   that   extraneous    communications   were   “absolutely
    forbidden,” the Mattox Court cited state court cases from Michigan and
    Kansas. 
    Id. (citing State
    v. Snyder, 
    20 Kan. 306
    , 308–10 (1878); People v.
    Knapp, 
    3 N.W. 927
    , 929–31 (Mich. 1879)).          Although there were other
    bases for reversal, the unanimous Mattox Court made clear the extraneous
    influence introduced to the jury in this case would have been reversible
    error as well. 
    Id. at 151,
    13 S. Ct. at 53.
    The next case in the thread is Remmer, 
    347 U.S. 227
    , 
    74 S. Ct. 450
    ,
    decided more than fifty years after Mattox. In Remmer, the defendant was
    charged with, and convicted of, willful evasion of federal income taxes. 
    Id. at 22
    8, 74 S. Ct. at 450.         The defendant learned after trial that an
    unnamed person told the jury foreman that the foreman could profit by
    bringing in a verdict favorable to the defendant. 
    Id. at 22
    8, 74 S. Ct. at
    450–51. The juror reported the incident to the judge, who informed the
    prosecution but not the defense. 
    Id. at 22
    8, 74 S. Ct. at 451. The FBI
    then conducted an investigation and produced a report, which was
    considered by the judge and the prosecutors alone. 
    Id. The judge
    and
    prosecution again considered the matter without the defense and, in light
    of the FBI report, concluded that “the statement to the juror was made in
    jest.” 
    Id. After trial,
    the defendant moved for a new trial. 
    Id. His attorneys
    asserted that if they had known of the investigation, they would have
    moved for a mistrial and requested that the juror in question be replaced
    by an alternate juror. 
    Id. at 22
    8–29, 74 S. Ct. at 451. The district court,
    without holding a hearing, denied the motion, and the D.C. Circuit
    affirmed. 
    Id. at 22
    9, 74 S. Ct. at 451.
    38
    The Remmer Court, in a brief unanimous opinion by Justice Minton,
    vacated the appellate decision and remanded to the district court. 
    Id. at 230,
    74 S. Ct. at 451–52. In a criminal case, the Remmer Court noted that
    any private communication, contact, or tampering directly or
    indirectly, with a juror during a trial about the matter pending
    before the jury is, for obvious reasons, deemed presumptively
    prejudicial, if not made in pursuance of known rules of the
    court and the instructions and directions of the court made
    during the trial, with full knowledge of the parties.
    
    Id. at 22
    9, 74 S. Ct. at 451.     In connection with the presumption of
    prejudice, the Remmer Court stated, “The presumption is not conclusive,
    but the burden rests heavily upon the Government to establish, after
    notice to and hearing of the defendant, that such contact with the juror
    was harmless to the defendant.” 
    Id. The Remmer
    Court further emphasized that sending an FBI agent
    during a trial to investigate a juror concerning his conduct “is bound to
    impress the juror and is very apt to do so unduly.” 
    Id. The Remmer
    Court
    stressed that a juror must be free to participate in deliberations “without
    the F.B.I. or anyone else looking over his [or her] shoulder.” 
    Id. In this
    noncapital case, the Supreme Court did not use the absolute
    terms of Mattox but instead established a rebuttable presumption that
    could be overcome by the state only on a showing that the extraneous
    influence was harmless. 
    Id. The Remmer
    Court directed the district court
    to hold a hearing on harm to the defendant and explained that if harm was
    found the district court should grant a new trial. 
    Id. at 230,
    74 S. Ct. at
    451–52.   When the case returned, the Court reviewed the transcript
    developed in the district court on remand, concluded that the juror
    appeared to be under psychological pressure due to the bribe offer, and
    remanded for a new trial. Remmer v. United States, 
    350 U.S. 377
    , 381–82,
    
    76 S. Ct. 425
    , 427–28 (1956).
    39
    Thirty years after Remmer, the United States Supreme Court
    considered a question of juror bias in the case of Smith v. Phillips, 
    455 U.S. 209
    , 
    102 S. Ct. 940
    (1982). Phillips was convicted of two counts of murder
    and one count of attempted murder. 
    Id. at 210,
    102 S. Ct. at 942. He
    learned that during trial a juror was an active job applicant for a position
    as a major felony investigator with the district attorney’s office. 
    Id. at 212,
    102 S. Ct. at 943. Members of the district attorney’s office, including the
    two attorneys actually prosecuting Phillips, learned of the application more
    than a week before the end of Phillips’s trial but elected not to advise the
    court or the defendant. 
    Id. at 212–13,
    102 S. Ct. at 943–44. After trial,
    the district attorney learned of the application and informed the court and
    defense attorneys. 
    Id. at 213,
    102 S. Ct. at 944.
    Upon learning of the juror’s employment application, the defendant
    moved to set aside the verdict. 
    Id. The trial
    court denied the motion,
    finding that while the application was an “indiscretion,” it “in no way
    reflected a premature conclusion as to [Phillips’s] guilt, or prejudice
    against [Phillips], or an inability to consider the guilt or innocence of
    [Phillips] solely on the evidence.” 
    Id. at 213–14,
    102 S. Ct. at 944.
    Phillips sought federal habeas corpus relief. 
    Id. at 214,
    102 S. Ct.
    at 944. The district court imputed bias to the juror because “the average
    [person] in [the juror’s] position would believe that the verdict of the jury
    would directly affect the evaluation of his job application.” 
    Id. (quoting Phillips
    v. Smith, 
    485 F. Supp. 1365
    , 1371–72 (S.D.N.Y. 1980)).            The
    district court decreed that Phillips should be released unless granted a
    new trial within ninety days. 
    Id. The Second
    Circuit affirmed by a divided
    vote, noting that “it is at best difficult and perhaps impossible to learn
    from a juror’s own testimony after the verdict whether he was in fact
    ‘impartial.’ ” 
    Id. (quoting Phillips
    v. Smith, 
    632 F.2d 1019
    , 1022 (2d Cir.
    40
    1980)). The Second Circuit relied on the failure of the prosecutors to timely
    disclose the potential problem as violating due process in reversing the
    conviction. 
    Id. Before the
    Supreme Court, Phillips argued that the Court could not
    possibly rely solely upon the testimony of the juror in question. 
    Id. at 215,
    102 S. Ct. at 945. The defendant argued that it would be impossible for
    him to prove the degree of bias through a Remmer-type hearing and that
    a conclusive presumption should arise under the facts of the case. 
    Id. In an
    opinion by Justice Rehnquist, a divided Supreme Court
    rejected the notion that the juror’s employment application itself was
    sufficient to establish the basis for a new trial. See 
    id. at 217,
    102 S. Ct.
    at 946. Instead, the majority held the proper approach was a Remmer-
    type hearing “in which the defendant has the opportunity to prove actual
    bias.” 
    Id. at 215,
    102 S. Ct. at 945. The Phillips majority, therefore, may
    have suggested it was departing from Remmer both on the issue of
    presumption and the harmless error standard required to overcome the
    presumption.
    In a concurring opinion, Justice O’Connor noted that “whether a
    juror is biased or has prejudged a case is difficult, partly because the juror
    may have an interest in concealing his own bias and partly because the
    juror may be unaware of it.” 
    Id. at 22
    1–22, 102 S. Ct. at 948 (O’Connor,
    J., concurring). Nonetheless, in most cases, Justice O’Connor concluded
    that a posttrial hearing would be adequate to determine whether a juror is
    biased. 
    Id. at 22
    2, 102 S. Ct. at 948. Yet, Justice O’Connor recognized
    that in some instances the use of a conclusive presumption might be
    justified. 
    Id. Justice Marshall,
    joined by Justices Brennan and Stevens,
    dissented. 
    Id. at 22
    4, 102 S. Ct. at 949 (Marshall, J., dissenting). Justice
    41
    Marshall emphasized that “[t]he right to a trial by an impartial jury lies at
    the very heart of due process.” 
    Id. at 22
    4, 102 S. Ct. at 950. In his view,
    the majority erred in concluding that Phillips’s right to an impartial trial
    was adequately protected by a postevidentiary hearing to determine
    whether the jury was actually biased.       
    Id. at 22
    8, 102 S. Ct. at 952.
    According to Justice Marshall, the probability of bias in the case arising
    from pursuit of employment was high yet it would be very difficult to prove
    the bias in a posttrial hearing. 
    Id. at 230,
    102 S. Ct. at 953. Justice
    Marshall cited precedent for the proposition that “[b]ias or prejudice is
    such an elusive condition of the mind that it is most difficult, if not
    impossible, to always recognize its existence.” 
    Id. at 231,
    102 S. Ct. at 953
    (quoting Crawford v. United States, 
    212 U.S. 183
    , 196, 
    29 S. Ct. 260
    , 265
    (1909)). Justice Marshall asserted that when the probability of bias is very
    high, a juror should be “automatically disqualified, despite the absence of
    proof of actual bias.” 
    Id. The last
    United States Supreme Court case is United States v. Olano,
    
