    I. Introduction
    This case concerns challenges by David Matusiewicz
    and Amy Gonzalez (together, the “defendants”) to their
    convictions for conspiracy to commit interstate stalking and
    cyberstalking, interstate stalking resulting in death, and cyber
    stalking resulting in death, and to their resulting life sentences
    for conspiracy to commit interstate stalking and cyberstalking
    which resulted in the death of Christine Belford, the ex-wife of
    David Matusiewicz. The defendants are siblings and were
    4
    indicted, along with their mother, Lenore Matusiewicz, after
    their father, Thomas Matusiewicz, shot and killed Belford and
    himself in the lobby of the New Castle County Courthouse.
    They engaged in a years-long conspiracy with Thomas
    Matusiewicz, an unindicted co-conspirator, to harass Belford,
    which ultimately resulted in her death. On appeal, each
    defendant challenges, inter alia, the constitutionality of the
    statutes under which they were convicted, the jury’s verdict on
    sufficiency of the evidence grounds, various evidentiary
    rulings of the District Court, as well as numerous challenges to
    their sentences of life imprisonment. Faced with numerous
    issues of first impression in this complicated case, District
    Judge Gerald McHugh, sitting by designation, handled this
    case with exceptional precision and care. We will affirm the
    District Court in all respects.
    II. Facts and Procedural History
    David Matusiewicz1 and Christine Belford were
    married from 2001 to 2006, during which time they had three
    children, L.M.1, L.M.2, and K.M.1 (the “children”). The
    couple and their children also lived with Belford’s one child
    from a previous marriage, K.M.2.2 After their divorce, Belford
    and David engaged in a bitter custody dispute, during which
    David accused Belford of being an unfit mother and suffering
    from mental health disorders. On February 13, 2007,
    following an evaluation by a psychologist who determined that
    1
    Hereinafter, we will refer to David Matusiewicz,
    Lenore Matusiewicz, and Thomas Matusiewicz, respectively,
    as David, Lenore, and Thomas.
    2
    To protect their privacy, we will use only initials to
    refer to the children.
    5
    David’s allegations were unfounded, the Delaware Family
    Court awarded joint custody of the children.
    On August 26, 2007, rather than let the children return
    from staying with David to live with Belford, David, along
    with his mother Lenore, kidnapped L.M.1, L.M.2, and K.M.1
    and absconded to Central America. During the kidnapping,
    David told L.M.1 that Belford had committed suicide. In
    March 2009, the children were located in Nicaragua and
    rescued, and David and Lenore were arrested. The children
    returned to live with Belford, who had been awarded sole
    custody during the kidnapping. David pleaded guilty to federal
    kidnapping charges and was sentenced to 48 months of
    imprisonment on December 10, 2009. Appendix (“App.”) 137.
    Later that month, while incarcerated, David sent a letter
    to his sister, Amy Gonzalez, in which he stated, “I’m done
    playing Mr. Nice Guy,” and urged her to “begin making
    complaints anonymously and repeatedly to [Delaware Youth
    and Family Services].” App. 3389-90, 7222. He also
    instructed her to “make sure Melinda’s website is up and has a
    true story on it and is well publicized.” App. 3390, 7222.
    Beginning in December 2009, a webpage was published that
    identified Belford and her children by name and set forth
    detailed claims against Belford of sexual abuse, physical
    abuse, and neglect of the children. That website was registered
    to Melinda Kula, the sister-in-law of Thomas and Lenore. It
    stated that the “[a]ctual names were used by the request and
    with the permission of David Matusiewicz.” App. 7882.
    In March and April 2011, Gonzalez published three
    YouTube videos, which included secret recordings of Belford
    and the children taken by a private investigator; posts claiming
    6
    Belford sexually abused her daughter, L.M.1; and images of
    polygraph test results of Lenore and Gonzalez, which
    described the accusations of sexual abuse. From May 2011
    through September 2012, David and Gonzalez had contact with
    David’s former girlfriend, Cindy Bender, and enlisted her to
    probe Belford for details about her life and to share what she
    learned, which included information from Belford’s private
    Facebook account.
    Acting on instructions received from David while he
    was in prison, Lenore and Gonzalez mailed letters that accused
    Belford of sexual abuse to numerous media outlets, to the
    children’s school and teachers, and to Belford’s family
    members, neighbors, employer, church, and other members of
    her community. The defendants also mailed letters and cards
    directly to Belford and her children. Gonzalez and Thomas
    solicited their friends to drive past Belford’s home and report
    on what they observed. The defendants also convinced a real
    estate agent in Delaware to conduct surveillance of Belford’s
    house and to provide them with information about Belford’s
    residence and about various persons who were part of
    Belford’s life and who were coming and going from her home.
    Between November 2010 and July 2011, the Delaware
    Family Court conducted a hearing over seven separate days on
    Belford’s petition for termination of David’s parental rights as
    to the children. On August 18, 2011, the Delaware Family
    Court entered an order terminating David’s parental rights as
    well as Thomas’s, Lenore’s, and Gonzalez’s familial rights
    (the “TPR Order”). App. 7827-68, 4310. The Delaware
    Supreme Court affirmed that decision. App. 2154-55. In spite
    of the TPR Order, the defendants continued to send letters to
    Belford’s home and made extrajudicial contact with the
    7
    lawyers, judges, and witnesses involved in the TPR matter.
    Thomas and Lenore made numerous phone calls to the
    chambers of the judge overseeing a separate civil matter
    between Belford and the Matusiewicz family, during which
    they told the judge’s assistant, referring to Belford, that the
    “bitch is going to get what is coming to her.” App. 3057.
    On December 1, 2011, Thomas and Lenore travelled to
    Delaware and showed up uninvited at Belford’s house.
    Although Belford was not at home, the children and Belford’s
    boyfriend were. Belford’s boyfriend instructed Thomas to
    leave. This trip was ostensibly to visit the children, despite the
    fact that Delaware Family Court had previously denied
    petitions by both Thomas and Gonzalez to visit the children.
    The night before the trip, Thomas and Gonzalez exchanged
    emails in which Thomas informed Gonzalez of the visit,
    instructed her to clean out his home safe, and told her that he
    would let her know how things worked out. App. 3319-21,
    8886. In response, Gonzalez gave Thomas her temporary cell
    phone number and told him to be careful. App. 8886. In the
    emails, Thomas and David refer to Belford by a
    nickname,“wb,” which stood for “Whore Bitch.” App. 3243-
    44. Thomas sent a letter to David after his visit that contained
    the details of what he had observed. App. 7226-28. After this
    visit, Belford took steps to sell her home and move. The
    defendants then obtained the real estate listing — before it was
    made publicly available — from the real estate agent whom
    they had enlisted to surveil Belford.
    On November 1, 2012, David sent Gonzalez an email
    saying, “[p]repare yourself to be managing four by this time in
    2013.” App. 3460-61. Gonzalez responded to the email by
    stating that she was “praying for it.” App. 3462. The
    8
    Government’s case agent later testified that the reference to
    “four” equated to David’s three children plus Gonzalez’s one
    child. App. 3461.
    On November 5, 2012, David filed a petition to reduce
    his back payments of child support in Delaware Family Court.
    A hearing was scheduled in Delaware, and although David was
    informed he could participate by phone as he resided with his
    family in Texas at the time, he chose to attend in person. David
    received permission from his probation officers to attend, but
    he failed to disclose to them that he could participate by phone
    or that his parents would be accompanying him. On February
    4, 2013, David, Lenore, and Thomas drove to Delaware in two
    vehicles, which were loaded with an assault rifle, handguns,
    military-style knives, thousands of rounds of ammunition,
    restraints, body armor, binoculars, an electric shock device, gas
    cans, a shovel, photographs of Belford’s children and
    residence, and handwritten notes about Belford’s neighbors.
    Thomas left a note for Gonzalez in a hutch in the family’s
    residence, instructing her to keep his guns for protection and
    that stated “hopefully we can end this BS now – up to Dave.”
    App. 3318, 7461.
    On February 11, 2013, Thomas and David entered the
    New Castle County Courthouse lobby, in Delaware, and
    remained there for approximately 25 to 30 minutes, during
    which time David and Thomas exchanged envelopes, before
    David passed through the security checkpoint. Belford entered
    the courthouse with her friend Laura “Beth” Mulford a short
    time later. Thomas then shot and killed both women, injured
    two police officers in an exchange of fire, and then shot himself
    in the head. Investigators recovered from Thomas’s person
    two death certificates that were filled out with the names of
    9
    Belford and her family court attorney. Investigators also found
    papers containing Thomas’s burial request during a search of
    David’s person following his arrest.
    On February 13, 2013 — two days later — Gonzalez
    submitted a petition for custody of the children to the Delaware
    Family Court in the New Castle County Courthouse, with a
    check dated February 12, 2013. App. 4306-07. The petition
    was denied. In the ensuing six months, Gonzalez continued to
    file additional custody petitions. App. 4307-12, 7974-8009.
    Gonzales also made repeated attempts to contact the children
    through the mail. App. 4312-13, 8542-45.
    On August 6, 2013, David Matusiewicz, Lenore
    Matusiewicz, and Amy Gonzalez were indicted on the
    following counts: (1) conspiracy to commit interstate stalking
    and cyberstalking, in violation of 18 U.S.C. §§ 2261A(1) and
    (2), all in violation of 18 U.S.C. § 371; (2) interstate stalking
    in violation of 18 U.S.C. §§ 2261A(1), 2261(b) and 2;
    (3) interstate stalking resulting in the death of Belford, in violation
    of 18 U.S.C. §§ 2261A(1), 2261(b) and 2; and (4) cyberstalking
    resulting in the death of Belford, in violation of 18 U.S.C.
    §§ 2261A(2), 2261(b) and 2. Counts One and Four were
    against all defendants. Count Two was only against Lenore.
    Count Three was against David and Lenore. Thomas was
    listed as an unindicted co-conspirator in the indictment. All
    three defendants pleaded not guilty, and the case proceeded to
    trial.
    We set forth a brief summary of the evidence introduced
    by the Government at trial relevant to the issues on appeal.
    This includes evidence that after the shooting, law enforcement
    officers found firearms and ammunition in the vehicles that the
    10
    Matusiewicz family had driven from Texas. The key to this
    vehicle was found on David’s person. The Government also
    introduced evidence of a surveillance video from a Walmart
    parking lot in Maryland that depicted Thomas, David, and
    Lenore walking around the vehicle with its trunk open,
    demonstrating that all three knew of the weapons and
    ammunition.
    Law enforcement recovered a red notebook entitled
    “Important Information for David Matusiewicz” from the
    vehicle that David and Thomas drove to the courthouse; the
    contents of this notebook were in Thomas’s handwriting. App.
    3224-35. Within were the real estate listing for and pictures of
    Belford’s home, accompanied by handwritten notes
    identifying the bedrooms in which Belford and her children
    slept. It also contained personal, identifying information on
    Belford’s family, lawyers, doctors, boyfriend, and employer,
    as well as a daily surveillance log tracking Belford’s
    movements over a twelve-day period in March 2010.
    Additionally, there was a page marked “HL,” which the
    Government argued stood for “hit list,” that identified sixteen
    individuals, including the judges, lawyers, and witnesses
    involved in the prior federal kidnapping and family court cases.
    App. 3249-53, 5442, 6995.
    The Government introduced evidence recovered from a
    search of Gonzalez’s residence. This included large volumes
    of correspondence with third parties about the stalking
    campaign. It also introduced letters from Thomas to Gonzalez
    that they “must drink to WB’s, [a nickname for Belford,] final
    day,” that Belford “can not keep” the children “at all costs,”
    and that Belford “can not [and] will not have our girls into her
    old age. Ain’t gonna happen.” App. 3442-43.
    11
    At trial, a key part of the Government’s case was that
    the defendants’ accusations that Belford sexually molested her
    children and suffered from mental health disorders were false
    and defamatory. The spreading of these false claims was an
    important part of the defendants’ campaign to harass and
    intimidate Belford. The Government provided ample evidence
    demonstrating the falsity of these claims. Notably, L.M.1
    testified that her mother did not abuse her, and refuted the
    specific claimed incidents of abuse advanced by the
    defendants. L.M.1 also testified that she was afraid when she
    learned of the allegations and saw her name and personal
    information online. The Government also provided the
    testimony of L.M.1’s pediatrician and psychologist who
    corroborated that L.M.1 never reported nor showed any signs
    of abuse.
    The Government also discredited the defendants’
    accusations of abuse by pointing out that the timeline of their
    claims of abuse did not add up. No accusations of sexual abuse
    were made prior to the kidnapping in August 2007. Evidence
    was introduced that at his TPR hearing, David testified that he
    kidnapped the children upon learning about the abuse in either
    July or August 2007. However, evidence also showed that
    David began preparing for the kidnapping as early as fall 2006.
    The Government introduced evidence that defendants gave
    contradictory and shifting statements about when and how they
    learned of the abuse, and about the details of the incidents of
    abuse. The Director of the Delaware Division of Family
    Services (“DDFS”), the state organization responsible for
    investigation of child abuse, also testified, explaining that
    DDFS did not open an investigation into the abuse because it
    12
    found that the defendants’ contradictory claims lacked
    credibility.
    Belford’s eldest child, K.M.2, testified that she, her
    mother, and her siblings were aware of the defendants’ conduct
    and it caused them to fear for their lives. L.M.1 also testified
    about her fear, and the pain of losing her mother. The
    Government also produced evidence from numerous third
    parties to whom Belford had confided her own fears of the
    defendants, resulting from their conduct. For example,
    Belford’s therapist testified as to the emotional and
    psychological toll that the defendants’ actions were having on
    Belford.
    After a five week trial, the jury convicted the defendants
    on all counts. On February 18, 2016, the District Court held a
    sentencing hearing. The District Court applied a number of
    sentencing enhancements, including: (1) the first-degree
    murder cross-reference pursuant to United States Sentencing
    Guidelines (“U.S.S.G.”) § 2A1.1; (2) the vulnerable victim
    enhancement pursuant to U.S.S.G. § 3A1.1(b)(1); and (3) the
    official victim enhancement pursuant to U.S.S.G.
    § 3A1.2(c)(1). App. 6057-6126. The District Court sentenced
    each of the defendants to a term of five years of imprisonment
    on Count One, and a term of life imprisonment for Count Four.
    App. 2-8, 10-15.3 This timely appeal followed.
    3
    Lenore died before the conclusion of her appeal, so her
    sentence was abated.
    13
    III. Analysis4
    The defendants raise numerous challenges to their
    convictions and sentences. David brings challenges to: (1) the
    sufficiency of the evidence; (2) the lack of a specific unanimity
    instruction; (3) the District Court’s “death resulted”
    instruction; (4) the District Court’s alleged judicial factfinding
    in violation of Apprendi v. New Jersey, 
    530 U.S. 466
    (2000),
    in imposing the sentence; (5) the application of the vulnerable
    victim and official victim sentencing enhancements; (6) the
    admission of the TPR Order into evidence; (7) the admission
    of Belford’s past therapy sessions and emails into evidence;
    and (8) the testimony of the FBI case agent vouching for the
    weight of the case. In addition to joining these challenges,
    Gonzalez also raises the following additional issues: (9) that
    the anti-cyberstalking statute violates the First Amendment and
    is void for vagueness; (10) that the District Court lacked
    jurisdiction to sit in the District of Delaware because venue was
    transferred out of Delaware; (11) that her polygraph evidence
    offered in rebuttal was erroneously excluded; (12) that the
    District Court erred in ruling that Government would be
    permitted to cross-examine any character witnesses about her
    prior conduct in relation to the kidnapping; and (13) that her
    sentence of life imprisonment violates the Eighth Amendment.
    We will address each of these issues in turn.
    A. Sufficiency of the Evidence Challenge
    4
    The District Court had jurisdiction over the underlying
    criminal proceedings pursuant to 18 U.S.C. § 3231. We have
    jurisdiction over these direct appeals pursuant to 28 U.S.C.
    § 1291 and 18 U.S.C. § 3742(a).
    14
    “We apply a ‘particularly deferential’ standard of
    review to a challenge to the sufficiency of evidence supporting
    a jury verdict.” United States v. Peppers, 
    302 F.3d 120
    , 125
    (3d Cir. 2002) (quoting United States v. Cothran, 
    286 F.3d 173
    ,
    175 (3d Cir. 2002)). Under this standard, we will affirm the
    verdict if “‘any rational juror’ could have found the challenged
    elements beyond a reasonable doubt, viewing the evidence in
    the manner that is most favorable to the government, neither
    reweighing evidence, nor making an independent
    determination as to witnesses’ credibility.” 
    Id. (quoting Cothran,
    286 F.3d at 175).
    Count One charged the defendants with conspiring to
    commit interstate stalking and cyberstalking, in violation of 18
    U.S.C. § 371. To establish a conspiracy under this section, the
    Government must prove: (1) an agreement between two or
    more persons to commit the substantive offense; (2) that each
    defendant knowingly joined the conspiracy; and (3) an overt
    act committed by one of the conspirators in furtherance of the
    conspiracy. See United States v. Gebbie, 
    294 F.3d 540
    , 544
    (3d Cir. 2002). This requires proof that a defendant has
    “knowledge of the conspiracy’s specific objective.” United
    States v. Caraballo-Rodriguez, 
    726 F.2d 418
    , 431 (3d Cir.
    2013) (en banc). We have held that “a conspiratorial
    agreement can be proven circumstantially based upon
    reasonable inferences drawn from actions and statements of the
    conspirators or from the circumstances surrounding the
    scheme.” United States v. McKee, 
    506 F.3d 225
    , 238 (3d Cir.
    2007).
    15
    Count Three charged only David and Lenore with
    interstate stalking, in violation of 18 U.S.C. § 2261A(1).5 To
    prove interstate stalking, the Government was required to
    prove that David:
    [(1)] travel[ed] in interstate or foreign commerce
    . . . [(2)] with the intent to kill, injure, harass,
    intimidate, or place under surveillance with
    intent to kill, injure, harass, or intimidate another
    person, and [(3)] in the course of, or as a result
    of, such travel . . . engage[d] in conduct that--
    (A) place[d] that person in reasonable fear
    of the death of, or serious bodily injury
    to—
    (i) that person;
    (ii) an immediate family member .
    . . of that person; or
    (iii) a spouse or intimate partner of
    that person; or
    (B) cause[d], attempt[ed] to cause, or
    would be reasonably expected to cause
    substantial emotional distress [to that
    person or their spouse, intimate partner,
    or immediate family member].
    18 U.S.C. § 2261A(1).
    Count Four, brought against all of the defendants, charged
    cyberstalking resulting in the death of Belford, in violation of 18
    U.S.C. §§ 2261A(2), 2261(b), and 2. We have held that to prove
    5
    Because Count Two was brought only against Lenore,
    it is not at issue in this appeal.
    16
    stalking under 18 U.S.C. § 2261A(2), the Government must
    establish that (1) the defendants used a facility of interstate
    commerce; (2) to engage in a course of conduct that places a
    person in reasonable fear of death or serious bodily injury, or
    causes substantial emotional distress, either to that person or to
    a partner or immediate family member; (3) “with the intent to
    kill, injure, harass, intimidate, or place under surveillance with
    intent to kill, injure, harass, or intimidate that person.” 18
    U.S.C. § 2261A(2); see also United States v. Fullmer, 
    584 F.3d 132
    , 163 (3d Cir. 2009). The statute defines a “course of
    conduct” as “a pattern of conduct composed of 2 or more acts,
    evidencing a continuity of purpose.” 18 U.S.C. § 2266. A
    defendant who violates § 2261A is eligible for a sentence of
    life imprisonment if the “death of the victim results.” 
    Id. § 2261(b)(1).
    The defendants each argue that the evidence presented
    to the jury was insufficient to convict them of any of the counts
    in the indictment. Their sufficiency challenges revolve around
    the same argument that was presented to and rejected by the
    jury: that Thomas acted alone in killing Belford and the
    defendants neither knew about nor participated in his plan.6
    The defendants argue that there is insufficient evidence of a
    conspiracy because there was no evidence of an express
    agreement to stalk or kill Belford. They do not dispute the
    existence of their campaign to spread accusations that Belford
    sexually abused the children, but contend that it was not a
    stalking campaign because it was meant to spur an
    investigation of these claims, which the defendants purport to
    have sincerely believed. However, the jury was presented with
    6
    The defendants do not contest the interstate commerce
    elements of any of the counts.
    17
    overwhelming evidence demonstrating both that the sexual
    abuse accusations against Belford were false and that
    defendants knew that these allegations were false.
    We have reviewed the substantial amount of evidence
    before the jury. Taken in the light most favorable to the
    Government, see 
    Peppers, 302 F.3d at 125
    , the evidence is
    more than sufficient to support the jury’s verdict in its entirety.
    Throughout the course of the five-week trial, the Government
    produced approximately 65 witnesses and over 760 exhibits,
    which show that the defendants conspired to engage in an
    escalating campaign of harassment, intimidation, and
    surveillance against Belford, all with the goal of regaining
    custody of the children. This three-year stalking campaign
    culminated in the murder of Belford in the New Castle County
    Courthouse lobby by Thomas, a member of the conspiracy.
    Both David and Gonzalez were intimately involved in
    this stalking campaign and conspiracy.            The evidence
    demonstrating David’s involvement included: directing his
    family to send letters to Belford’s acquaintances accusing
    Belford of sexual abuse; setting up the in-person court hearing
    that brought Belford to the courthouse where Thomas shot her;
    lying to probation officers about the need to attend the hearing
    in person; and traveling from Texas to Delaware in two vehicles
    that were filled with numerous weapons.
    The evidence demonstrating Gonzalez’s involvement
    included: spreading the false accusations of child abuse by
    creating online postings and YouTube videos, and sending
    defamatory emails and letters to Belford’s acquaintances;
    preparing false polygraph reports about these accusations;
    recruiting third parties to surveil and report on Belford and the
    18
    children; providing Thomas with her temporary cell phone
    number and cleaning out his safe when he traveled to Delaware
    in 2011 and showed up at Belford’s house; and filing numerous
    petitions for custody of the children beginning two days after
    Belford was killed. Thus, we conclude that the evidence was
    more than sufficient to support the conspiracy charges against
    David and Gonzalez.
    As to the charged violation of § 2261A(2), the
    Government produced sufficient evidence that David and
    Gonzalez committed cyberstalking that resulted in Belford’s
    death. Our review of the record demonstrates that the evidence
    shows that each of the defendants engaged in many more than
    the two requisite acts in furtherance of their long campaign to
    defame and accuse Belford of sexual abuse of her children.
    The purpose of this campaign, and the acts committed in
    furtherance thereof, was to regain custody of the children by
    removing Belford — or causing her to remove herself — from
    the equation. The evidence discussed above was more than
    sufficient for the jury to determine that the accusations against
    Belford were false, and thus infer that the defendants continued
    making these accusations with the intent to harass or intimidate
    Belford.
    The record also contains overwhelming evidence of the
    fear and emotional distress suffered by Belford and her
    children. This includes testimony by Belford’s children about
    their awareness and fear of the defendants’ conduct. The
    Government also produced evidence from numerous third
    parties to whom Belford had confided her fears of the
    defendants due to their conduct, including Belford’s
    19
    discussions with her therapist about the emotional and
    psychological toll that the defendants’ actions had on her.7
    Finally, the Government produced sufficient evidence
    to prove that the defendants’ conduct resulted in Belford’s
    death, thus making them eligible for life sentences under
    § 2261(b)(1). As discussed more thoroughly below with
    regard to the jury instruction challenge, the District Court
    properly instructed the jury that the defendants could be
    responsible for Belford’s death either because their actions
    were the actual and proximate cause of her death, or by way of
    co-conspirator liability, if she was killed by a co-conspirator
    acting in furtherance of the conspiracy. Our review of the
    record demonstrates that there is sufficient evidence to
    establish either theory of liability.
    7
    We have reviewed the record and conclude that it also
    contains sufficient evidence to support the count brought only
    against David for interstate stalking under § 2261A(1). This
    includes the evidence that he initiated the court hearing in
    Delaware, to which he traveled from Texas, with his parents in
    two vehicles that were filled with numerous weapons.
    Together with the fact that he did not inform his probation
    officers that he could participate in the hearing by telephone to
    get permission to leave the state, this is sufficient to support an
    inference by the jury that he traveled in interstate commerce
    with “the intent to kill, injure, harass, intimidate, or place under
    surveillance with intent to kill, injure, harass, or intimidate”
    Belford. 18 U.S.C. § 2261A(1). The above-discussed
    evidence of emotional distress that satisfied the § 2261A(2)
    violation is also sufficient to satisfy the § 2261A(1) violation.
    20
    David’s involvement in the stalking campaign, as well
    as his actions in setting up the court hearing and bringing
    Thomas to the courthouse where he then shot Belford, are
    sufficient to support an interference that he was the “but for”
    cause of Belford’s death. And as discussed above, there is
    sufficient evidence to support the inference that he had the
    specific intent that Belford should die. See supra, note 7. As
    to Gonzalez, her involvement in the stalking campaign also
    demonstrates that she was a “but for” cause of Belford’s death.
    Gonzalez’s numerous communications with her family
    members indicate that it was reasonably foreseeable to her that
    Belford’s murder at her family’s hands might soon come to
    pass, and support an inference that she was the proximate cause
    of Belford’s death. This evidence includes the correspondence
    from Thomas to Gonzales that the two drink to Belford’s “final
    day” and the communication from David that Gonzalez should
    prepare herself to soon be managing four children. Further,
    Gonzalez was ready to — and did — petition for custody of the
    children almost immediately after Belford was killed.8
    8
    Even if this evidence of the defendants’ direct
    involvement in Belford’s death were not sufficient, the jury’s
    finding that their actions resulted in Belford’s death is proper
    under co-conspirator liability. The doctrine of co-conspirator
    liability “permits the government to prove the guilt of one
    defendant through the acts of another committed within the
    scope of and in furtherance of a conspiracy of which the
    defendant was a member, provided the acts are reasonably
    foreseeable as a necessary or natural consequence of the
    conspiracy.” United States v. Lopez, 
    271 F.3d 472
    , 480 (3d
    Cir. 2001). Because there was sufficient evidence supporting
    the conspiracy conviction, there was also sufficient evidence
    supporting finding David and Gonzalez responsible for
    21
    For the foregoing reasons, the evidence produced at trial
    was more than sufficient to support the jury’s verdict.
    B. Jury Instruction Challenges
    The defendants raise two challenges to the District
    Court’s jury instructions. They contend that the District Court
    (1) erred in not providing a specific unanimity instruction, and
    (2) erred in its construction of the “death results” instruction.
    Our “[r]eview of the legal standard enunciated in a jury
    instruction is plenary, but review of the wording of the
    instruction, i.e., the expression, is for abuse of discretion.”
    United States v. Yeaman, 
    194 F.3d 442
    , 452 (3d Cir. 1999)
    (citation omitted). Because the defendants failed to object to
    the unanimity instructions or raise the specific unanimity
    instruction issue before the District Court, we review that issue
    for plain error. See United States v. Poulson, 
    871 F.3d 261
    ,
    270 (3d Cir. 2017). Under plain error review, we require the
    defendants to show that there is: (1) an error; (2) that is “clear
    Belford’s death pursuant to co-conspirator liability. Thomas,
    who shot Belford, was a co-conspirator. As discussed above, the
    Government submitted sufficient evidence that the goal of the
    conspiracy was to obtain custody of the children by driving
    Belford out of the picture. Killing Belford would clearly be in
    furtherance of this goal. And the evidence before the jury,
    including the communications between Thomas and the other
    defendants, the detailed surveillance of Belford, and the amount
    of weapons brought with the Matusiewicz family to Delaware,
    in addition to the other evidence that has been discussed above,
    demonstrates that Thomas’s murder of Belford was reasonably
    foreseeable to both David and Gonzalez.               Thus, the
    requirements of co-conspirator liability are satisfied.
    22
    or obvious;” and (3) that “affected the appellants’ substantial
    rights.” United States v. Stinson, 
    734 F.3d 180
    , 184 (3d Cir.
    2013) (citations omitted). “If those three prongs are satisfied,
    we have ‘the discretion to remedy the error — discretion which
    ought to be exercised only if the error seriously affect[s] the
    fairness, integrity, or public reputation of judicial
    proceedings.’” 
    Id. (quoting Puckett
    v. United States, 
    556 U.S. 129
    , 135 (2009)).
    1. Lack of a Specific Unanimity Instruction
    The defendants argue that the District Court erred
    because it failed to give a specific unanimity instruction to
    inform the jury that it must unanimously agree on which
    specific acts the defendants committed.               To prove
    cyberstalking under 18 U.S.C. § 2261A(2), the Government
    must, inter alia, establish that the defendant engaged in a course
    of conduct that placed a person in reasonable fear of death or
    serious bodily injury, or causes substantial emotional distress,
    either to that person or to a partner or immediate family
    member, “with the intent to kill, injure, harass, intimidate, or
    place under surveillance with intent to kill, injure, harass, or
    intimidate” that person. 18 U.S.C. § 2261A(2); 
    Fullmer, 584 F.3d at 163
    . The defendants argue that the jury was required to
    be unanimous on which of the specific acts it found to be part
    of the defendants’ course of conduct.
    “It is well settled that a defendant in a federal criminal
    trial has a constitutional right to a unanimous verdict.”
    