    507 U.S. 725
    , 
    113 S. Ct. 1770
    (1993). In this case, the defendants were
    convicted of crimes related to a loan kickback scheme. 
    Id. at 727–29,
    113
    S. Ct. at 1774–75. In Olano, alternates were permitted to sit in the jury
    room during deliberations but were instructed not to participate. 
    Id. The question
    in Olano was whether the presence of the alternates during jury
    deliberations was “plain error” subject to correction under Federal Rule of
    Criminal Procedure 52(b). 
    Id. at 727,
    113 S. Ct. at 1774.
    In an opinion by Justice O’Connor, the Olano Court concluded that
    plain error under rule 52(b) was not present. 
    Id. at 737,
    113 S. Ct. at
    1779. The majority emphasized that in order to qualify under the rule, the
    error must be of a kind that “affects substantial rights” of the party. 
    Id. In order
    to so qualify, the Olano Court declared that the error must
    42
    “seriously affect[] the fairness, integrity or public reputation of judicial
    proceedings.” 
    Id. at 732,
    113 S. Ct. at 1776, (quoting United States v.
    Young, 
    470 U.S. 1
    , 15, 
    105 S. Ct. 1038
    , 1046 (1985)).
    The Olano Court concluded that no such violation of the defendant’s
    rights occurred by the mere presence of alternate jurors in the jury room.
    
    Id. at 737,
    113 S. Ct. at 1779. The Olano Court recognized there might be
    situations in which an intrusion into the jury room could be presumed
    prejudicial, but even in these cases, the ultimate inquiry continues to be
    whether the intrusion affected the jury’s deliberation and thereby its
    verdict. 
    Id. at 739,
    113 S. Ct. at 1780. Under the posture of the case, the
    Olano Court declined to find the mere presence of alternate jurors
    prejudicial. 
    Id. at 740–41,
    113 S. Ct. at 1781.
    Justice Stevens, joined by Justices White and Blackmun, dissented.
    
    Id. at 743,
    113 S. Ct. at 1782 (Stevens, J., dissenting). Justice Stevens
    argued,
    [S]ome defects bearing on the jury’s deliberative function are
    subject to reversal regardless of whether prejudice can be
    shown, not only because it is so difficult to measure their
    effects on a jury’s decision, but also because such defects
    “undermin[e] the structural integrity of the criminal tribunal
    itself.”
    
    Id. at 743,
    113 S. Ct. at 1782–83 (alteration in original) (quoting Vasquez
    v. Hillery, 
    474 U.S. 254
    , 263–64, 
    106 S. Ct. 617
    , 623 (1986)). Justice
    Stevens declared that if a proper objection had been made, reversal would
    have been required. 
    Id. at 744,
    113 S. Ct. at 1783. Because no objection
    was made in the case, however, Justice Stevens framed the issue as
    whether the court of appeals’ reversal of Olano’s conviction was an abuse
    of discretion. 
    Id. at 745,
    113 S. Ct. at 1783. Justice Stevens concluded
    that it was not. 
    Id. at 745,
    113 S. Ct. at 1784.

    3. Caselaw in lower federal courts.        In light of the different
    approaches in the United States Supreme Court cases, it is not surprising
    that the lower federal courts have adopted different approaches to juror
    misconduct and bias and, in particular, the continued viability of the
    Remmer principles. Below we review how the federal courts have dealt
    with aspects of Remmer. First, we consider whether a presumption of
    prejudice occurs in cases involving extraneous influences on jurors.
    Second, we review how the federal courts handle the prejudice issue.
    The caselaw on the question of whether to apply a Remmer-type
    presumption of prejudice in this field is nuanced and often fact-specific.
    Generally, however, as noted in United States v. Lawson, 
    677 F.3d 629
    ,
    643 (4th Cir. 2012), it appears that the Second, Fourth, Seventh, Ninth,
    Tenth, and Eleventh Circuits continue to apply the Remmer presumption
    of prejudice in at least some cases involving external influences on jurors.
    See 
    Godoy, 861 F.3d at 964
    n.3; United States v. Moore, 
    641 F.3d 812
    , 828
    (7th Cir. 2011); United States v. Ronda, 
    455 F.3d 1273
    , 1299 (11th Cir.
    2006); United States v. Greer, 
    285 F.3d 158
    , 173 (2d Cir. 2000); Mayhue v.
    St. Francis Hosp. of Wichita, Inc., 
    969 F.2d 919
    , 922–23 (10th Cir. 1992).
    Several circuits apply Remmer in some circumstances involving
    external influences on jurors. For instance, in United States v. Bradshaw,
    
    281 F.3d 278
    , 287–88 (1st Cir. 2002) (quoting United States v. Boylan, 
    898 F.2d 230
    , 261 (1st Cir. 1990)), the First Circuit stated that the Remmer
    presumption “is applicable only where there is an egregious tampering or
    third party communication which directly injects itself into the jury
    process.” In United States v. Lloyd, 
    269 F.3d 228
    , 238 (3d Cir. 2001), the
    Third Circuit applied the Remmer presumption of prejudice when a jury is
    exposed to extraneous information “of a considerably serious nature.” In
    another case, Stephens v. South Atlantic Canners, Inc. (Coca Cola Co.), 848
    
    44 F.2d 484
    , 486 (4th Cir. 1988) (quoting Haley v. Blue Ridge Transfer Co.,
    
    802 F.2d 1532
    , 1537 n.9 (4th Cir. 1986)), the Fourth Circuit noted that
    the Remmer presumption was applicable for “more than innocuous
    interventions.”
    In contrast, the Fifth, Sixth, Eighth, and District of Columbia
    Circuits seem to follow the approaches of Smith and Olano and do not
    employ a presumption of prejudice. See United States v. Sylvester, 
    143 F.3d 923
    , 933–35 (5th Cir. 1998); 
    Williams-Davis, 90 F.3d at 495
    –97;
    United States v. Blumeyer, 
    62 F.3d 1013
    , 1017 (8th Cir. 1995); United
    States v. Pennell, 
    737 F.2d 521
    , 532 (6th Cir. 1984).
    There is an additional question addressed in the federal cases
    besides the issue of whether a Remmer presumption is available. The
    federal cases also address the question of how to determine prejudice
    which might rebut a presumption, if one is available, or which might
    otherwise be part of a defendant’s burden in establishing a basis for
    mistrial or obtaining a new trial.
    In Remmer, the burden of proof rested with the government. There
    is authority suggesting that the burden of proof remains with the
    government in some circumstances, particularly in jurisdictions that
    continue to apply the Remmer presumption. See 
    Cheek, 94 F.3d at 141
    (explaining that extrajudicial comments shift burden of proof to
    government); United States v. Ruggiero, 
    56 F.3d 647
    , 652 (5th Cir. 1995)
    (explaining that government has the burden of showing harmlessness);
    United States v. Scisum, 
    32 F.3d 1479
    , 1484 (10th Cir. 1994) (holding that
    government failed to meet its heavy burden of showing harmlessness);
    United States v. Perkins, 
    748 F.2d 1519
    , 1533 (11th Cir. 1984) (“Prejudice
    from extrinsic evidence is assumed in the form of a rebuttable presumption
    and the government bears the burden of demonstrating that the
    45
    consideration of the evidence was harmless.”). However, in some circuits
    taking the view that Remmer was largely abandoned in Smith and Olano,
    the burden remains with the defendant. See, e.g., 
    Pennell, 737 F.2d at 532
    .
    Many federal courts have characterized the general question as
    being whether there is a “reasonable possibility” that the extrinsic material
    influenced the verdict. See, e.g., 
    Cheek, 94 F.3d at 138
    ; United States v.
    Maree, 
    934 F.2d 196
    , 201–02 (9th Cir. 1991), abrogated on other grounds
    by United States v. Adams, 
    432 F.3d 1092
    , 1095 (9th Cir. 2006); United
    States v. Rowe, 
    906 F.2d 654
    , 656–57 (11th Cir. 1990); Dickson v. Sullivan,
    