    Yeaman, 194 F.3d at 453
    . We have acknowledged that “[t]his
    includes the right to have the jury instructed that in order to
    convict, it must reach unanimous agreement on each element
    of the offense charged.” 
    Id. This is
    known as the “general
    23
    unanimity instruction.” United States v. Beros, 
    833 F.2d 455
    ,
    460 (3d Cir. 1987). Typically, when an indictment alleges a
    number of different factual bases for the defendants’ criminal
    liability, the general unanimity instruction ensures that the jury
    unanimously agrees on the factual basis for a conviction. 
    Id. However, “this
    does not mean one has a right to insist on an
    instruction requiring unanimous agreement on the means by
    which each element is satisfied.” 
    Yeaman, 194 F.3d at 453
    . In
    the case where “a statute enumerates alternative routes for its
    violation, it may be less clear . . . whether these are mere means
    of committing a single offense (for which unanimity is not
    required) or whether these are independent elements of the
    crime (for which unanimity is required).” 
    Id. Here, the
    defendants contend that specific unanimity is
    required because the statute contains multiple alternative
    routes for its violations, which consist of distinct elements. In
    their briefing, the defendants identify two different portions of
    the statute which they argue consist of distinct elements
    requiring specific unanimity: (1) the two specific acts that
    must be proven to establish the course of conduct requirement,
    and (2) the mens rea requirement. The Government contends
    that these are no more than distinct means of committing
    cyberstalking, not elements. The defendants argue in the
    alternative that the uncertainty over whether these are elements
    or means creates the potential for jury confusion, which would
    also necessitate a more specific unanimity instruction. See
    
    Beros, 833 F.2d at 460
    (observing that the general unanimity
    instruction can be insufficient “where the complexity of the
    case, or other factors, creates the potential that the jury will be
    confused”). The defendants thus contend that under Beros, the
    District Court was required to provide a more specific
    unanimity instruction. We disagree.
    24
    In Beros, we described a scenario in which the general
    unanimity instruction is not sufficient, concluding that
    When it appears . . . that there is a genuine
    possibility of jury confusion or that a conviction
    may occur as the result of different jurors
    concluding that the defendant committed
    different acts, the general unanimity instruction
    does not suffice. To correct any potential
    confusion in such a case, the trial judge must
    augment the general instruction to ensure the
    jury understands its duty to unanimously agree to
    a particular set of facts.
    
    Id. at 461
    (alteration in original) (emphasis omitted) (quoting
    United States v. Echeverry, 
    698 F.2d 375
    (9th Cir.), modified, 
    719 F.2d 974
    , 975 (9th Cir. 1983) (en banc)).
    The indictment at issue in Beros advanced multiple
    different theories for how the defendant had violated the
    relevant statute. 
    Id. at 460.
    There, the Government charged
    the defendant under a disjunctively worded statute, alleging
    that the defendant violated that statute by engaging in three
    separate and different acts. 
    Id. We held
    that the district court
    abused its discretion in not specifically instructing the jury that it
    had to be unanimous as to at least one of the three acts
    committed. 
    Id. at 460-63.
    We determined that “[w]hen the
    government chooses to prosecute under an indictment
    advancing multiple theories, it must prove beyond a reasonable
    doubt at least one of the theories to the satisfaction of the entire
    jury.” 
    Id. at 462.
    We went on to specify that the Government
    “cannot rely on a composite theory of guilt, producing twelve
    25
    jurors who unanimously thought the defendant was guilty but
    who were not unanimous in their assessment of which act
    supported the verdict.” 
    Id. Since Beros,
    we have reiterated that “the need for a
    specific unanimity instruction is the exception to the ‘routine
    case’ in which a ‘general unanimity instruction will ensure that
    the jury is unanimous on the factual basis for a conviction, even
    where an indictment alleges numerous factual bases for
    criminal liability.’” United States v. Cusumano, 
    943 F.2d 305
    ,
    312 (3d Cir. 1991) (quoting 
    Beros, 833 F.2d at 460
    ). And, we
    have held that “[t]he Beros rule comes into play only when the
    circumstances are such that the jury is likely to be confused as
    to whether it is required to be unanimous on an essential
    element.” 
    Id. Thus, Beros
    applies where the Government
    advances different factual theories concerning the defendants’
    charged conduct, each of which could independently satisfy the
    elements of the crime. In such a situation, a specific unanimity
    instruction is needed to ensure that the jury agrees on which of
    a (or a set of) charged act(s) that the defendant committed
    constituted criminal behavior. For example, in Beros, the
    indictment alleged that defendant embezzled money from a
    pension fund of which he was a trustee. 
    Beros, 833 F.2d at 458
    . One count of the indictment
    alleged three separate transactions of [his]
    criminal conduct: (1) the use of a Joint Council
    credit card to pay air fare for himself and his
    wife; (2) occupying a hotel suite that cost
    $160.00 per day rather than a single or double
    room which would cost no more than $60.00 per
    day; and (3) remaining in Florida for a couple of
    26
    additional days for personal reasons after the
    conclusion of the conference.
    
    Id. at 461
    .
    We held that a specific unanimity instruction was
    needed to ensure that the jury did not return a guilty verdict
    where all jurors agreed that the defendant engaged in criminal
    conduct, but some jurors thought that only the first transaction
    constituted criminal conduct, and others thought that only the
    second or third transactions constituted criminal conduct. 
    Id. We reasoned
    that in such a scenario, “the jury would
    unanimously conclude that there was a mode or manner of
    violating the law, but there would be no unanimity as to the
    predicate act. Also, under such a scenario, any verdict would
    be defective because of the lack of real unanimity.” 
    Id. at 462.
    In contrast, we have held that a specific unanimity instruction
    is not needed, because the same potential for juror confusion
    does not exist, where “the government did not allege different
    sets of facts, and the only possible confusion arose from the
    disjunctive nature of the charge under the statute.” 
    Cusumano, 943 F.2d at 312
    . Applying Beros, we have since observed that
    “[w]e have never required that jurors be in complete agreement
    as to the collateral or underlying facts which relate to the
    manner in which the culpable conduct was undertaken.”
    United States v. Jackson, 
    879 F.2d 85
    , 88 (3d Cir. 1989).
    We hold that the District Court was not required to issue
    a specific unanimity instruction in this case. Neither the mens
    rea requirements of § 2261A(2) nor the individual acts which
    constituted the statute’s “course of conduct” requirement
    constitute distinct elements of the offense. As to the mens rea
    requirement, we have held that different mental states in a
    27
    statute constitute alternate means and not alternate elements.
    See United States v. Navarro, 
    145 F.3d 580
    , 586 (3d Cir. 1998).
    In Navarro, we determined that “it is neither clear nor obvious
    that the three alternative mental states defined in § 1956[, the
    anti-money-laundering statute,] could not properly be treated
    as separate means of committing a single offense.” 
    Id. at 592.
    This conclusion followed from the Supreme Court’s decision
    in Schad v. Arizona, 
    501 U.S. 624
    (1991), which held that a
    specific unanimity instruction was not needed for a prosecution
    under “an Arizona statute which defined first-degree murder as
    being either (a) willful, deliberate, or premeditated, or (b)
    committed in the course of certain felonies,” because those two
    alternatives were not separate elements but instead “alternative
    means of satisfying an element of an offense.” 
    Navarro, 145 F.3d at 586
    (citing 
    Schad, 501 U.S. at 628
    ).
    Here, the statute requires that the defendant act “with
    the intent to kill, injure, harass, intimidate, or place under
    surveillance with intent to kill, injure, harass, or intimidate.”
    18 U.S.C. § 2261A(2). Nothing in the text of the statute or any
    cases interpreting it indicates that it was intended to create
    separate offenses for stalking “with the intent to kill” as
    opposed to stalking “with the intent to . . . injure” or “with the
    intent to . . . harass.” Instead, the statute requires that the
    defendant engage in “a pattern of conduct composed of 2 or
    more acts, evidencing a continuity of purpose” that “places that
    person in reasonable fear of the death of or serious bodily
    injury” or causes that person “substantial emotional distress.”
    
    Id. §§ 2261A(2),
    2266. A defendant violates the statute if that
    conduct is engaged in with one of the aforementioned mentes
    reae. We have noted that “different means for committing an
    offense ‘must reflect notions of equivalent blameworthiness or
    culpability.’” 
    Yeaman, 194 F.3d at 454
    n.6 (quoting United
    28
    States v. Edmonds, 
    80 F.3d 810
    , 820 (3d Cir. 1996)). The
    offense here stresses the effect that the defendant’s conduct has
    on the victim. Thus, as long as that conduct was taken with an
    intent to cause the victim harm, the specific mental state does
    not make a difference to the defendant’s culpability. This is
    evidenced by the fact that the statute sets forth different tiers of
    punishment based not on the mental state of the defendant, but
    on the harm suffered by the victim. See 18 U.S.C. § 2261(b).
    The decisions of our sister Courts of Appeals
    interpreting § 2261A(2) support our view that the mens rea
    requirement constitutes alternate means as opposed to alternate
    elements of the offense. The Court of Appeals for the Fourth
    Circuit, for instance, has declined to parse the different mentes
    reae, and observed that “[i]t is an element of the crime that [the
    defendant] have intended harm to a particular victim.” United
    States v. Shrader, 
    675 F.3d 300
    , 311 (4th Cir. 2012). The Court
    of Appeals for the Ninth Circuit has also treated the mens rea
    requirement as a single element in conducting its analysis of
    the statute. See United States v. Osinger, 
    753 F.3d 939
    , 947
    (9th Cir. 2014).
    A specific unanimity instruction was also not needed as
    to the course of conduct requirement. The jury is not required
    to agree on which specific acts were part of the stalking
    campaign. The statute defines the required “course of
    conduct” as “a pattern of conduct composed of 2 or more acts,
    evidencing a continuity of purpose.” 18 U.S.C. § 2266(2). The
    defendants argue that because, to be convicted of
    cyberstalking, they must have committed two or more acts as
    part of the course of conduct, the jury needs to agree on the
    specifics of which acts were committed with the requisite
    criminal intent.
    29
    However, the two or more specific acts that constitute a
    course of conduct are not distinct elements of the offense. The
    crux of the course of conduct requirement is that the defendants
    have engaged in “a pattern of conduct,” which “evidenc[es] a
    continuity of purpose.” 
    Id. § 2266(2).
    This language is
    significant. The focus is not on the individual acts as separate,
    distinct events, but instead on the purpose and scope of the
    defendants’ pattern of stalking conduct as a whole. See United
    States v. Conlan, 
    786 F.3d 380
    , 386 (5th Cir. 2015) (“[T]he
    statute’s intent requirement ‘modifies the cumulative course of
    conduct as a whole,’” and avoids criminalizing otherwise
    innocent acts) (quoting 
    Shrader, 675 F.3d at 311-12
    )). Nothing
    in the statute requires that the individual acts be criminal
    violations on their own. The statute does not require that a
    defendant commit multiple criminal acts to engage in a course
    of conduct. Instead, it is the pattern of conduct formed by the
    individual acts, undertaken with a continuity of purpose, that
    constitutes the criminal violation. As the Court of Appeals for
    the Fourth Circuit observed,
    While the statute does not impose a requirement
    that the government prove that each act was
    intended in isolation to cause serious distress or
    fear of bodily injury to the victim, the
    government is required to show that the totality
    of the defendant’s conduct “evidenc[ed] a
    continuity of purpose” to achieve the criminal
    end.
    