    849 F.2d 403
    , 404 (9th Cir. 1988). Other federal courts have suggested
    that “substantial likelihood of prejudice” is the proper test.        See, e.g.,
    
    Lloyd, 269 F.3d at 243
    .
    In any event, it is clear that “[t]here is no bright line test for
    determining whether a defendant has suffered prejudice from an instance
    of juror misconduct.” Sassounian v. Roe, 
    230 F.3d 1097
    , 1109 (9th Cir.
    2000) (quoting Rodriguez v. Marshall, 
    125 F.3d 739
    , 744 (9th Cir. 1997),
    overruled in part on other grounds by Payton v. Woodford, 
    299 F.3d 815
    ,
    827–29 & n.11 (9th Cir. 2002)). A number of federal courts, however, have
    articulated a nonexclusive factor test to aid courts in determining the issue
    of prejudice. For example, the Ninth Circuit has suggested that factors
    relevant to the prejudice inquiry include
    (1) whether the material was actually received, and if so, how;
    (2) the length of time it was available to the jury; (3) the extent
    to which the juror discussed and considered it; (4) whether
    the material was introduced before a verdict was reached, and
    if so at what point in the deliberations; and (5) any other
    matters which may bear on the issue of the reasonable
    possibility of whether the extrinsic material affected the
    verdict.
    46
    
    Dickson, 849 F.2d at 406
    (quoting Marino v. Vasquez, 
    812 F.2d 499
    , 506
    (9th Cir. 1987)).      Other cases have also articulated multifactor
    formulations to guide courts in determining the prejudice issue.          See
    
    Lloyd, 269 F.3d at 239
    –41 (identifying as factors the relationship of
    extraneous information to jury’s findings, extent of the jury’s exposure,
    timing of the jury’s receipt of the extraneous information, length and
    structure of jury deliberations, and content of jury instructions).
    Most lower federal courts have emphasized that the determination
    of prejudice is an objective inquiry. For example, in 
    Greer, 285 F.3d at 173
    , the Second Circuit embraced Remmer in a case involving extra-record
    information.   In determining whether the extra-record information was
    harmless, the court emphasized that the determination was an objective
    one based upon the probable effect on a “hypothetical average juror.” 
    Id. (quoting United
    States v. Calbas, 
    821 F.2d 887
    , 896 n.9 (2d Cir. 1987)).
    The Greer court emphasized that it would be improper for a district court
    to inquire into, or admit affidavits concerning, whether the extra-record
    information had an impact on a juror or the jury. Id.; see also 
    Lloyd, 269 F.3d at 237
    –38 (emphasizing consideration of objective, not subjective,
    impact on hypothetical average juror); 
    Cheek, 94 F.3d at 143
    (holding the
    district court erred in relying on juror’s mental processes when
    formulating findings of fact); United States v. Howard, 
    506 F.2d 865
    , 869
    (5th Cir. 1975) (stating that on remand the district court must disregard
    affidavit purporting to reveal alleged influence of extrinsic matter and avoid
    examination concerning jurors’ mental processes). Cf. United States v.
    Armstrong, 
    654 F.2d 1328
    , 1333 n.2 (9th Cir. 1981) (“Even though courts
    must apply an objective test in evaluating juror influence questions
    because jurors may not testify about their deliberations, it was proper for
    47
    the District Court to consider juror Gingras’s statements in her note since
    they were before the court.” (Citation omitted.)).
    Several federal courts have considered whether the number of jurors
    who are aware of the external influence is material in the calculation of
    prejudice. In 
    Parker, 385 U.S. at 365
    –66, 87 S. Ct. at 471, the United
    States Supreme Court stated that due process is violated if one juror is
    improperly influenced. Following the Supreme Court’s lead, the federal
    caselaw suggests that the number of jurors who heard or were aware of
    the external influence does not weigh heavily in the analysis. See, e.g.,
    Dyer v. Calderon, 
    151 F.3d 970
    , 973 (9th Cir. 1998) (“The bias or prejudice
    of even a single juror would violate Dyer’s right to a fair trial.”); Lawson v.
    Borg, 
    60 F.3d 608
    , 613 (9th Cir. 1995) (“The number of jurors affected by
    the misconduct does not weigh heavily in the prejudice calculus for even
    a single juror’s improperly influenced vote deprives the defendant of an
    unprejudiced, unanimous verdict.”); United States v. Delaney, 
    732 F.2d 639
    , 643 (8th Cir. 1984) (“If a single juror is improperly influenced, the
    verdict is as unfair as if all were.” (quoting Stone v. United States, 
    113 F.2d 70
    , 77 (6th Cir. 1940))); Tillman v. United States, 
    406 F.2d 930
    , 937 (5th
    Cir. 1969) (“[I]f only one juror is improperly influenced, the trial is as unfair
    as if every juror was so influenced.”), vacated on other grounds, 
    395 U.S. 830
    , 
    89 S. Ct. 2143
    (1969) (per curiam). But see 
    Lloyd, 269 F.3d at 240
    (stating that the extent to which jury is exposed to extraneous information
    is a factor in determining prejudice).
    4. Caselaw in other states.        The caselaw in the states on the
    question of how to handle extraneous influences on juries is varied. For
    instance, in Georgia, a Remmer-type presumption applies not only to
    extraneous influences but to any type of irregular juror conduct. Holcomb
    v. State, 
    485 S.E.2d 192
    , 195 (Ga. 1997). The Georgia caselaw, however,
    48
    distinguishes between inconsequential and irregular conduct. Lamons v.
    State, 
    340 S.E.2d 183
    , 184 (Ga. 1986) (“[S]ome irregularities are
    inconsequential.”). See generally Rachel Morelli, Comment, The Connected
    Juror’s Effect on the Sixth Amendment Right to an Impartial Jury and
    Georgia’s Presumption of Prejudice, 7 J. Marshall L.J. 527, 529 (2014)
    (discussing presumption of harm to defendant whenever there is irregular
    juror conduct).    Similarly, the Connecticut Supreme Court concluded
    recently that the Remmer-type presumption remains good law in a jury
    tampering case. State v. Berrios, 
    129 A.3d 696
    , 712 (Conn. 2016).
    Like the federal courts, state law cases that follow Remmer tend to
    leave the burden of proof with the state. See, e.g., 
    id. at 713.
    In State v.
    Stafford, 
    678 P.2d 644
    , 647 (Mont. 1984), however, the Montana Supreme
    Court placed the burden on the defendant to show prejudice from a letter
    circulated to the jury urging the jury to resist court instructions. Similarly,
    in Massey v. State, 
    541 A.2d 1254
    , 1259 (Del. 1988), the Delaware
    Supreme Court placed the burden of showing actual prejudice on the
    defendant     unless    there    are    inherently    prejudicial   egregious
    circumstances.
    Some state cases embrace the reasonable-possibility test.            For
    instance, in Wiser v. People, 
    732 P.2d 1139
    , 1142 (Colo. 1987) (en banc),
    the Colorado Supreme Court stated that the test was “whether there is a
    ‘reasonable possibility’ that extraneous contact or influence affected the
    verdict to the detriment of the defendant.”       The Wiser court collected
    federal and state cases to the same effect. 
    Id. Later, in
    People v. Wadle,
    
    97 P.3d 932
    , 937 (Colo. 2004) (en banc), the Colorado court applied the
    reasonable possibility test.
    In contrast, the New Mexico Supreme Court recently overhauled its
    approach to handling cases in which jurors receive extraneous material in
    49
    Kilgore v. Fuji Heavy Industries Ltd., 
    240 P.3d 648
    , 656 (N.M. 2010). The
    Kilgore court abandoned the notion of presumption of prejudice for a new
    approach. 
    Id. Under Kilgore,
    the proper inquiry is whether “there is a
    reasonable probability that the extraneous material affected the verdict or
    a typical juror.”   
    Id. The Kilgore
    court stated that whether there is a
    reasonable probability that the extraneous material affected the jury
    included consideration of five factors:
    1. The manner in which the extraneous material was
    received;
    2. How long the extraneous material was available to the jury;
    3. Whether the jury received the extraneous material before
    or after the verdict;
    4. If received before the verdict, at what point in the
    deliberations was the material received; and
    5. Whether it is probable that the extraneous material
    affected the jury’s verdict, given the overall strength of the
    opposing party’s case.
    Id.; see also In re Hamilton, 
    975 P.2d 600
    , 614 (Cal. 1999) (embracing
    “probability of prejudice” test); Commonwealth v. Sneed, 
    45 A.3d 1096
    ,
    1115 (Pa. 2012) (embracing “reasonable likelihood of prejudice” test
    (quoting Carter ex rel. Carter v. U.S. Steel Corp., 
    604 A.2d 1010
    , 1016 (Pa.
    1992))).
    State courts have used an objective test for evaluating claims of jury
    misconduct. In 
    Wiser, 732 P.2d at 1142
    , the Colorado Supreme Court
    employed an objective test to determine what effect misconduct would
    have on a typical jury. Similarly, in Buchholz v. State, 
    366 N.W.2d 834
    ,
    840 (S.D. 1985), the South Dakota Supreme Court emphasized that the
    inquiry must apply an objective test and focus on the effect of the
    extraneous information on a typical juror.
    50
    5. Iowa caselaw. Iowa caselaw has long been reluctant to set aside
    jury verdicts on grounds of jury misconduct.         Our traditional cases
    emphasize that in order for a new trial to be granted based on jury
    misconduct, it must be shown that the misconduct influenced the jury in
    reaching its verdict. See State v. Jackson, 
    195 N.W.2d 687
    , 689 (Iowa
    1972) (collecting cases).
    A case with a somewhat unusual posture is Carey, 
    165 N.W.2d 27
    .
    In that case, the defendant was convicted of the crime of aggravated
    burglary. 
    Id. at 28.
    In Carey, coffee was provided in the jury room with a
    typewritten sign indicating it was furnished by the county clerk and the
    county attorney. 
    Id. The defendant
    moved for a mistrial, which the district
    court denied. 
    Id. at 28–29.
    We found the practice would lessen public
    confidence in our judicial system and declared it “fraught with danger, one
    that is calculated to bring the administration of justice into disrepute, and
    one which all courts should zealously guard against.” 
    Id. at 30.
    In light of other trial errors, however, we were not required to
    determine whether reversal would be appropriate based on the issue. 
    Id. More than
    a decade later, however, we decided Omaha Bank for
    Cooperatives v. Siouxland Cattle Cooperative, 
    305 N.W.2d 458
    (Iowa 1981).
    In this case, we reversed a civil judgment after a jury foreman spoke to
    defense lawyers, made an offer to buy them drinks which was accepted,
    and engaged in extended conversation. 
    Id. at 461–62.
    We found in Omaha
    Bank there was not sufficient evidence to support a finding that the
    contact was not prejudicial to the adverse party. 
    Id. at 462.
    After Carey and Omaha Bank, we considered a first-degree murder
    case in which the defendant sought a new trial based upon jury
    irregularity in 
    Cullen, 357 N.W.2d at 25
    . In this case, three jurors advised
    the court, in front of the other jurors, that they knew one of the rebuttal
    51
    witnesses and that “they absolutely would not have served had they known
    these witnesses would be called to testify.” 
    Id. at 26.
    The district court
    granted the mistrial, noting that juror statements made it easier for other
    jurors to believe the rebuttal witnesses. 
    Id. at 26–27.
    In granting the relief,
    the district court relied on language in Carey, emphasizing that jury
    deliberations and pronouncements must be free “not only from all
    improper influences, but from the appearance thereof.”          See 
    id. at 27
    (quoting 
    Carey, 165 N.W.2d at 30
    ).
    The Cullen court reversed. In doing so, it found that our precedents
    established that in order to impeach a verdict, a three-pronged test must
    be met: (1) evidence must consist only of objective evidence, (2) the acts or
    statements must exceed tolerable bounds of jury deliberation, and (3) the
    misconduct must appear calculated to, and with reasonable probability
    did, influence the verdict. 
    Id. The Cullen
    court also considered the question of prejudice.          The
    Cullen court rejected the district court’s approach that the “possibility”
    jurors would be unable to give appropriate weight to the testimony of
    rebuttal witnesses was sufficient for reversal.       
    Id. at 28.
       The court
    emphasized that there must be a reasonable probability the verdict be
    influenced, a test that the court declared “is not easy to satisfy.” 
    Id. Importantly, the
    Cullen court noted that Carey was inapposite
    because it dealt with a distinct issue. 
    Id. The Cullen
    court emphasized
    the distinction between manipulation of the jury by outsiders, as in Carey,
    and cases concerned only with the internal operation of the jury. 
    Id. The Cullen
    court stated that in the case of manipulation of the jury by
    outsiders, a stricter rule is justified to keep the jury above suspicion. 
    Id. The Cullen
    court did not indicate what that stricter rule might be. Still,
    52
    the plain suggestion is the three-pronged Cullen approach might not apply
    to outside efforts to manipulate the jury. 
    Id. In at
    least one case decided after Cullen, however, we rejected the
    notion that introduction of extraneous evidence gave rise to a presumption
    of prejudice.   In Doe v. Johnston, 
    476 N.W.2d 28
    , 34 (Iowa 1991), we
    considered whether the circulation of a cartoon about the case in the jury
    room provided grounds for a new trial. The cartoon depicted a judge telling
    the jury, “The verdict should be guilty or not guilty. There’s no provision
    for guiltyish.” 
    Id. In Johnston,
    we first held that jurors were incompetent to testify
    about the impact of the cartoon on their verdict. 
    Id. The Johnston
    court
    stated, “When there is proof that extraneous material has reached the jury
    room, the party seeking reversal on a misconduct claim must prove ‘that
    the misconduct was calculated to, and with reasonable probability did,
    influence the verdict.’ ” 
    Id. at 35
    (quoting 
    Johnson, 445 N.W.2d at 342
    ).
    The Johnston court cited with approval a federal case emphasizing that the
    court’s task was to determine whether extraneous information would
    prejudice an “objective, ‘typical juror.’ ” 
    Id. (citing Urseth
    v. City of Dayton,
    
    680 F. Supp. 1084
    , 1089 (S.D. Ohio 1987)).
    In Johnston, we rejected a claim that “prejudice is presumed to
    result from the introduction of extraneous information.” 
    Id. We noted
    that
    some leeway was required in order to prevent a relatively minor matter
    from disrupting what might be a lengthy, costly, and otherwise fair trial.
    
    Id. On the
    facts, we concluded that injection of a humorous cartoon would
    not prompt an objective juror to reverse his or her view after days of
    testimony and jury deliberation. 
    Id. The Johnston
    discussion, however,
    seems to suggest that we were rejecting presumption of prejudice where
    the intrusion into the jury was minimal.
    53
    In the recent case of Webster, the defendant challenged a district
    court’s denial of a posttrial motion for a new 
    trial. 865 N.W.2d at 226
    . In
    Webster, the conduct of a juror was challenged on grounds that the juror
    was less than candid during voir dire about her relationship with the
    victim’s family, engaged in a brief trial-related communication with a third
    party at a convenience store during the trial, impermissibly engaged in
    outside-the-record research on the age of one of the witnesses, and
    improperly clicked “like” on a Facebook comment in which the victim’s
    stepmother stated “Give me strength.” 
    Id. at 234–35.
    The defendant failed to preserve constitutional error in this case. 
    Id. at 232.
    Webster asserted that review was for abuse of discretion. 
    Id. at 233.
    In light of the advocacy, we stated that our review of jury misconduct
    was for abuse of discretion, but observed in a footnote that we did not
    address the question of whether de novo review would be appropriate if
    constitutional issues were involved. 
    Id. at 231
    & n.4. With respect to the
    legal standard to be applied to juror misconduct and juror bias, Webster
    asked us to apply the standard articulated in 
    Cullen, 357 N.W.2d at 27
    .
    865 N.W.2d at 234. We were thus not asked to consider the implications
    of Remmer and its progeny or the approach in Carey. We did not explore
    adopting these standards that no one asked us to consider.
    In Webster, we rejected the claims of juror misconduct by
    conducting a factual review in which the standard of review and even the
    substantive legal standards were largely irrelevant. See 
    id. at 235–41.
    We
    concluded the juror did not provide false testimony in voir dire about her
    relationship with the victim’s family, the juror basically dusted off an
    interloper at a brief stop at a convenience store, the outside-the-record
    research occurred after the verdict was rendered, and the clicking of “like”
    on Facebook, though reflecting bad judgment, reflected empathy for the
    54
    stepmother who lost her son and did not relate to the guilt or innocence of
    the accused. 
    Id. In Webster,
    however, we cautioned that jurors are now part of the
    electronic world and that there was a risk that jurors could engage in
    electronic and social media activity during trial. 
    Id. at 239–40.
    We urged
    district courts to give admonitions explicitly prohibiting electronic
    communications “early and often” in the course of a trial. 
    Id. at 240–41.
    D. Application of Jury Misconduct Principles to this Case.
    1. Proper standard for appellate review.       We first address the
    question of the proper standard of review in this case. The parties dispute
    whether the standard of review should be de novo or for abuse of
    discretion.
    When a party seeks a mistrial under our rules designed to ensure a
    fair trial, but does not mention any provision of the Iowa or United States
    Constitution, we have not yet decided whether the proper approach is
    de novo review. In Webster, we reserved the question for another day in
    light of our general agreement with the fact-finding of the district court.
    