    Shrader, 675 F.3d at 311
    . The court then concluded that “[t]his
    statutory scheme reflects a clear understanding on the part of
    Congress that while severe emotional distress can of course be
    30
    the result of discrete traumatic acts, the persistent efforts of a
    disturbed harasser over a period of time . . . can be equally or
    even more injurious.” 
    Id. at 311-12.
    As a result, “[t]he
    cumulative effect of a course of stalking conduct may be
    greater than the sum of its individual parts.” 
    Id. at 312.
    The
    court thus rejected the intent and unanimity position that the
    defendants take here, because it held “[t]o read in a
    requirement that each act have its own specific intent element
    would undo the law’s protection for victims whose anguish is
    the result of persistent or repetitive conduct on the part of a
    harasser.” 
    Id. For the
    foregoing reasons, the District Court’s failure to
    include a specific unanimity instructions was not an error, and
    the defendants are not entitled to relief under plain error
    review.
    2. “Death Results” Instruction
    The defendants next argue that the District Court erred
    in its construction of the special instruction it gave the jury to
    determine whether the defendants qualified for the “death of
    the victim results” sentencing enhancement. 18 U.S.C. §
    2261(b)(1). The proper construction of this instruction was an
    issue of first impression for the District Court and remains one
    for us. The defendants concede that this instruction should be
    reviewed for plain error. Matusiewicz Br. 66, 75.
    The District Court gave the following “death results”
    instruction as part of its “Special Interrogatory Regarding the
    Death of Christine Belford — Counts Three and Four” jury
    instruction:
    31
    A person’s death “results” from an
    offense only if that offense caused, or brought
    about, that death. In determining whether the
    particular offenses charged in Counts 3 or 4
    caused Christine Belford’s death, you must
    affirmatively answer two questions. First, would
    Christine Belford’s death have occurred as
    alleged in the Indictment in the absence of the
    particular offense? Stated differently, you
    should decide whether Ms. Belford would have
    died at the New Castle County Courthouse on
    February 11, 2013, but for the particular offense.
    Second, was Christine Belford’s death the result
    of the particular offense in a real and meaningful
    way? This includes your consideration of
    whether her death was a reasonably foreseeable
    result of the particular offense and whether her
    death could be expected to follow as a natural
    consequence of the particular offense.
    With regard to the special interrogatories
    for Counts Three and Four, if you found the
    Defendant guilty of conspiracy under Count One
    it is not necessary for you to find that a particular
    defendant’s personal actions resulted in the death
    of Christine Belford. A defendant may be held
    accountable for the death of Christine Belford
    based on the legal rule that each member of a
    specific conspiracy is responsible for acts
    committed by the other members, as long as
    those acts were committed to help further or
    achieve the objective of the specific conspiracy
    and were reasonably foreseeable to the defendant
    32
    as a necessary or natural consequence of the
    agreement. In other words, under certain
    circumstances the act of one conspirator may be
    treated as the act of all. This means that all the
    conspirators may be held accountable for acts
    committed by any one or more of them, even
    though they did not all personally participate in
    that act themselves.
    In order for you to answer “yes” to the
    jury interrogatories for Counts Three or Four
    based upon this legal rule, you must find that the
    Government proved beyond a reasonable doubt
    each of the following four (4) requirements with
    regard to the charge at issue:
    First:        That the defendant was a member
    of the conspiracy to commit the
    particular offense charged in
    Count One of the Indictment;
    Second:       That while the defendant was still
    a member of the conspiracy, one or
    more of the other members of the
    same conspiracy also committed
    the offense charged in Count Three
    or Count Four, by committing each
    of the elements of that offense as I
    explained those elements to you in
    these instructions, and his or her
    acts therein resulted in the death of
    Christine Belford according to the
    instructions I have just given you.
    33
    However, the other member of the
    conspiracy need not have been
    found guilty of (or even charged
    with) the offense in question, as
    long as you find that the
    Government proved beyond a
    reasonable doubt that the other
    member committed the offense.
    Third:       That the other member of the
    conspiracy      committed       this
    particular offense within the scope
    of the unlawful agreement and to
    help further or achieve the
    objectives     of   the     specific
    conspiracy; and
    Fourth:      That Ms. Belford’s death was
    reasonably foreseeable to or
    reasonably anticipated by the
    defendant as a necessary or natural
    consequence of the unlawful
    agreement.
    The Government does not have to prove
    that the defendant specifically agreed or knew
    that Ms. Belford’s death would result. However,
    the Government must prove that Ms. Belford’s
    death was reasonably foreseeable to the
    defendant, as a member of the conspiracy, and
    within the scope of the agreement as the
    defendant understood it.
    
    34 Ohio App. 5871-72
    .
    The defendants contend that the District Court erred by
    giving this instruction. They contend that the instruction
    should have required that the jury find that there was an
    agreement among the defendants to cause Belford’s death.9
    They also contend that under the instructions the District Court
    gave, the jury could not have found that the defendants caused
    Belford’s death. The Government argues that this instruction
    properly set forth the two possible ways that the jury could find
    that the defendants’ actions resulted in Belford’s death. These
    theories of liability are that: (1) Belford’s death resulted from
    the defendants’ personal actions if the defendants’ personal
    actions were the actual and proximate cause of Belford’s death,
    or (2) the defendants are responsible for Belford’s death under
    co-conspirator liability.
    The District Court included both theories in its jury
    instruction and clearly distinguished between them. With
    respect to the first theory, that the defendants’ personal actions
    were the actual and proximate cause of Belford’s death, the
    District Court observed that its instruction held the jury to a
    higher standard than it believed the law required. See App. 61.
    Under this theory, the instruction required that the jurors find
    that each defendant’s conduct was the actual cause of Belford’s
    death and, in the context of the proximate cause question, that
    the death was “the result of the particular offense in a real and
    meaningful way,” including whether it was “reasonably
    9
    While the defendants contend that the District Court’s
    instruction was erroneous, they do not articulate clearly a
    proposed alternative instruction. Instead, much of their
    argument retreads their sufficiency of the evidence challenge.
    35
    foreseeable” and “could be expected to follow as a natural
    consequence of the particular offense.” App. 5871. The
    District Court observed that it included this language “to
    increase the government’s burden by highlighting for the jury
    the need for there to exist a genuine nexus between the
    Defendants’ conduct and the victim’s death.” App. 61. It
    explained that it required this heightened burden as to
    proximate cause, beyond what would be typically required for
    a proximate cause finding in tort law, as a “necessary
    safeguard” for the defendants’ rights. App. 61.
    Because the issue of how to define for the jury the proof
    required to establish that the defendants’ conduct caused the
    victim’s death, thus triggering the “death results” enhancement
    under § 2261(b)(1), is one of first impression, the District
    Court issued a supplemental opinion explaining its reasoning
    for fashioning the jury instruction the way it did. See App. 56-
    61. The District Court explained that it looked to the cases
    defining “death results” language in other statutes, namely
    Burrage v. United States, 
    571 U.S. 204
    (2014) and Paroline v.
    United States, 
    572 U.S. 434
    (2014), to form the basis for its
    causation instruction to the jury. The District Court then
    explained why it viewed the proximate cause requirement as
    requiring a heightened standard of proof here compared to that
    required under general tort law.
    We hold that the District Court did not err in crafting
    the jury instruction for the “death results” enhancement. The
    District Court properly followed Burrage and Paroline. In
    Burrage, the Supreme Court held that a “death results”
    sentencing enhancement in the Controlled Substances Act “is
    an element that must be submitted to the jury and found beyond
    a reasonable doubt,” because it “increased the minimum and
    36
    maximum sentences to which [the defendant] was exposed.”
    
    Burrage, 571 U.S. at 210
    . The Court noted that such language
    meant that “a defendant generally may not be convicted unless
    his conduct is ‘both (1) the actual cause, and (2) the ‘legal’
    cause (often called the ‘proximate cause’) of the result.’” 
    Id. (quoting 1
    W. LaFave, Substantive Criminal Law § 6.4(a),
    464-66 (2d ed. 2003)). The Court continued on to discuss the
    “actual cause” standard, determining that it “requires proof
    ‘that the harm would not have occurred’ in the absence of—
    that is, but for—the defendant’s conduct.” 
    Id. at 211
    (quoting
    Univ. of Tex. Sw. Med. Ctr. v. Nassar, 
    570 U.S. 338
    , 347-48
    (2013)). The Court did not discuss the proximate cause
    requirement, because it held that the actual cause requirement
    had not been satisfied where there was “no evidence” that the
    conduct at issue “was an independently sufficient cause of . . .
    death.” 
    Id. at 190.
    The Court did address in detail the concept of proximate
    cause in Paroline. It observed that “a requirement of proximate
    cause is more restrictive than a requirement of factual cause
    alone,” and that “proximate cause forecloses liability in
    situations where the causal link between conduct and result is
    so attenuated that the so-called consequence is more akin to
    mere 
    fortuity.” 572 U.S. at 446
    , 448. The Court struggled to
    define proximate cause, noting that it “defies easy summary”
    and “is ‘a flexible concept.’” 
    Id. at 444
    (quoting Bridge v.
    Phoenix Bond & Indem. Co., 
    553 U.S. 639
    , 654 (2008)). It
    determined that “to say that one event was a proximate cause
    of another means that it was not just any cause, but one with a
    sufficient connection to the result.” 
    Id. The Court
    observed
    that the proximate cause analysis in criminal and tort law “is
    parallel in many instances.” 
    Id. In its
    discussion, the Court
    noted that proximate cause is typically explained “in terms of
    37
    foreseeability or the scope of the risk created by the predicate
    conduct.” 
    Id. at 445.
    We hold that the District Court did not erroneously
    configure the portion of the “death results” instruction as to the
    direct theory of liability. The “actual cause” part of the District
    Court’s instruction appropriately tracks the “but for” causation
    requirement of 
    Burrage. 571 U.S. at 211
    . And the District
    Court’s instruction on proximate cause required even a more
    stringent finding than that discussed by the Supreme Court in
    Paroline. Not only did the District Court require that the jury
    find Belford’s “death was a reasonably foreseeable result of the
    particular offense,” as is traditionally considered the proximate
    cause requirement, but also the District Court went further,
    requiring that the death result from the offense “in a real and
    meaningful way” and as a “natural consequence.” App. 5871.
    The defendants have pointed to no authority that such a
    standard is insufficient to satisfy the proximate cause
    requirement. Thus, if anything, the District Court’s instruction
    on proximate cause provided more protection for the
    defendants’ rights than necessary under Supreme Court
    precedent. Accordingly, it was certainly not plain error for the
    District Court to give this instruction.
    Additionally, the District Court also properly instructed
    the jury that they could find the defendants liable under an
    alternative, co-conspirator theory of liability. The District
    Court’s instruction on when conspirators can be held liable for
    the actions of their co-conspirators was not plain error as it
    followed this Court’s model jury instructions and precedent.
    See Third Circuit’s Model Criminal Jury Instruction § 7.03
    “Responsibility For Substantive Offenses Committed By Co-
    Conspirators (Pinkerton Liability).” We have held that “a
    38
    participant in a conspiracy is liable for the reasonably
    foreseeable acts of his coconspirators in furtherance of the
    conspiracy.” United States v. Cross, 
    308 F.3d 308
    , 311 n.4 (3d
    Cir. 2002) (citing Pinkerton v. United States, 
    328 U.S. 640
    , 647
    (1946)). This is known as the Pinkerton theory of liability.
    This doctrine “permits the government to prove the guilt of one
    defendant through the acts of another committed within the
    scope of and in furtherance of a conspiracy of which the
    defendant was a member, provided the acts are reasonably
    foreseeable as a necessary or natural consequence of the
    conspiracy.” United States v. Lopez, 
    271 F.3d 472
    , 480 (3d
    Cir. 2001). Accordingly, we hold that the District Court did
    not plainly err in following our precedent and model jury
    instructions when instructing the jury that it could rely on co-
    conspirator liability.
    C. Substantive Challenges to the Prosecution of the Case
    1. First Amendment
    Gonzalez argues that the indictment should have been
    dismissed because it violated the First Amendment. She brings
    an as-applied challenge to the cyberstalking statute. David
    joins Gonzalez’s First Amendment arguments, but does not
    provide any separate discussion for an as-applied challenge as
    to his conduct. We review constitutional claims de novo.
    Garcia v. Att’y Gen, 
    665 F.3d 496
    , 502 (3d Cir. 2011).
    Gonzalez argues that she cannot be convicted for
    violating § 2261A(2) because her conduct constituted protected
    speech under the First Amendment. She argues that her speech
    — which consisted of, inter alia, sending emails to her co-
    defendants, sending correspondence to Belford and her
    39
    children, contacting third parties, posting polygraph results and
    videos with accompanying commentary — was protected
    because she was expressing her sincerely held belief about
    Belford. She contends that her speech about Belford
    constituted an opinion, and as such receives complete
    protection under the First Amendment.10 The Government
    10
    Gonzalez also briefly includes a vagueness and
    overbreadth challenge to the statute as a whole, which she
    supports with virtually no analysis. These challenges fail. “In
    the First Amendment context . . . a law may be invalidated as
    overbroad if ‘a substantial number of its applications are
    unconstitutional, judged in relation to the statute’s plainly
    legitimate sweep.’” United States v. Stevens, 
    559 U.S. 460
    ,
    473 (2010) (quoting Wash. State Grange v. Wash. State
    Republican Party, 
    552 U.S. 442
    , 449 n.6 (2008)). The
    Supreme Court has counseled that an overbreadth challenge is
    unlikely to “succeed against a law or regulation that is not
    specifically addressed to speech or to conduct necessarily
    associated with speech (such as picketing or demonstrating).”
    Virginia v. Hicks, 
    539 U.S. 113
    , 124 (2003). Furthermore, a
    statute is unconstitutionally vague only if it either (1) “fails to
    provide people of ordinary intelligence a reasonable
    opportunity to understand what conduct it prohibits” or (2)
    “authorizes or even encourages arbitrary and discriminatory
    enforcement.” Hill v. Colorado, 
    530 U.S. 703
    , 732 (2000). To
    this end, we consider whether a statute’s prohibitions “are set
    out in terms that the ordinary person exercising ordinary
    common sense can sufficiently understand and comply with.”
    U.S. Civil Serv. Comm’n v. Nat’l Ass’n of Letter Carriers, 
    413 U.S. 548
    , 579 (1973).
    Section    2261A      is   neither      overbroad      nor
    unconstitutionally vague. It is not targeted at “speech or to
    40
    argues that this statute does not violate the First Amendment
    because it prohibits conduct, and any speech included in its
    breadth falls into an exception that does not warrant First
    Amendment protection.
    The First Amendment “permit[s] restrictions upon the
    content of speech in a few limited areas.” United States v.
    Stevens, 
    559 U.S. 460
    , 468 (2010) (quoting R.A.V. v. City of
    St. Paul, 
    505 U.S. 377
    , 382-83 (1992)). The Supreme Court
    has identified certain “well-defined and narrowly limited
    conduct necessarily associated with speech,” but with
    harassing and intimidating conduct that is unprotected by the First
    Amendment. Thus, because “a substantial number of the
    statute’s applications” are not unconstitutional, it is not
    overbroad. Wash. State 
    Grange, 552 U.S. at 449
    n.6. And, it
    is not unconstitutionally vague, as it uses readily
    understandable terms such as “harass” and “intimidate,” and
    requires that a defendant intend to cause victims serious harm
    and in fact cause a reasonable fear of death or serious bodily
    injury. Thus, an “ordinary person exercising ordinary common
    sense can sufficiently understand and comply with” the terms
    of this statute. U.S. Civil Serv. 
    Comm’n, 413 U.S. at 579
    .
    Every one of our sister Courts of Appeals to consider similar
    overbreadth and vagueness challenges to § 2261A has rejected
    them. See United States v. Conlan, 
    786 F.3d 380
    , 385-86 (5th
    Cir. 2015); United States v. Osinger, 
    753 F.3d 939
    , 944-45 (9th
    Cir. 2014); United States v. Sayer, 
    748 F.3d 425
    , 436 (1st Cir.
    2014); United States v. Petrovic, 
    701 F.3d 849
    , 854-56 (8th
    Cir. 2012); United States v. Shrader, 
    675 F.3d 300
    , 310 (4th Cir.
    2012); United States v. Bowker, 
    372 F.3d 365
    , 379-83 (6th Cir.
    2004). The defendants have provided no authority or analysis
    to the contrary.
    41
    classes of speech” that can be proscribed without implicating the
    First Amendment. 
    Id. at 468-69
    (quoting Chaplinsky v. New
    Hampshire, 
    315 U.S. 568
    , 571-72 (1942)). Relevant here,
    these classes of speech include (1) “defamation” and (2)
    “speech integral to criminal conduct.” 
    Id. at 468.
    As to the first class of speech, the Supreme Court has
    held that defamatory statements are not protected by the First
    Amendment, reasoning that “[r]esort to epithets or personal
    abuse is not in any proper sense communication of information
    or opinion safeguarded by the Constitution, and its punishment
    as a criminal act would raise no question under that instrument.”
    Beauharnais v. Illinois, 
    343 U.S. 250
    , 257 (1952) (quoting
    Cantwell v. Connecticut, 
    310 U.S. 296
    , 309 (1940)). And while
    statements of personal opinion are protected under the First
    Amendment, see Gertz v. Robert Welch, Inc., 
    418 U.S. 323
    ,
    339-40 (1974), “there is no constitutional value in false
    statements of fact,” 
    id. at 340.
    False statements of fact are not
    protected because “[n]either the intentional lie nor the careless
    error materially advances society’s interest in ‘uninhibited,
    robust, and wide-open’ debate on public issues.” 
    Id. (quoting N.Y.
    Times Co. v. Sullivan, 
    376 U.S. 254
    , 270 (1970)).
    As to the second class of speech, the Supreme Court has
    long maintained that speech integral to engaging in criminal
    conduct does not warrant First Amendment protection. See
    Giboney v. Empire Storage & Ice Co., 
    336 U.S. 490
    , 498 (1949).
    Thus, “[s]pecific criminal acts are not protected speech even if
    speech is the means for their commission.” Packingham v.
    North Carolina, 
    137 S. Ct. 1730
    , 1737 (2017). In Giboney, the
    Court held that enjoining otherwise lawful picketing activities
    did not violate the First Amendment where the sole purpose of
    that picketing was to force a company to enter an unlawful
    42
    agreement in violation of Missouri’s criminal antitrust 
    laws. 336 U.S. at 501-02
    . The Court reasoned that such a restraint
    was justified because the otherwise lawful expressive activity
    was done for “the sole immediate purpose of continuing a
    violation of law.” 
    Id. at 501.
    The Court “reject[ed] the
    contention” that “the constitutional freedom for speech and
    press extends its immunity to speech or writing used as an
    integral part of conduct in violation of a valid criminal statute.”
    
    Id. at 498.
    The Court reasoned that “[s]uch an expansive
    interpretation of the constitutional guaranties of speech and
    press would make it practically impossible ever to enforce laws
    against . . . agreements and conspiracies deemed injurious to
    society.” 
    Id. at 502.
    We hold that 18 U.S.C. § 2261A does not violate the
    First Amendment as applied to Gonzalez, because she did not
    engage in protected speech. Her conduct was both defamatory
    and speech integral to criminal conduct. The defendants
    published false information about Belford on the internet and
    to third parties. Gonzalez, acting along with the other members
    of her family as a member of the conspiracy, defamed Belford
    by falsely labeling her as a mentally unfit abuser who sexually
    molested her own children. In addition, the members of the
    conspiracy defamed the children by falsely labeling them as
    victims of their mother’s sexual abuse.                There is
    overwhelming, uncontradicted evidence that the accusations
    that Belford sexually molested and abused her children were
    false.11 Falsely accusing Belford of sexual assault is
    11
    This evidence includes: (1) the testimony of L.M.1,
    the child who was alleged to be abused, denying any abuse
    occurred; (2) medical testimony corroborating L.M.1’s denial
    of abuse; (3) materially inconsistent statements by the
    43
    unquestionably defamatory and not protected by the First
    Amendment. See 
    Beauharnais, 343 U.S. at 257
    (“[I]t is
    libelous falsely to charge another with being a rapist.”). That
    Gonzalez claims to have sincerely held this belief, in light of
    the overwhelming evidence to the contrary, does not transform
    such a statement of fact into an opinion. 
    Id. As “there
    is no
    constitutional value in false statements of fact,” Gonzalez’s
    speech on this ground does not warrant First Amendment
    protection. 
    Gertz, 418 U.S. at 340
    .
    Even if it were not defamatory, this speech is still
    unprotected as it falls squarely into the “speech integral to
    criminal conduct” exception. The defendants’ speech served
    no legitimate purpose other than to harass and intimidate
    Belford, conduct that is illegal under § 2261A. Thus, the
    speech was that which had a “sole immediate purpose of
    continuing a violation of law.” 
    Giboney, 366 U.S. at 501
    . As
    discussed above, the evidence produced at trial sufficiently
    demonstrated that the defendants’ conduct was part of a course
    of conduct targeted at Belford, intended to cause her distress
    and to obtain custody of her children. Thus, Gonzalez’s
    internet postings and letters sent to Belford, the children, and
    third parties were actions that were integral to the course of
    conduct and the illegal purpose of the criminal cyberstalking
    conspiracy. As such, this conduct is not protected by the First
    Amendment.
    defendants regarding their claims of abuse; (4) the fact that the
    no claims of abuse were made until well after the kidnapping
    charges were brought; (5) testimony from Belford’s mental
    health providers; and (6) the analysis and conclusions found in
    the order of the Delaware Family Court terminating David’s
    parental rights and his family’s familial rights.
    44
    Our decision is in accord with those of our sister Courts
    of Appeals that have had the opportunity to consider First
    Amendment challenges to § 2261A. See, e.g., United States v.
    Conlan, 
    786 F.3d 380
    , 386 (5th Cir. 2015); United States v.
    Osinger, 
    753 F.3d 939
    , 947 (9th Cir. 2014); United States v.
    Sayer, 
    748 F.3d 425
    , 434 (1st Cir. 2014); United States v.
    Petrovic, 
    701 F.3d 849
    , 856 (8th Cir. 2012); United States v.
    Bowker, 
    372 F.3d 365
    , 379 (6th Cir. 2004), judgment vacated
    on other grounds, 
    543 U.S. 1182
    (2005), reinstated in relevant
    part, 125 Fed. App’x 701 (6th Cir. 2005).
    In Petrovic, the Court of Appeals for the Eighth Circuit
    held that the defendant’s conduct, including making highly
    offensive online communications, “may be proscribed
    consistent with the First Amendment.” 
    Petrovic, 701 F.3d at 856
    . There, the defendant had created a website through which
    he disseminated sexually explicit images and false statements
    about his ex-wife. 
    Id. at 852.
    He also sent mailings to third
    parties who knew the victim, including her family and co-
    workers, which contained similar information. 
    Id. Based on
    these facts, the court concluded that these communications
    “were integral to this criminal conduct as they constituted the
    means of carrying out his extortionate threats.” 
    Id. at 855.
    The
    court reached its conclusion due to the fact that “[s]ection
    2261A(2)(A) is directed toward ‘course[s] of conduct,’ not
    speech, and the conduct it proscribes is not ‘necessarily
    associated with speech.’” 
    Id. at 856
    (citation omitted). This is
    “[b]ecause the statute requires both malicious intent on the part
    of the defendant and substantial harm to the victim.” 
    Id. In Sayer,
    the Court of Appeals for the First Circuit
    rejected a First Amendment challenge to a conviction under
    45
    § 
    2261A(2)(A). 748 F.3d at 435
    . There, the defendant
    “creat[ed] false online advertisements and accounts in [the
    victim’s] name [and] impersonat[ed the victim] on the internet
    . . . which deceptively enticed men to [the victim’s] home.” 
    Id. at 434.
    The court concluded that “[t]o the extent his course of
    conduct targeting [the victim] involved speech at all, his
    speech is not protected,” because “it served only to implement
    [his] criminal purpose.” 
    Id. The court
    went on to observe that
    by prohibiting “a course of conduct done with ‘intent to kill,
    injure, harass, or place under surveillance with intent to kill,
    injure, harass, or intimidate, or cause substantial emotional
    distress,’” the statute “clearly targets conduct performed with
    serious criminal intent, not just speech that happens to cause
    annoyance or insult.” 
    Id. at 435
    (quoting 18 U.S.C.
    § 2261A(2)).
    In Osinger, the Court of Appeals for the Ninth Circuit
    reached a similar conclusion. There, the defendant sent
    “threatening text messages” to the victim and “designed a false
    Facebook page and sent emails to [her] co-workers containing
    nude photographs of 
    [her].” 753 F.3d at 947
    . The court held
    that “[a]ny expressive aspects of [the defendant’s] speech were
    not protected under the First Amendment because they were
    ‘integral to criminal conduct’ in intentionally harassing,
    intimidating or causing substantial emotional distress to [the
    victim].” 
    Id. This was
    because the defendant was engaged in
    a course of conduct with the intent to harass or intimidate the
    victim. 
    Id. In Conlan,
    the Court of Appeals for the Fifth Circuit
    similarly concluded that Ҥ 2261A does not criminalize
    constitutionally protected free 
    expression.” 786 F.3d at 386
    .
    There, the defendant conducted a “year-long campaign of
    46
    escalating sexual innuendo, threats of physical violence, and
    unwanted contacts with [the victims’] family, friends, and
    colleagues, culminating in an interstate trip to his victims’
    house.” 
    Id. The court
    concluded that because “one must both
    intend to cause victims serious harm and in fact cause a
    reasonable fear of death or serious bodily injury” to violate the
    statute, it criminalized conduct and not free expression
    protected by the Constitution. 
    Id. Each of
    these decisions supports our holding today.
    Here, what makes the defendants’ conduct violative of §
    2261A(2) is not that they simply made statements expressing
    their beliefs about Belford, but that these statements were sent
    to Belford, the children, and third parties as part of an
    extensive, and successful, campaign to threaten, intimidate, and
    harass Belford. As our sister Courts of Appeals have concluded,
    it is the intent with which the defendants’ engaged in this
    conduct, and the effect this conduct had on the victims, that
    makes what the defendants did a criminal violation. See
    