    Id. at 231
    n.4.
    We have broadly stated many times and in many contexts that when
    constitutional issues are involved, the standard of appellate review of fact-
    finding by the district court is de novo. See, e.g., State v. Green, 
    896 N.W.2d 770
    , 775 (Iowa 2017) (jury instruction impacting constitutional
    rights); State v. Kennedy, 
    846 N.W.2d 517
    , 520 (Iowa 2014) (Confrontation
    Clauses under Federal and Iowa Constitutions); Gartner v. Iowa Dep’t of
    Pub. Health, 
    830 N.W.2d 335
    , 344 (Iowa 2013) (constitutionality of statutes
    or administrative rule); State v. Mootz, 
    808 N.W.2d 207
    , 214 (Iowa 2012)
    (state and federal equal protection in context of Batson challenge); State v.
    Decker, 
    744 N.W.2d 346
    , 353 (Iowa 2008) (Iowa due process and Fifth
    55
    Amendment right to counsel in custodial interrogation); State v.
    Leutfaimany, 
    585 N.W.2d 200
    , 203 (Iowa 1998) (Iowa due process and
    Fifth Amendment right to a fair trial); State v. Morgan, 
    559 N.W.2d 603
    ,
    606 (Iowa 1997) (uncounseled and coerced guilty plea); State v. Dawdy,
    
    533 N.W.2d 551
    , 553 (Iowa 1995) (search and seizure); State v. Schultzen,
    
    522 N.W.2d 833
    , 835–36 (Iowa 1994) (right to public trial). De novo review
    of constitutional issues is necessary because constitutional rules “acquire
    content only through application” and “[i]ndependent review is therefore
    necessary if appellate courts are to maintain control of, and to clarify, the
    legal principles.” Ornelas v. United States, 
    517 U.S. 690
    , 697, 
    116 S. Ct. 1657
    , 1662 (1996). Further, de novo review of constitutional issues “tends
    to unify precedent” and thus provides better insight into whether a
    particular circumstance constitutes a constitutional violation. 
    Id. The rules
    implicated in this case are designed to implement the
    constitutional demands of due process. If claims alleging violation of a
    constitutional right merit de novo review, the same reasons suggest
    de novo review may be appropriate for claims involving rules implementing
    constitutional rights. Mere incantation of constitutional phrases need not
    control our standard of review.
    Still, in prior cases, we have reviewed with deference decisions on
    claims raised under the rules of criminal procedure. For instance, as the
    State points out, in State v. McNeal, 
    897 N.W.2d 697
    , 703 (Iowa 2017),
    “[w]e review[ed] a district court’s application of the procedural rules
    governing speedy trial for correction of errors at law” and “[w]e review[ed]
    a district court’s determination whether the State carried its burden to
    show good cause for the delay for abuse of discretion.” In another case
    cited by the State, State v. Clark, 
    464 N.W.2d 861
    , 864 (Iowa 1991), we
    reviewed a challenge to a district court’s refusal to grant separate trials
    56
    under our rules of criminal procedure and explained that “[w]e will reverse
    a trial court’s refusal to grant a motion for separate trials only if a
    defendant demonstrates an abuse of discretion.” Yet in neither case did
    the parties challenge the standard of review; in both cases the parties
    agreed a deferential standard of review applied. See Brief for Appellant at
    25–26, State v. McNeal, 
    897 N.W.2d 697
    (Iowa 2017) (No. 15–1606); Brief
    for Appellee at 14, State v. McNeal, 
    897 N.W.2d 697
    (Iowa 2017) (No. 15–
    1606); Brief for Appellant at 13, State v. Clark, 
    464 N.W.2d 861
    (Iowa 1991)
    (No. 89–1355); Brief for Appellee at 8, State v. Clark, 
    464 N.W.2d 861
    (Iowa
    1991) (No. 89–1355).
    In the context of jury misconduct and jury bias, a number of courts
    have seen fit to review ultimate determinations with less deference than
    ordinarily applied in motions for new trial. For instance, Judge Posner
    held,
    We review the district court’s findings of fact under the clearly
    erroneous standard. However, because the ultimate factual
    determination of impartiality depends on inferences of effect
    drawn from the subsidiary facts, we believe a more critical
    review of the district court’s ultimate finding of fact is
    appropriate in this context than in other situations.
    Owen v. Duckworth, 
    727 F.2d 643
    , 646 (7th Cir. 1984). The Fourth Circuit
    applies substantially the same standard:
    The final question is whether the improper contact or
    communication compromised the impartiality of the jury.
    Ordinarily, the grant of a new trial is committed to the sound
    discretion of the district court. However, because the ultimate
    factual determination regarding the impartiality of the jury
    necessarily depends on legal conclusions, it is reviewed in
    light of all the evidence under a “somewhat narrowed,”
    modified abuse of discretion standard giving the appellate
    court “more latitude to review the trial court’s conclusion in
    this context than in other situations.”
    
    Cheek, 94 F.3d at 140
    (citation omitted) (quoting 
    Haley, 802 F.2d at 1532
    ,
    1537 nn.11–12).
    57
    Other jurisdictions, however, afford more deference to a trial court’s
    determination.   In the Eighth Circuit, “[t]he district court has broad
    discretion in handling allegations of juror misconduct and its decision will
    be affirmed absent an abuse of discretion.” United States v. Williams, 
    77 F.3d 1098
    , 1100 (8th Cir. 1996). In Connecticut, allegations of juror bias
    or misconduct are reviewed for an abuse of discretion because “[a]ny
    assessment of the form and scope of the inquiry that a trial court must
    undertake when it is presented with [such] allegations . . . will necessarily
    be fact specific.” State v. Brown, 
    901 A.2d 86
    , 89 (Conn. App. Ct. 2006)
    (quoting State v. Sinvil, 
    876 A.2d 1237
    , 1245 (Conn. App. Ct. 2005)).
    We need not resolve this issue in this case. As in 
    Webster, 865 N.W.2d at 231
    n.4, we generally agree with the fact-finding of the district
    court. Therefore, the result in this case does not depend on the standard
    of review. This approach is consistent with State v. Martin, 
    877 N.W.2d 859
    , 865 n.4 (Iowa 2016), where we left for another day the question of
    whether claims under our rules designed to protect a defendant’s right to
    a fair trial give rise to de novo review when the defendant fails to make a
    constitutional claim.
    2. Presumption of prejudice. We must next determine whether there
    is an irrebuttable presumption of prejudice. We note Justice O’Connor’s
    concurring opinion in Phillips that under the Sixth Amendment there
    might be occasions where the facts are sufficiently egregious to require an
    irrebuttable 
    presumption. 455 U.S. at 222
    –24, 102 S. Ct. at 948–49
    (O’Connor, J., concurring). And we do not regard our Iowa caselaw as
    necessarily foreclosing an irrebuttable presumption in the appropriate
    circumstances. But we do not find the present case involving a relatively
    vague and unspecific rumor of a potential riot briefly discussed by jurors
    58
    sufficient to give rise to an irrebuttable presumption of the kind suggested
    by Justice O’Connor.
    Having concluded that there is no irrebuttable presumption of
    prejudice under the facts of this case, there remains the possibility of
    applying a rebuttable presumption as in Remmer, 347 U.S. at 
    229, 74 S. Ct. at 451
    , and as still applied by a majority of the federal courts. There
    is caselaw suggesting that this type of Remmer presumption is particularly
    appropriate in jury tampering cases. For instance, in 
    Dutkel, 192 F.3d at 894
    –95, 899, the Ninth Circuit suggested that in jury tampering cases, the
    Remmer presumption should apply and the state should have to meet a
    heavy burden to prove that the tampering was not prejudicial.
    Based on our review of the trajectory of the cases of the Supreme
    Court and the federal circuits, we believe that Remmer may have some
    remaining vitality under the Federal Constitution as a rebuttable
    presumption in certain circumstances. And of course, we can apply such
    a presumption under article I, sections 9 and 10 of the Iowa Constitution.
    In this case, however, we are not dealing with direct jury tampering or
    bribery efforts by third parties. Instead, we are dealing with jurors who
    learned about a vague and generalized report on social media that some
    unknown persons might engage in a riot related to the trial in question.
    Dutkel does not provide much aid to Christensen on the facts of this case.
    We agree with the courts taking the position that the Remmer-type
    presumption is for “more than innocuous interventions.” 
    Stephens, 848 F.2d at 486
    (quoting 
    Haley, 802 F.2d at 1537
    n.9); see 
    Lloyd, 269 F.3d at 238
    ; 
    Lamons, 340 S.E.2d at 184
    . While Remmer may have some remaining
    vitality under federal and state law, we do not think it applies to the facts
    of this case.
    59
    We also do not find that the principles in 
    Carey, 165 N.W.2d at 28
    –
    30, or Omaha 
    Bank, 305 N.W.2d at 461
    –62, are applicable in this case. It
    was poor judgment for the clerk and county attorney to post its message
    in the jury room that the coffee was being provided by 
    them. 165 N.W.2d at 30
    . Although hardly constituting a bribe of the kind that might sway
    juries, it did send an informal message that the county attorney and
    members of the jury were on the same team. See 
    id. The Carey
    court
    clearly wanted to send a contrary message that even this small
    accommodation from a party to litigation had no place in our court system
    where the appearance of fairness is extremely important. See 
    id. It is
    not
    at all clear that but for other trial errors, the Carey court would have
    reversed the conviction. See 
    id. In Omaha
    Bank, the challenged conduct involved a juror buying
    drinks for lawyers and having extended conversation with the lawyers in
    the midst of trial at a restaurant 
    bar. 305 N.W.2d at 461
    . The Omaha
    Bank court condemned the lawyers for attempting to ingratiate themselves
    to a juror by accepting drinks and engaging in extended conversation with
    the juror at the bar. 
    Id. at 461–63.
    In the case presently before us, there
    was no similar misconduct by a party or a party’s representatives.
    3. Requirements of prejudice.     On the question of prejudice, the
    caselaw is generally divided regarding the standard of prejudice required
    in extraneous influence cases. Many federal extraneous influence cases
    recite a possibility-of-prejudice test, while others embrace a more
    demanding reasonable-probability test. In Cullen, a case involving the
    internal workings of the jury, we adopted a higher reasonable-probability
    
    test. 357 N.W.2d at 27
    .    We have repeatedly applied the reasonable-
    probability test in a variety of settings. See, e.g., State v. Atwood, 
    602 N.W.2d 775
    , 778–80 (Iowa 1999) (holding that a judge’s communication of
    60
    threat made to all participants in the case, including the jury, is subject
    to a reasonable likelihood or reasonable probability of prejudice test); State
    v. Henning, 
    545 N.W.2d 322
    , 324–25 (Iowa 1996) (holding that extra-
    record information about defendant’s prior criminal offenses sufficiently
    prejudicial to meet reasonable-probability test). We apply the reasonable-
    probability test of Cullen today.
    We also note that our prior cases adopt the view that juror
    statements about the impact of the improperly introduced influence are
    not admissible on the question of prejudice. 
    Johnston, 476 N.W.2d at 34
    ;
    
    Carey, 165 N.W.2d at 30
    . What can be considered is objective facts—who
    said what to whom and when and what specifically was injected into the
    jury discussion. But juror assessments about the impact of the improper
    extraneous influence are off limits. 
    Johnston, 476 N.W.2d at 34
    ; 
    Carey, 165 N.W.2d at 30
    ; see also 
    Greer, 285 F.3d at 173
    ; 
    Calbas, 821 F.2d at 896
    n.9; 
    Wiser, 732 P.2d at 1142
    ; 
    Buchholz, 366 N.W.2d at 840
    .
    Finally, we recognize that in determining fair trial issues, one
    improperly influenced juror is sufficient to require reversal. 
    Parker, 385 U.S. at 365
    –66, 87 S. Ct. at 471; 
    Webster, 865 N.W.2d at 237
    n.7. We
    should not be distracted by a numbers game regarding how many jurors
    heard what and when they heard it. See, e.g., 
    Lawson, 60 F.3d at 613
    ;
    
    Delaney, 732 F.2d at 643
    ; 
    Tillman, 406 F.2d at 937
    . The issue instead
    should be focused on the question of whether any juror or jurors have
    been shown to be improperly influenced such that a conviction based on
    a verdict in which the juror or jurors participated simply cannot be upheld.
    4. Determination of prejudice issue. We focus our analysis on the
    question of prejudice. In doing so, we agree with the approach of courts
    that consider multiple factors in determining the question of prejudice.
    
    Lloyd, 269 F.3d at 240
    ;

    Based on our review of the record, we conclude that Christensen
    failed to show a reasonable probability that the verdict of the jury would
    have been different if the extraneous influence did not reach the jury in
    this case. 
    Cullen, 357 N.W.2d at 27
    . Here, the threat of a riot reported to
    the juror and the jury was vague, was not directed at any juror, and was
    merely a hearsay statement about what purportedly appeared in social
    media. Every reasonable juror knows that a wide variety of vacuous claims
    and statements may appear on social media without the slightest veracity.
    In addition, there was no objective support for the threat of a riot in the
    record except the vague hearsay report of a Facebook comment.
    There was evidence that the vague report to the jury about a
    Facebook posting mentioning a riot was only briefly discussed by the jury.
    There was no evidence of an extended discussion. See 
    Dickson, 849 F.2d at 406
    .   Further, though the discussion about a riot appears to have
    occurred prior to the jury actually reaching a verdict, the record suggests
    that the discussion likely may have occurred after the jury reached its
    verdict but prior to announcing it in open court.        See 
    id. There was
    certainly no persuasive specific evidence that the rumors of a potential riot
    were discussed at a critical stage in the jury’s deliberation. See 
    id. Finally, there
    was nothing extraordinary about the jury verdict of second-degree
    murder in this case, a verdict that was well within the evidence presented
    at trial. See 
    Kilgore, 240 P.3d at 656
    ; United States v. Sanders, 
    962 F.2d 660
    , 673 (7th Cir. 1992). There is no objective reason to consider the jury
    verdict as motivated by fear from a vague speculative hearsay report on
    Facebook about a possible riot.
    We recognize that at least some members of the jury did express
    concern about safety at the courthouse and asked for a police escort to
    their cars. Another asked for an officer to patrol the juror’s home. These
    62
    protective measures after a controversial trial show a degree of common
    sense but do not make a persuasive per se case that the jury’s verdict was
    likely influenced by the vague hearsay riot rumors. See State v. Napulou,
    