    Conlan, 786 F.3d at 386
    ; 
    Osinger, 753 F.3d at 947
    ; 
    Sayer, 748 F.3d at 435
    ; 
    Petrovic, 701 F.3d at 856
    . Accordingly, we reject
    the defendants’ First Amendment challenge, and will affirm
    the District Court’s decision to decline to dismiss the case on
    First Amendment grounds. The defendants’ convictions do not
    violate the First Amendment.
    2. Venue in Delaware
    The defendants also argue that the District Court did not
    have “jurisdiction” to preside over the case. This argument is
    based on the defendants’ interpretation of an order from the
    district court judge first assigned to the case, Judge Gregory M.
    Sleet, which they claim transferred the case out of the district.
    47
    The defendants contend that because he then recused himself,
    Judge Sleet was not permitted to enter a later clarifying order
    specifying that he did not transfer the case in this earlier order.
    They also argue that under the law-of-the-case doctrine, Judge
    McHugh, who took over the case after all of the district judges
    in the District of Delaware were recused, was bound to transfer
    the case out of the district. We review a judge’s decision to
    reconsider his or her predecessor’s ruling for an abuse of
    discretion. Fagan v. City of Vineland, 
    22 F.3d 1283
    , 1290 (3d
    Cir. 1994).
    On September 12, 2014, Judge Sleet granted the
    defendants’ motions for recusal, and recused himself from the
    case. Gonzalez’s recusal motion was titled “Motion for
    Transfer and Recusal,” and it requested a transfer of venue in
    addition to Judge Sleet’s recusal. App. 16-23. The
    memorandum opinion accompanying Judge Sleet’s order did
    not mention venue transfer. See 
    id. The defendants
    argued
    that in addition to recusing himself, and all of the district judges
    in the District of Delaware, from the case, this order also
    transferred venue out of the District of Delaware. The
    Government disputed that characterization, and the parties then
    briefed the issue. On December 4, 2014, Judge Sleet issued an
    amended order that clarified that the Motion for Transfer and
    Recusal was granted in part, as to recusal only. App. 24.
    Nonetheless, the defendants filed motions to enforce Judge
    Sleet’s transfer of venue. On March 10, 2015, Judge McHugh
    issued an order, ruling on those motions to enforce, and finding
    that Judge Sleet never granted the venue-transfer portion of the
    motion to transfer. App. 25-29. The defendants argue that this
    was an abuse of discretion. We disagree.
    48
    Judge Sleet’s memorandum opinion clearly did not
    transfer venue, because venue transfer is not mentioned in the
    opinion. Because venue transfer was not discussed, Judge Sleet
    thus also did not identify to what judicial district venue the case
    was purportedly transferred or the reasons for that transfer.
    Without such explanations, venue could not properly be
    transferred. See In re United States, 
    273 F.3d 380
    , 387 (3d Cir.
    2001) (requiring the district court to provide “a statement of
    reasons for granting the motion to transfer so that the appellate
    court has a basis to determine whether the district court soundly
    exercised its discretion and considered the appropriate factors”
    that contains “a sufficient explanation of the factors
    considered, the weight accorded them, and the balancing
    performed”). That this order did not and was never intended to
    transfer venue is confirmed by the amended order, which
    clarified that the prior order granted the motion only as to
    recusal and not as to venue transfer. We have held that “[t]he
    law of the case doctrine does not preclude a trial judge from
    clarifying or correcting an earlier, ambiguous ruling.” 
    Fagan, 22 F.3d at 1290
    . That is what Judge Sleet did here. Thus,
    Judge McHugh did not abuse his discretion by failing to transfer
    venue, because Judge Sleet’s opinions make clear that venue was
    never transferred.
    D. Evidentiary Challenges
    We exercise plenary review over the District Court’s
    interpretation of the Federal Rules of Evidence. United States
    v. Duka, 
    671 F.3d 329
    , 348 (3d Cir. 2011). We review the
    District Court’s application of the Rules and its decisions to
    admit or exclude evidence for abuse of discretion. 
    Id. The District
    Court abuses its discretion if its analysis and
    conclusions are “arbitrary or irrational,” or if its “decision
    49
    ‘rests upon a clearly erroneous finding of fact, an errant
    conclusion of law or an improper application of law to fact.’”
    United States v. Schneider, 
    801 F.3d 186
    , 198 (3d Cir. 2015)
    (quoting Newton v. Merrill Lynch, Pierce, Fenner & Smith,
    Inc., 
    259 F.3d 154
    , 165-66 (3d Cir. 2001), and United States v.
    Universal Rehab. Servs. (PA), Inc., 
    205 F.3d 657
    , 665 (3d Cir.
    2000) (en banc)).
    1. Family Court Opinion
    The defendants argue that the District Court erred by
    admitting into evidence the August 18, 2011 TPR Order from
    the Delaware Family Court. See App. 7827-68 (Gov. Ex. 308).
    By way of the TPR Order, the Delaware Family Court
    terminated David’s parental rights, as well as the familial rights
    of his sister, Gonzalez, and their parents, with respect to
    David’s children. The defendants argue that the TPR Order
    should have been excluded pursuant to Federal Rule of
    Evidence 403 because any probative value that it provided was
    substantially outweighed by the risk of unfair prejudice. They
    contend that factual findings as well as the statements about
    David contained in the TPR Order could have prejudiced the
    jury, since these statements were made by a judge. Further,
    they assert that introducing the findings of a judge would
    prejudice the jury because they would be likely to defer to these
    findings and not reach an independent verdict. The defendants
    also argue that the TPR Order constituted improper character
    evidence because it painted David as a liar and manipulator and
    was evidence of his prior bad acts which should not have been
    admissible pursuant to Federal Rule of Evidence 404(b).
    The defendants filed a motion in limine to have the TPR
    Order excluded pursuant to Rules 403 and 404(b). The District
    50
    Court denied the motion, and admitted the TPR Order as
    relevant to the defendants’ “state of mind and motive in
    continuing to make allegations against” Belford and as to their
    motive for engaging in the stalking. App. 51. The court
    admitted the TPR Order with a cautionary instruction. App.
    51. It also further explained its ruling from the bench, after
    defense counsel again objected to the TPR Order being sent to
    the jury. App. 5753-54. The District Court made redactions to
    the TPR Order that were “carefully considered to remove from
    the jury’s consideration the evidence that would really be
    prejudicial.” App. 5753. The court also observed that the risk
    of prejudice was lessened by the fact that most of the witnesses
    who testified during the TPR hearing also testified at trial, and
    that the one who did not, Dr. Orlov, was available to be called
    by the defense, who chose not to do so.
    The District Court gave multiple cautionary
    instructions. The first was immediately after the TPR Order
    was admitted into evidence and discussed by the Government’s
    witness. See App. 2153-54. The court instructed that the TPR
    Order, which included the Family Court’s findings that
    David’s accusations of abuse by the children’s mother were
    false, “does not definitively conclude that no abuse took place
    because that issue is in front of the Court here.” App. 2153.
    The District Court went on to explain that “what you just heard
    about what the Family Court held might be considered as
    relevant to potentially a motive for future things that occurred
    including the stalking that the Government alleges occurred.”
    App. 2153-54. The court also explained that the findings “are
    not automatically binding on you” and should be considered in
    light of all the evidence that the jury hears. App. 2154.
    51
    The District Court provided a second cautionary
    instruction during the recitation of jury instructions. It
    cautioned the jury that
    [t]hese materials were allowed into evidence to
    provide you with background for the offenses
    charged here. You may consider the findings
    made in Family Court in determining the
    defendant’s state of mind, including knowledge,
    intent and motive with respect to the offenses
    charged in this indictment.
    You should not, however, conclude
    simply because the Family Court made certain
    factual findings that you are bound by those
    findings. As I’ve told you it is your duty to
    decide the fact from the evidence you’ve heard
    and seen in court during this trial. That is your
    job and yours only.
    App. 5655.
    Rule 403 provides that “[t]he court may exclude
    relevant evidence if its probative value is substantially
    outweighed by a danger of one or more of the following: unfair
    prejudice, confusing the issues, misleading the jury, undue delay,
    wasting time, or needlessly presenting cumulative evidence.”
    Rule 403 “creates a presumption of admissibility.” United
    States v. Claxton, 
    766 F.3d 280
    , 302 (3d Cir. 2014). In
    considering a challenge under Rule 403, “the trial court ‘must
    appraise the genuine need for the challenged evidence and
    balance that necessity against the risk of prejudice to the
    defendant.’” Gov’t of V.I. v. Archibald, 
    987 F.2d 180
    , 186 (3d
    52
    Cir. 1993) (internal quotations omitted) (quoting United States
    v. Blyden, 
    964 F.2d 1375
    , 1378 (3d Cir. 1992)).
    Typically, “we exercise great restraint in reviewing a
    district court’s ruling on the admissibility of evidence under
    Rule 403.” 
    Id. However, we
    do not defer to the district court
    where “the trial judge fails to perform the required balancing
    and to explain the grounds for denying a Rule 403 objection.”
    
    Id. Where, as
    here, a district court applies Rule 403 to
    “determine the admissibility of Rule 404(b) evidence,” the
    district court “must undertake some analysis, i.e., provide
    ‘meaningful balancing.’” United States v. Repak, 
    852 F.3d 230
    , 246 (3d Cir. 2017) (quoting United States v. Caldwell,
    
    760 F.3d 267
    , 283 (3d Cir. 2014)).
    The defendants contend that the admissibility of the
    TPR Order should be subject to plenary review, because the
    District Court did not sufficiently explain the reasoning of its
    Rule 403 ruling. We disagree. The District Court properly
    engaged in the requisite balancing and “articulate[d] . . . a
    rational explanation” for its ruling. United States v. Sampson,
    
    980 F.2d 883
    , 889 (3d Cir. 1992). The District Court in fact
    issued a written ruling on the admissibility of the TPR Order,
    which noted the relevance of the evidence and acknowledged
    that a cautionary instruction was needed to address the
    concerns raised by the defendants. See App. 51. Additionally,
    the District Court gave further reasons for its ruling from the
    bench. App. 5753-54. These explanations warrant deference
    as they far exceed the “bare recitation of Rule 403” that we
    have held is insufficient to warrant deference. See, e.g., 
    Repak, 852 F.3d at 246
    . The District Court explained why the TPR
    Order was relevant, observed that its prejudicial effect was
    mitigated by the redactions as well as the fact that the findings
    53
    in the TPR Order were based on the testimony of witnesses
    who either testified or were available to testify at trial, and only
    admitted the TPR order for a limited purpose under Rule
    404(b),12 with the appropriate limiting instructions.
    Accordingly, we will review the Rule 403 ruling for abuse of
    discretion.
    The District Court did not abuse its discretion in
    admitting the TPR Order. The TPR Order was highly relevant
    and was a key piece of evidence in the case as it was the
    Government’s argument that the TPR Order was one of the
    main motivating factors that spurred the killing of Belford.
    The Government argued that David was particularly angered
    by the specific language used in the TPR Order. The
    Government, in fact, introduced a version of the TPR Order
    annotated with the defendants’ handwritten notes as evidence
    of the effect that it had on them. See App. 7323. Further, this
    was used as evidence that the defendants believed the
    Delaware Family Court had let them down, and the Government
    argued that the detailed examination and rejection of the
    defendants’ claims that the children were abused contained in
    the TPR Order rebuts the defendants’ central defense in this
    case that they were not intending to harass Belford, but were
    instead just attempting to raise awareness for their claims of
    abuse and have them be heard. The District Court did not
    12
    Rule 404(b) permits otherwise inadmissible character
    evidence to be admitted if it is used not to show a person’s
    character, but instead for certain limited other purposes. See
    Fed. R. Evid. 404(b)(2) (“This evidence may be admissible for
    another purpose, such as proving motive, opportunity, intent,
    preparation, plan, knowledge, identity, absence of mistake, or
    lack of accident.”).
    54
    abuse its discretion in admitting the TPR Order as highly
    relevant to the Government’s case.
    The prejudicial effects about which the defendants
    complain were mitigated by the cautionary instructions that the
    District Court gave to the jury. “[W]e presume that the jury will
    follow a curative instruction unless there is an ‘overwhelming
    probability’ that the jury will be unable to follow it and a strong
    likelihood that the effect of the evidence would be ‘devastating’
    to the defendant.” United States v. Newby, 
    11 F.3d 1143
    , 1147
    (3d Cir. 1993) (internal quotation marks and citations omitted)
    (quoting Greer v. Miller, 
    483 U.S. 756
    , 766 n.8 (1987)). We
    have ruled that the provision of a limiting instruction can alleviate
    the potential prejudice of evidence admitted over a Rule 403
    objection. See, e.g., 
    Repak, 852 F.3d at 247
    (“[T]he District
    Court provided a limiting instruction, mitigating any concern
    that the jury would have used this evidence to draw a
    propensity inference.”); United States v. Sriyuth, 
    98 F.3d 739
    ,
    748 (3d Cir. 1996) (“[T]he risk of unfair prejudice was
    minimized by the district court’s instruction to the jury on the
    limited use of the sexual assault evidence.”). The District
    Court gave two thorough curative instructions, in addition to
    redacting the most prejudicial parts of the TPR Order. The jury
    was expressly instructed that it was not bound by anything said
    in TPR Order and that it was to use it in considering the
    defendants’ state of mind in committing the stalking offenses,
    and not for other impermissible purposes.13 The curative
    13
    Any potential prejudice from the TPR Order was
    further limited by the fact that, during closing arguments, the
    Government incorporated the cautionary instruction and
    qualified its arguments to explicitly note that the TPR Order
    was nonbinding. See App. 5442, 5593.
    55
    instructions here were sufficient to ameliorate the alleged
    unfair prejudice of which the defendants complain.
    Alternatively, the defendants argue that the TPR Order
    was unduly prejudicial because it was issued by a court and the
    jury would feel bound to follow the finding of a judge, even
    with the limiting instruction. They argue that we should follow
    the Court of Appeals for the Ninth Circuit’s opinion in United
    States v. Sine, in which that court observed “that factual
    testimony from a judge unduly can affect a jury” and that
    “jurors are likely to defer to findings and determinations
    relevant to credibility made by an authoritative, professional
    factfinder rather than determine those issues for themselves.”
    
    493 F.3d 1021
    , 1033 (9th Cir. 2007). However, Sine is
    distinguishable. There, the government chose to present the
    factual findings from a prior civil case in which the defendant
    was involved in lieu of other evidence to prove those same
    facts at trial, and sought to rely on the fact that these factual
    findings were found by a judge, as a method of reinforcing the
    truth of the findings. 
    Id. at 1035.
    The court held that it was
    improper for the government to attempt to usurp the jury’s role
    as a factfinder in this way, and that the admission of these
    findings in lieu of the direct evidence constituted inadmissible
    hearsay. 
    Id. at 1033,
    1036. As discussed above, none of these
    concerns are present here, where the Government did not
    attempt to present the TPR Order for the truth of the factual
    findings, presented the testimony of the witnesses from the
    TPR hearing in its case, and itself stressed the Court’s limiting
    instruction.
    In sum, in light of the limiting instruction and the
    redactions, we hold that the District Court did not abuse its
    discretion in admitting the TPR Order.
    56
    2. Belford’s Therapy Tapes and Emails
    The defendants next argue that the District Court abused
    its discretion in admitting Belford’s statements to her therapist
    as part of her therapy sessions as well as emails Belford sent to
    her neighbors and colleagues. The defendants argue that these
    statements are hearsay, and they were not properly admitted
    under any hearsay exception, such as Rules 803(3) and 803(4).
    The defendants also argue that the admission of this evidence
    violated their rights under the Confrontation Clause.
    The defendants objected at trial to the admission of this
    evidence. Therefore, they contend that the abuse of discretion
    standard should be applied. The Government argues that
    although this evidence was objected to, the defendants did not
    raise the same arguments as to its inadmissibility that they now
    raise, and thus we should review the admissibility of this
    evidence for plain error. We need not resolve this dispute,
    because even under the more deferential abuse of discretion
    standard, the District Court properly admitted this evidence.
    a. Therapy Sessions
    The defendants first object to the admission of portions
    of recordings taken of Belford’s sixteen therapy sessions to
    treat her anxiety and depression with Dawn Edgar, her
    therapist. Edgar testified at trial, and these recordings were
    admitted through her testimony as evidence of Belford’s state
    of mind. The Government contends that they are admissible
    under two separate hearsay exceptions: (1) as evidence of the
    declarant’s state of mind, and (2) as a statement made for
    purposes of medical diagnosis or treatment. Fed. R. Evid.
    57
    803(3) & (4). Rule 803(4) provides a hearsay exception for a
    “Statement Made for Medical Diagnosis or Treatment,” which
    is defined as follows: “A statement that: (A) is made for—and
    is reasonably pertinent to—medical diagnosis or treatment; and
    (B) describes medical history; past or present symptoms or
    sensations; their inception; or their general cause.” Fed. R.
    Evid. 803(4).
    The defendants argue that Belford’s statements to her
    therapist are not covered by Rule 803(4), because this
    exception should not apply to statements made to mental health
    professionals. They contend that statements made to mental
    health professionals do not exhibit the same indicia of reliability
    as do statements made to other medical professionals. The
    defendants claim that these statements are unreliable because
    the issue of the truth of a patient’s statements regarding his or
    her mental condition is not as relevant for mental health
    professionals as it is for physical health doctors. As a result,
    the defendants argue that the statements were not made for
    “medical diagnosis or treatment,” and thus do not qualify for
    the Rule 803(4) exception.
    We disagree. We have not previously decided whether
    Rule 803(4) covers statements made to a mental health
    professional, rather than to a physician. However, the plain
    text of the Rule does not limit its application to statements
    made to a physician. Rule 803(4) focuses on the purpose for
    which the statement is made, not on the identity of the
    recipient. The advisory committee note to Rule 803(4) makes
    clear that statements made to a broad category of individuals
    other than physicians are covered by the exception, such as
    those made to “hospital attendants, ambulance drivers, or even
    members of the family.” Fed. R. Evid. 803 advisory committee
    58
    note to paragraph (4). There is no indication from Rule 803(4)
    or its accompanying advisory committee notes that it should
    not extend to statements made to mental health professionals.
    The defendants have provided no persuasive authority in
    support of their position. If Rule 803(4) extends to cover
    statements made to non-medical persons such as family
    members, it logically also covers statements made to other
    medical professionals, including those who specialize in
    mental health. Accordingly, we hold that the exception in Rule
    803(4) applies to statements made to therapists and mental
    health professionals.
    The decisions of our sister Courts of Appeals support
    this conclusion, as every Court of Appeals to consider this
    issue has determined that statements made to a mental health
    professional for purposes of diagnosis or treatment qualify
    under the hearsay exception in Rule 803(4). See, e.g., United
    States v. Kappell, 
    418 F.3d 550
    , 556 (6th Cir. 2005);
    Danaipour v. McLarey, 
    386 F.3d 289
    , 297 (1st Cir. 2004);
    United States v. Yellow, 
    18 F.3d 1438
    , 1442 (8th Cir. 1994);
    Morgan v. Foretich, 
    846 F.2d 941
    , 949 n.17 (4th Cir. 1988);
    United States v. Lechoco, 
    542 F.2d 84
    , 89 n.6 (D.C. Cir. 1976),
    abrogated on other grounds by In re Sealed Case, 
    352 F.3d 409
    (D.C. Cir. 2003).
    Belford made the statements in question to her therapist,
    who she was consulting for treatment of her anxiety and
    depression. Thus, these statements were made for “medical
    diagnosis or treatment.” Fed. R. Evid. 803(4)(A). These
    statements concerned Belford’s emotional state, including
    discussions of her anxiety and depression, as well as their
    cause. These types of statements are plainly within the
    confines of Rule 803(4)(B) as they are a description of
    59
    Belford’s “past or present symptoms or sensations; their
    inception; or their general cause.” Fed. R. Evid. 803(4)(B).
    Accordingly, we hold that Belford’s statements to her therapist
    were admissible pursuant to Rule 803(4).14
    14
    In the alternative, the Government argues that these
    recordings are admissible pursuant to Rule 803(3), the state of
    mind exception. The District Court admitted them because it
    found that they qualified under Rule 803(3) to show Belford’s
    emotional state, which was a necessary element of the charges.
    Rule 803(3) provides that:
    A statement of the declarant’s then-existing state
    of mind (such as motive, intent, or plan) or
    emotional, sensory, or physical condition (such
    as mental feeling, pain, or bodily health), but not
    including a statement of memory or belief to
    prove the fact remembered or believed unless it
    relates to the validity or terms of the declarant’s
    will.
    Belford’s statements to her therapist consist of Belford’s
    description of her emotional condition. As the District Court
    correctly observed, the recorded nature of the statements was
    relevant to showing Belford’s state of mind because the tenor
    of her voice in the recordings provided strong evidence of her
    emotional condition at the time. These statements were
    admitted to show the effect that the defendants’ stalking
    campaign had on Belford and her resulting emotional state, not
    for the truth of what she was saying. Belford’s emotional
    condition and state of mind are directly relevant to the
    Government’s burden to prove that the defendants’ actions
    caused her substantial emotional distress. Accordingly, this
    60
    b. Emails
    The second set of hearsay challenges that the defendants
    bring are to emails that Belford sent to third parties. These
    emails concerned Belford’s emotional condition.              The
    defendants argue that these emails were inadmissible because
    they contained more than just a description of Belford’s
    emotional state, as they also contained explanations of the facts
    that were the cause of that emotional state. The defendants
    contend that under the Rule 803(3) hearsay state of mind
    exception, the hearsay statements cannot encompass the facts
    that create the relevant state of mind. The Government
    contends that these emails were not admitted to show the truth
    of the descriptions of the defendants’ acts contained therein,
    but to demonstrate that Belford was aware of the acts. The
    Government also identifies the other admissible evidence at
    trial that established these acts by the defendants. Thus, it
    contends, any descriptions of the acts in Belford’s emails
    would be harmless, because these acts were already before the
    jury. See Gov. Br. 120 n.66 (identifying the portions of the
    record where the acts described in the emails were also
    described by other witnesses).
    We hold that the District Court properly admitted these
    emails under the Rule 803(3) state of mind exception. The
    emails offer Belford’s descriptions of the defendants’ acts in the
    context of how those acts affected her emotional state, fitting
    squarely within the state of mind exception. These emails
    demonstrate that Belford was aware of defendants’ actions and
    that those actions were causing her emotional distress, which
    evidence squarely fits within Rule 803(3) and are also
    admissible under that rule.
    61
    are both substantive elements of the cyberstalking offense that
    the Government was required to prove. See 18 U.S.C.
    § 2261A(2).       Accordingly, these emails demonstrated
    Belford’s “state of mind” and “emotional . . . condition,” Fed.
    R. Evid. 803(3), and thus do not constitute hearsay. We hold
    that the District Court did not abuse its discretion in admitting
    this evidence under Rule 803(3).15
    c. Confrontation Clause
    The defendants also challenge the admission of all of
    Belford’s statements at trial under the Confrontation Clause of
    the Sixth Amendment. They contend that their rights were
    violated by the admission of this evidence, which they contend
    constitutes testimony by Belford, because they were unable to
    cross-examine Belford at trial.
    The Confrontation Clause of the Sixth Amendment
    provides that, “[i]n all criminal prosecutions, the accused shall
    15
    Additionally, these statements also qualify as non-
    hearsay under Rule 801(c) because the Government was not
    offering them for the truth of the matter asserted in those
    statements. See Fed. R. Evid. 801(c) advisory committee note
    (“If the significance of an offered statement lies solely in the
    fact that it was made, no issue is raised as to the truth of
    anything asserted, and the statement is not hearsay.”); see also
    United States v. Figueroa, 
    818 F.2d 1020
    , 1026 (1st Cir. 1987)
    (“Statements proffered to show something other than the
    accuracy of their contents—to show, say, the knowledge or
    state of mind of the declarant or one in conversation with
    him—are not considered hearsay.” (citing VI Wigmore on
    Evidence § 1789 at 235 (3d ed. 1940))).
    62
    enjoy the right . . . to be confronted with the witnesses against
    him.” U.S. Const. amend. VI. A “witness” is any individual who
    bears “testimony” against the defendant, and such “testimony”
    can be contained in any functional equivalent of a witness’s in-
    court statements, such as affidavits or “pretrial statements that
    declarants would reasonably expect to be used
    prosecutorially.” Crawford v. Washington, 
    541 U.S. 36
    , 51
    (2004). To fall within the ambit of the Confrontation Clause,
    proposed evidence must constitute a “statement,” and such a
    statement must contain testimonial hearsay, meaning that the
    statement was “a ‘solemn declaration or affirmation made for
    the purpose of establishing or proving some fact;’ and . . . was
    made primarily for the purpose of ‘prov[ing] past events
    potentially relevant to later criminal prosecution.’” United
    States v. Stimler, 
    864 F.3d 253
    , 272 (3d Cir. 2017) (alteration
    in original) (footnote omitted) (first quoting Melendez-Diaz v.
    Massachusetts, 
    557 U.S. 305
    , 310 (2009); then quoting
    Michigan v. Bryant, 
    562 U.S. 344
    , 361 (2011)). Examples of
    testimonial statements include “prior testimony” as well as
    “police interrogations.” 
    Crawford, 541 U.S. at 68
    .
    The defendants contend that Belford’s prior statements
    to her therapist as presented in the recordings were testimonial
    in nature. They argue that a therapy session “mimic[s]” the
    format of a law enforcement interview of a crime victim,
    because both scenarios are a “structured setting” that involves
    questioning. Gonzalez Br. 66. They also argue that the two
    are similar because both involve discussions of unlawful
    conduct.
    We disagree. Belford’s statements to her therapist are
    not testimonial in nature. As her therapist testified, the purpose
    of Belford’s visits were to receive therapy to treat her anxiety
    63
    and depression. The purpose of a visit to a therapist is not to
    create a record for a future criminal case. As we discussed
    previously, these statements were not hearsay because they
    were made for the purposes of “medical diagnosis or
    treatment.” Fed. R. Evid. 803(4)(A). Indeed, as the Supreme
    Court has observed, many of the hearsay exceptions, including
    Rule 803(4) “rest on the belief that certain statements are, by
    their nature, made for a purpose other than use in a prosecution
    and therefore should not be barred by hearsay prohibitions.”
    