    936 P.2d 1297
    , 1304 (Haw. Ct. App. 1997).
    Although each case will turn on its specific facts, the result we reach
    here is not inconsistent with other caselaw. For instance, in Wallace v.
    United States, 
    412 F.2d 1097
    , 1102 (D.C. Cir. 1969), jurors were
    interviewed in chambers after a newspaper article detailed certain death
    threats against the jurors. The jurors’ responses convinced the district
    court that they could continue to serve as impartial jurors. 
    Id. Similarly, in
    Napulou, the court upheld a district court determination that a new trial
    was not required after the jurors felt intimidated upon being followed by
    the defendant’s family members, a setting far more troubling than that
    presented in this 
    case. 936 P.2d at 1304
    .
    Christensen cites two cases in which the potential for public violence
    led to a change in venue. 
    Powell, 283 Cal. Rptr. at 787
    ; 
    Lozano, 584 So. 2d at 22
    . We find these cases inapposite. They are pretrial change of venue
    cases in which there had been massive publicity and substantial threats
    of violence had arisen from the underlying incidents. We do not find them
    instructive on the case at hand.
    Based on the above reasoning, we conclude that Christensen has
    failed to meet the Cullen test of showing a reasonable probability that the
    jury would have come to a different conclusion if it had not received the
    vague and speculative extraneous information about a potential riot.
    E. Jury Bias. Christensen notes in passing that the district court
    erred in concluding that implied bias did not warrant a new trial.
    Christensen supports his claim of implied bias by pointing to the testimony
    of a juror claiming that two jurors saw Facebook posts threatening the
    63
    jurors themselves.     He also notes that the jurors were aware of the
    heightened community awareness surrounding the case.
    In 
    Webster, 865 N.W.2d at 236
    , we explained that juror bias may be
    actual or implied. “Actual juror bias occurs when the evidence shows that
    a juror, in fact, is unable to lay aside prejudices and judge a case fairly on
    the merits.” 
    Id. “Implied bias
    arises when the relationship of a prospective
    juror to a case is so troublesome that the law presumes a juror would not
    be impartial.” 
    Id. “Implied bias
    has been found to arise, for instance,
    when a juror is employed by a party or is closely related to a party or
    witness.” 
    Id. A jury
    consisting of even one biased juror is constitutionally
    infirm. 
    Id. at 237
    n.7.
    We decline to find implied bias on the facts here. The ostensible
    threat to the jury attested by one juror is hearsay-upon-hearsay. That fact
    in tandem with the fact that other jurors generally testified to threats of
    riots rather than of violence against the jury, leads us to doubt the
    reliability of the attestation. See State v. Evans, 
    169 N.W.2d 200
    , 205
    (Iowa 1969) (“Multiple hearsay is, of course, even more vulnerable to all
    the objections which attach to simple hearsay.”).
    Similarly, we do not find that the other threats of violence which
    reached the jury give rise to implied bias. As noted, these threats were
    vague, not directed at any juror, and only briefly discussed by the jurors
    in the jury’s deliberation.
    Finally on the facts here, we disagree with Christensen’s contention
    that the heightened community awareness surrounding this case, and
    jurors’ general knowledge thereof, gives rise to implied bias. It is certainly
    possible that a juror’s connection to the circumstances of a case or the
    community response can give rise to implied bias. See, e.g., Leonard v.
    United States, 
    378 U.S. 544
    , 544–45, 
    84 S. Ct. 1696
    , 1696 (1964) (per
    64
    curiam) (finding implied bias where jurors in a second case against
    Leonard were selected from a group which heard a guilty verdict in the
    first case). But here, various members of the community were on either
    sides of the guilt question, and through the voir dire process, potential
    jurors were stricken for cause after expressing opinions both favorable and
    unfavorable to Christensen. Christensen points to no facts concerning
    any of the jurors’ connection to the community response besides their
    membership in the community. Without an indication that a juror had
    such a close connection to the circumstances of the case or the community
    response that the juror would be unable to render a fair verdict, we cannot
    make a finding that any juror or the jury was tainted by implied bias. See
    
    Webster, 865 N.W.2d at 236
    .       Perhaps given the verdict, Christensen
    regrets not having moved for a change of venue, but he cannot remedy the
    consequences of that choice through an attack on the jury that has been
    selected after a thorough pretrial voir dire process.
    V. Conclusion.
    For the above reasons, the district court judgment is affirmed and
    the court of appeals decision is vacated.
    DECISION OF COURT OF APPEALS VACATED; DISTRICT COURT
    JUDGMENT AFFIRMED.
    All justices concur except Waterman, Mansfield, and Christensen,
    JJ., who concur specially, and McDonald, J., who takes no part.
    65
    #17–0085, State v. Christensen
    WATERMAN, Justice (concurring specially).
    I concur in the court’s opinion except for its discussion of the
    standard of review for the denial of a motion for new trial based on juror
    bias or misconduct. I write separately to emphasize that today’s decision
    refraining from deciding the standard of review in this appeal does not
    overrule our precedent or change the governing law, nor is a change
    warranted from our review for abuse of discretion.
    Indeed, in affirming the district court’s ruling that extraneous
    influences on the jury did not warrant a new trial, the majority applies
    the proper test from State v. Cullen, 
    357 N.W.2d 24
    , 27 (Iowa 1984),
    abrogated on other grounds by Ryan v. Arneson, 
    422 N.W.2d 491
    , 495
    (Iowa 1988). Citing Cullen, the majority reaches the right result, stating,
    “Based on our review of the record, we conclude that Christensen failed
    to show a reasonable probability that the verdict of the jury would have
    been different if the extraneous influence did not reach the jury in this
    case.”     But the majority fails to acknowledge the standard of review
    applied in Cullen, which emphasized the “[t]rial court has a broad
    discretion in ruling on these matters.        ‘We do not find an abuse of
    discretion . . . unless the action of the trial court is clearly unreasonable
    under the attendant circumstances.’ ”          
    Id. at 27
    (quoting State v.
    Harrington, 
    349 N.W.2d 758
    , 761 (Iowa 1984), abrogated on other
    grounds by 
    Ryan, 422 N.W.2d at 495
    ).
    In Doe v. Johnston, we declined an invitation to change this standard
    and explained the reasons for our deference to the trial court when
    extraneous material reaches the jury. 
    476 N.W.2d 28
    , 35 (Iowa 1991).
    Plaintiffs urge us to retreat from this standard and
    adopt, instead, a rule whereby prejudice is presumed to result
    from the introduction of extraneous material. We decline the
    66
    invitation to do so. A certain amount of leeway must be built
    into the system so that a relatively minor incident of
    misconduct is not allowed to disrupt what may have been a
    lengthy, costly, and otherwise fair trial. We are still convinced
    that the trial court is in the best position to objectively assess
    the impact of juror misconduct.
    Applying this objective standard to the present case, we
    find the court was well within its discretion in denying
    plaintiffs’ motion for new trial.
    
    Id. This reasoning
    is even more compelling today because the proliferation
    of social media increases the chances for juror exposure to extraneous
    material.
    The majority fails to provide a persuasive reason to change the
    standard of review now. We have long held that rulings on motions for
    new trial or mistrial based on juror misconduct or bias are reviewed for an
    abuse of discretion. See, e.g., State v. Gathercole, 
    877 N.W.2d 421
    , 427
    (Iowa 2016) (“We review the district court’s refusal to grant a mistrial [for
    juror bias] for an abuse of discretion.”); Fry v. Blauvelt, 
    818 N.W.2d 123
    ,
    128 (Iowa 2012) (“If the motion [for a new trial] is based on a discretionary
    ground such as misconduct it is reviewed for an abuse of discretion.”
    (alteration in original) (quoting Loehr v. Mettille, 
    806 N.W.2d 270
    , 277 (Iowa
    2011))); State v. Smith, 
    573 N.W.2d 14
    , 17 (Iowa 1997) (“We apply an abuse
    of discretion standard when reviewing the district court’s rulings on juror
    misconduct claims . . . .”); State v. Johnson, 
    445 N.W.2d 337
    , 340–41 (Iowa
    1989) (noting trial court’s “broad discretion in ruling on” motions for new
    trial based on juror bias or misconduct), overruled on other grounds by
    State v. Hill, 
    878 N.W.2d 269
    , 275 (Iowa 2016); State v. Hendrickson, 
    444 N.W.2d 468
    , 472 (Iowa 1989) (holding district “court did not abuse its
    discretion in denying defendant’s motions” challenging allegedly biased
    juror); State v. Powell, 
    400 N.W.2d 562
    , 565 (Iowa 1987) (“A trial court has
    broad discretion in matters involving alleged jury misconduct, and an
    67
    abuse of that discretion will not be found unless the action of the trial
    court is clearly unreasonable under the circumstances.”); State v.
    Christianson, 
    337 N.W.2d 502
    , 504 (Iowa 1983) (“Trial courts possess
    ‘broad discretion’ in deciding whether evidence of alleged jury misconduct
    warrants a new trial.” (quoting State v. Cuevas, 
    288 N.W.2d 525
    , 535 (Iowa
    1980)); Harris v. Deere & Co., 
    263 N.W.2d 727
    , 729 (Iowa 1978) (“Trial
    courts have broad discretion in ruling on motions predicated on jury
    misconduct.”), superseded on other grounds by rule, Iowa R. Evid. 606(b),
    as recognized in 
    Ryan, 422 N.W.2d at 495
    ; State v. Houston, 
    209 N.W.2d 42
    , 44–45 (Iowa 1973) (noting the “[t]rial court has broad discretion in
    determining whether evidence of claimed jury misconduct justifies a new
    trial” and its ruling “will not be set aside on appeal except upon showing
    an abuse of such discretion”). This law is well settled and should stay that
    way.
    But seeds of confusion were planted when we addressed the
    standard of review in State v. Webster, 
    865 N.W.2d 223
    , 231 (Iowa 2015).
    Under the heading “Standard of Review,” we accurately stated Iowa law
    as follows: “We review a denial of a motion for a new trial based upon juror
    misconduct or juror bias for an abuse of discretion.” 
    Id. Yet we
    muddied
    the waters in a footnote, stating,
    There is a question of the proper standard of review regarding
    fact-finding performed by the district court in the context of a
    motion for a new trial. There is authority in other jurisdictions
    that fact-finding made by the district court in considering a
    motion for a new trial is subject to review under a clearly
    erroneous standard.
    
    Id. at 231
    n.4. This footnote cited a single case for that proposition, State
    v. Dellinger, 
    696 S.E.2d 38
    , 42 (W. Va. 2010) (per curiam). The Dellinger
    68
    court described its standard of review as “deferential” to the trial court. 
    Id. at 42.
    In reviewing challenges to findings and rulings made by a
    circuit court, we apply a two-pronged deferential standard of
    review. We review the rulings of the circuit court concerning
    a new trial and its conclusion as to the existence of reversible
    error under an abuse of discretion standard, and we review
    the circuit court’s underlying factual findings under a clearly
    erroneous standard. Questions of law are subject to a de novo
    review.
    
    Id. (quoting State
    v. Vance, 
    535 S.E.2d 484
    , 487 (W. Va. 2000)). Thus, the
    trial court’s factual findings would be affirmed unless clearly erroneous—
    a far cry from appellate de novo review.
    Dellinger thus offers no support for de novo review of fact-finding for
    juror bias or misconduct. The Webster footnote, however, went on to cite
    a search and seizure case for the unremarkable proposition that we apply
    de novo review to fact-finding on constitutional 
    claims. 865 N.W.2d at 231
    n.4. By suggesting a connection between two separate lines of authority,
    the footnote purported to create an issue where none existed, concluding,
    “In this case, we do not resolve the issue because we generally agree with
    the fact-finding of the district court.” 
    Id. What issue?
    We should not
    compare apples and oranges. De novo review of constitutional issues has
    long coexisted with our deferential review of judgment calls trial courts
    make on a wide variety of rulings.          There arguably is a constitutional
    dimension to any ruling during a criminal trial, but that does not mean we
    should now start reviewing all trial rulings de novo. I would not start here.
    After Webster, we revisited the issue of juror bias claims arising from
    inaccurate midtrial publicity in Gathercole and squarely held our review is
    for an abuse of 
    discretion. 877 N.W.2d at 427
    . In Gathercole, while an
    attempted murder trial was ongoing, a local newspaper inaccurately
    69
    reported in an online article that the police had recovered the defendant’s
    palm print at the crime scene. 
    Id. at 425.
    The defendant moved for a
    mistrial or, alternatively, to poll the jury to determine if jurors saw the
    article. 
    Id. The district
    court denied the motions, and the defendant was
    convicted and appealed. 
    Id. at 426.
    We concluded the district court did
    not abuse its discretion in denying the motions for mistrial and jury
    polling. 
    Id. at 432–33.
    Despite our well-settled law on the standard of review, Christensen’s
    counsel took the hint buried in the Webster footnote and argues for
    de novo review. Our court today takes the same approach as in Webster,
    stopping short of deciding “the issue” over the standard of review because
    of general agreement with the district court’s factual findings. Yet the
    court adds a lengthy discussion likely to cause further confusion,
    unnecessary detours, and wasted court time.        The bottom line is that
    neither Webster nor today’s decision overrules our precedent holding
    abuse of discretion is the proper standard of review for juror-bias and
    misconduct cases.
    The majority also overlooks our long-standing precedent that the
    district court’s factual findings on juror bias or misconduct are binding on
    the appellate court when the findings are supported by substantial
    evidence. See Hutchinson v. Fort Des Moines Cmty. Servs., Inc., 
    252 Iowa 536
    , 543, 
    107 N.W.2d 567
    , 571 (1961) (“Where the facts on which a claim
    of misconduct is based are in dispute we will not interfere with the trial
    court’s determination of the matter if supported by substantial evidence.
    Such determination has about the same force as a jury verdict.” (quoting
    Hackaday v. Brackelsburg, 
    248 Iowa 1346
    , 1352, 
    85 N.W.2d 514
    , 517–18
    (1957))); see also Iowa R. App. P. 6.904(3)(a) (“Findings of fact in a law
    action . . . are binding upon the appellate court if supported by substantial
    70
    evidence.”); State v. Gomez Garcia, 
    904 N.W.2d 172
    , 177 (Iowa 2017)
    (“ ‘[A]buse of discretion occurs when a district court exercises its discretion
    on grounds or for reasons clearly untenable or to an extent clearly
    unreasonable.’ ‘A ground or reason is untenable when it is not supported
    by substantial evidence or when it is based on an erroneous application of
    the law.’ ” (alteration in original) (first quoting State v. Wilson, 
    878 N.W.2d 203
    , 210–11 (Iowa 2016); then quoting Graber v. City of Ankeny, 
    616 N.W.2d 633
    , 638 (Iowa 2000))). No one claims the district court’s factual
    findings in this case were not supported by substantial evidence.
    Neither Christensen nor today’s majority opinion cite a single case
    from any jurisdiction applying de novo review to fact-finding on juror bias
    or misconduct. We should not create an issue when none exists. Going
    forward, the standard of review for such cases should remain what it has
    been for generations—abuse of discretion.
    We have long adhered to the abuse-of-discretion standard because
    of the trial judge’s superior vantage point. The trial judge presides over
    the trial, with a front row seat for the testimony. See Mays v. C. Mac
    Chambers Co., 
    490 N.W.2d 800
    , 803 (Iowa 1992) (“The trial court has
    before it the whole scene, the action and incidents of the trial as they
    occur, and is in a much better position to judge whether the defendant
    has been prejudiced by misconduct of opposing counsel, if there is
    such. . . . The trial court occupies a position of vantage and is rightly given
    a considerable discretion in determining whether prejudice has resulted.”
    (alteration in original) (quoting Baysinger v. Haney, 
    261 Iowa 577
    , 582,
    
    155 N.W.2d 496
    , 499 (1968))). When jurors are questioned, the trial judge
    observes their demeanor firsthand. The trial judge is far better positioned
    than an appellate court reading a cold transcript to decide whether what
    71
    a juror said, did, or heard improperly influenced the verdict. The trial
    judge can read the room in real time.
    The United States Court of Appeals for the Fourth Circuit recently
    reiterated the rationale for this deferential review: “As the trial judge is in
    the best position to make this determination [regarding juror bias], the
    inquiry is committed to his discretion, including ample leeway to formulate
    the questions to be asked.” United States v. Smith, 
    919 F.3d 825
    , 834 (4th
    Cir. 2019). De novo review cedes too much control to an appellate court
    ill-suited to wield it. The Fourth Circuit aptly determined, “Th[e] trial judge
    made reasoned judgments [to detect juror bias]. And we are not here to
    micro-manage those considered choices.” 
    Id. The same
    is true here.
    For these reasons, I am unable to join the majority’s discussion of
    the standard of review. I otherwise concur in the opinion.
    Mansfield and Christensen, JJ., join this special concurrence.