    Bryant, 562 U.S. at 362
    n.9. It is clear from the record that the
    purpose of Belford’s visits to her therapist was not to create a
    record for a future prosecution that could be used as a substitute
    for trial testimony. Accordingly, the admission of Belford’s
    statements as evidence did not violate the Confrontation
    Clause.
    3. Testimony of FBI Case Agent
    Next, the defendants assert that the District Court erred
    by permitting the FBI case agent to vouch for the strength of
    the Government’s case. On redirect examination of the case
    agent, the District Court permitted him to respond to the single
    question: “in the course of your investigation into this matter,
    has anything occurred that has shaken your belief in your
    actions?” App. 3696. The case agent responded in the
    negative. 
    Id. The District
    Court permitted this redirect
    question, pursuant to the Government’s request, after counsel
    for co-defendant Lenore on cross-examination asked the case
    agent if he, “at any point in time,” had any “doubts” about the
    defendants’ involvement in Belford’s death. App. 3638.
    Counsel for the defendants David and Gonzalez did not object
    to this initial line of questioning by counsel for Lenore, but did
    object to the Government’s question on redirect. The District
    64
    Court overruled these objections, reasoning that counsel for
    Lenore had opened the door to this redirect question, and
    counsel for David and Gonzalez had implicitly consented to it
    by not objecting to this line of questioning at the time.
    Afterwards, the District Court then provided a limiting
    instruction, informing the jury that it had permitted the
    question in response to questions by defense counsel on cross-
    examination and directing the jury that they were to follow
    only their own assessment of the evidence.
    We review for abuse of discretion “the District Court’s
    ruling on a challenge to prosecutorial statements objected to at
    trial.” United States v. Vitillo, 
    490 F.3d 314
    , 325 (3d Cir.
    2007). And we review a “vouching issue for abuse of
    discretion and harmless error.” 
    Id. “Vouching constitutes
    an
    assurance by the prosecuting attorney of the credibility of a
    Government witness through personal knowledge or by other
    information outside of the testimony before the jury.” United
    States v. Walker, 
    155 F.3d 180
    , 184 (3d Cir. 1998) (citing
    United States v. Lawn, 
    355 U.S. 339
    , 359 n.15 (1958)). To
    prevail on a vouching claim, a defendant must demonstrate
    that: “(1) the prosecutor [assured] the jury that the testimony
    of a Government witness is credible; and (2) this assurance is
    based on either the prosecutor’s personal knowledge, or other
    information not contained in the record.” 
    Id. at 187.
    We have
    observed that a “defendant must be able to identify as the basis
    for that comment an explicit or implicit reference to either the
    personal knowledge of the prosecuting attorney or information
    not contained in the record.” 
    Id. Impermissible vouching
    can
    occur through the use of witness testimony. United States v.
    Berrios, 
    676 F.3d 118
    , 134 (3d Cir. 2012). However, “where
    the purported vouching is a ‘reasonable response to allegations
    of [impropriety]’ by the defense, it is not improper.” 
    Id. 65 (alteration
    in original) (quoting United States v. Weatherly, 
    525 F.3d 265
    , 272 (3d Cir. 2008)).
    Here, the challenged statement of the FBI case agent did
    not constitute vouching. As the District Court acknowledged
    both in overruling the defense objections and in providing the
    limiting instruction to the jury, the challenged question was
    permitted only as a response to the earlier questions on cross-
    examination about any doubts the case agent might have had
    about the strength of the case. The Government’s follow-up
    question was a “reasonable response” to these defense
    questions. Id.16 Accordingly, we hold that the District Court
    did not abuse its discretion by permitting this question.
    4. Exclusion of Polygraph Rebuttal Evidence
    The defendants next argue that the District Court
    committed reversible error by preventing Gonzalez from
    introducing the results of a polygraph examination as rebuttal
    evidence. They contend that this violated her right to an
    opportunity to present a meaningful defense under the Sixth
    and Fourteenth Amendments. They argue that the polygraph
    rebuttal evidence should not have been excluded because it was
    relevant, because the polygraph results are admissible under
    Daubert v. Merrell Dow Pharm., Inc., 
    509 U.S. 579
    (1993), and
    16
    Because we hold that this question was permissible as
    a “reasonable response” to the questions asked by defense
    counsel, we need not decide whether this question and
    response even constitutes vouching due to the fact that neither
    the prosecuting attorney nor the case agent gave a personal
    assurance about the credibility of any witness. See 
    Walker, 155 F.3d at 184
    .
    66
    because there is no per se rule excluding polygraph results in this
    Circuit. See United States v. Lee, 
    315 F.3d 206
    , 214 (3d Cir.
    2003). The defendants contend that this evidence was
    necessary to rebut the prosecution’s challenges to both
    Gonzalez’s veracity and the veracity of statements made in
    another polygraph examination, which was a key part of the
    defendants’ defamation campaign against Belford. Finally, they
    contend that the exclusion of this evidence unfairly prejudiced
    Gonzalez because it hindered her ability to rebut the
    Government’s assertions that certain statements she made as
    part of her harassment campaign were false and defamatory.
    The District Court provided a supplemental opinion in
    which it explained its decision to exclude this rebuttal
    polygraph evidence. See App. 62-73. The District Court
    explained that it could have excluded the evidence on
    procedural grounds because the defendants did not timely or
    properly disclose the experts or summaries of the expert reports
    of those persons who administered this polygraph examination,
    and previously had informed the Government that they would
    not be seeking to admit this evidence. However, the District
    Court instead chose to exclude this evidence on substantive
    grounds, because it did not find the polygraph results evidence
    to be reliable, but rather found that the defendants improperly
    sought to offer it as direct evidence of the defendants’ guilt or
    innocence. The District Court looked to recent scientific
    evidence on the reliability of polygraphs examinations, and
    determined that the scientific consensus reinforced doubts
    about their reliability.
    In considering the constitutionality of a rule that
    operated as a per se exclusion of polygraph evidence, the
    Supreme Court has held that “[a] defendant’s right to present
    67
    relevant evidence is not unlimited, but rather is subject to
    reasonable restrictions.” United States v. Scheffer, 
    523 U.S. 303
    , 308 (1998). The Court observed that “federal rulemakers
    have broad latitude under the Constitution to establish rules
    excluding evidence from criminal trials,” and that they had
    “found the exclusion of evidence to be unconstitutionally
    arbitrary or disproportionate only where it has infringed upon
    a weighty interest of the accused.” 
    Id. Applying these
    principles, the Court held that because of concerns over the
    reliability of polygraph evidence, a per se exclusion of any
    polygraph evidence did not violate the Constitution. 
    Id. at 311.
    It determined that a rule excluding polygraph evidence “does
    not implicate any significant interest of the accused” because
    in the absence of polygraph evidence, a defendant still
    maintains the ability to testify on their own behalf and present
    their own factual evidence. 
    Id. at 316-17.
    The Court
    concluded that the exclusion of polygraph evidence does not
    significantly impair a defendant’s defense, as polygraph
    evidence is merely “expert opinion testimony to bolster [the
    defendant’s] own credibility.” 
    Id. at 317.
    The District Court did not err by excluding Gonzalez’s
    polygraph evidence. Because a per se rule against polygraph
    evidence is constitutionally permissible, see 
    id. at 311,
    then the
    District Court’s decision to exclude this polygraph evidence
    after a thorough, well-reasoned, and careful opinion, is
    certainly not an abuse of discretion. For the reasons articulated
    in its supplemental opinion, the District Court’s concerns about
    the polygraph examination’s reliability were sufficient to
    support its decision to exclude the proffered polygraph rebuttal
    evidence. Accordingly, we will affirm the District Court’s
    exclusion of the polygraph evidence.
    68
    5. Character Evidence Cross-Examination
    The defendants next argue that the District Court erred
    in ruling that if Gonzalez called witnesses to testify to her
    character, the Government would be permitted to either cross-
    examine those witnesses on Gonzalez’s character or offer some
    evidence in rebuttal. Gonzalez sought to present the testimony
    of several character witnesses as to her honesty, peacefulness,
    and law-abiding behavior, but declined to do so after the
    District Court ruled that the Government would be permitted
    to provide rebuttal evidence about her involvement in the
    kidnapping of her nieces by David and Lenore. She contends
    that this denied her the opportunity to put on a complete
    defense.
    We disagree. Rule 404(a) directly addresses this
    situation. It states that “a defendant may offer evidence of the
    defendant’s pertinent trait, and if the evidence is admitted, the
    prosecutor may offer evidence to rebut it.” Fed. R. Evid.
    404(a)(2)(A). Rule 405 permits “an inquiry into relevant
    specific instances of the person’s conduct” during “cross-
    examination of the character witness.” Fed. R. Evid. 405(a).
    The District Court was well within the bounds of the Federal
    Rules of Evidence when it ruled that it would permit the
    Government to present rebuttal evidence if Gonzalez opened
    the door on the issue of her character. Accordingly, the District
    Court did not abuse its discretion in making this ruling.
    Further, by electing not to put on such evidence, Gonzalez
    failed to preserve this issue for appeal. See United States v.
    Moskovits, 
    86 F.3d 1303
    , 1305-06 (3d Cir. 1996).17
    17
    The defendants also contend that the cumulative
    effect of these evidentiary errors was prejudicial. This
    69
    E. Sentencing Challenges
    The defendants also raise four challenges to their
    sentences. They bring a challenge under the Fifth and Sixth
    Amendments to the District Court’s factual findings,
    challenges to the District Court’s application of the Official
    Victim and Vulnerable Victim Guidelines, and an Eighth
    Amendment challenge to the length of Gonzalez’s sentence.
    “We exercise plenary review over the District Court’s
    interpretation of the Sentencing Guidelines and constitutional
    questions.” United States v. Lennon, 
    372 F.3d 535
    , 538 (3d
    Cir. 2004). And, “[w]e review the District Court’s factual
    findings for clear error, and the District Court’s application of
    those facts to the Guidelines for an abuse of discretion.” 
    Id. (citations omitted).
    1. Fifth and Sixth Amendments
    The defendants contend that the District Court violated
    both the Fifth and Sixth Amendments in calculating their
    advisory Sentencing Guidelines ranges using a preponderance
    of the evidence standard to make additional findings of fact.
    They argue that the District Court should only have applied
    factual findings made beyond a reasonable doubt by the jury
    and should not have made any additional factual findings.
    They contend that the District Court’s actions violate the
    Supreme Court’s sentencing jurisprudence following
    cumulative error challenge was not raised below, and thus is
    subject to review for plain error. Because none of the rulings
    was an error, by definition, the cumulative effect of each non-
    error could not be prejudicial.
    70
    
    Apprendi, 530 U.S. at 490
    . We disagree. The District Court
    did not violate Apprendi because it did not make any findings
    that raised the defendants’ sentences above the statutory
    maximum. Instead the District Court’s findings adjusted the
    applicable range of the advisory Sentencing Guidelines.
    We have previously rejected the defendants’ position in
    an en banc decision, where we held that Apprendi does not
    apply when a district court makes factual findings that affect
    the advisory guidelines but not the statutory maximum. See
    United States v. Grier, 
    475 F.3d 556
    , 565 (3d Cir. 2007) (en
    banc). In Grier we confronted a similar challenge and held
    “that the right to proof beyond a reasonable doubt does not
    apply to facts relevant to enhancements under an advisory
    Guidelines regime.” 
    Id. Nevertheless, the
    defendants argue
    that we should not follow the binding precedent of Grier
    because intervening decisions by the Supreme Court, such as
    Alleyne v. United States, 
    570 U.S. 99
    (2013), have cast doubt
    on its reasoning. However, we have expressly rejected that
    position and continued to follow Grier. See United States v.
    Smith, 
    751 F.3d 107
    , 117 (3d Cir. 2014) (determining that
    Alleyne “did not curtail a sentencing court’s ability to find facts
    relevant in selecting a sentence within the prescribed statutory
    range”).
    Although the defendants encourage us to follow the
    dissenting opinion in Grier, we are bound to follow Grier and
    Smith. Here, the statutory maximum was life imprisonment.
    18 U.S.C. § 2261(b)(1). The District Court made additional
    factual findings to apply the First Degree Murder sentencing
    cross-reference, which “applies when death results from the
    commission of certain felonies.” U.S.S.G. § 2A1.1 cmt. n.1.
    This increased the defendants’ Guidelines range. But the
    71
    District Court’s findings did not increase the statutory
    maximum. Thus, the District Court did not run afoul of
    
    Apprendi. 530 U.S. at 490
    . In sum, the District Court did not
    violate the defendants’ Fifth and Sixth Amendment rights.18
    2. Official Victim Enhancement
    The defendants19 next contend that the District Court
    erred in applying the Official Victim enhancement in the
    Sentencing Guidelines, U.S.S.G. § 3A1.2(c)(1), to David. The
    Official Victim enhancement, in relevant part, applies
    18
    We decline to consider the additional challenge to his
    Guideline range that David seeks to incorporate by reference
    to his arguments made before the District Court. See
    Matusiewicz Br. 82 (“The defense also presented two
    alternative advisory Guidelines ranges based on other
    Guidelines, but the district court ignored these arguments. The
    defense also argued, and incorporates here, that the cross-
    reference could not be applied on the basis of relevant
    conduct.”). By failing to include this argument in his brief, it
    is waived. See Tunis Bros. v. Ford Motor Co., 
    952 F.2d 715
    ,
    741 (3d Cir. 1991) (“We shall not address the issues raised by
    the plaintiffs on their cross-appeal as the plaintiffs waived them
    by failing to argue them in their briefs. Instead of providing
    argument with respect to their issues, the plaintiffs merely
    referred to their pre- and post-trial briefs. We therefore decline
    to address those issues.” (citations omitted)).
    19
    Although Gonzalez joins this argument, see Gonzalez
    Br. 3, the District Court did not apply this enhancement to her
    sentence.
    72
    [i]f, in a manner creating a substantial risk of
    serious bodily injury, the defendant or a person
    for whose conduct the defendant is otherwise
    accountable . . . knowing or having reasonable
    cause to believe that a person was a law
    enforcement officer, assaulted such officer
    during the course of the offense or immediate
    flight therefrom. . . .
    U.S.S.G. § 3A1.2(c)(1). The defendants’ argument relies on
    their sufficiency of the evidence challenge; that is, they argue
    that this enhancement should not apply because David did not
    know of his father’s plan to kill Belford, and thus, it was not
    reasonably foreseeable to him that law enforcement officers
    might have been harmed during the course of the conspiracy.
    The defendants argue that David’s mere presence in the
    courthouse is an insufficient basis on which to base this
    enhancement.
    The District Court applied this enhancement because
    Thomas shot and wounded two police officers in the course of
    the shootout following his killing of Belford. Additionally, the
    District Court found that conducting a shooting in a courthouse
    lobby, where officers were present, created a reasonably
    foreseeable chance of harm coming to those officers. The jury
    found that David’s actions resulted in the death of Belford. As
    a result, during sentencing, the District Court found that David
    was a knowing participant in his father’s plans on the day of
    the shooting and he had a “specific intent to kill Belford.” App.
    6057. The District Court concluded that in light of the fact that
    David was present in the courthouse lobby, had accompanied
    his father there, and was aware of the events that were about to
    transpire, it was “entirely foreseeable” that there would be a
    73
    potential threat to the numerous uniformed law enforcement
    officers present in the courthouse lobby. App. 6050.
    We agree. In light of the evidence presented at trial and
    before the District Court, the District Court’s application of the
    facts to this enhancement was not an abuse of discretion. It was
    entirely reasonable for the District Court to find that it was
    foreseeable to David that a law enforcement officer might be
    harmed in the events that were about to transpire. Accordingly,
    the District Court did not err in applying this enhancement.
    3. Vulnerable Victim Enhancement
    The defendants next contend that the District Court
    abused its discretion in applying the Vulnerable Victim
    enhancement, U.S.S.G. § 3A1.1(b)(1), because they claim that
    the Government failed to prove the existence of the requisite
    nexus between the vulnerable status of the victims and the
    ultimate success of the crime. The District Court determined
    that there was such a nexus and applied the enhancement,
    finding that Belford’s children were victims of the defendants’
    stalking campaign.
    The Vulnerable Victim enhancement, in relevant part,
    applies “[i]f the defendant knew or should have known that a
    victim of the offense was a vulnerable victim.” U.S.S.G. §
    3A1.1(b)(1). The application note to this enhancement defines
    a “vulnerable victim” as a victim of the defendant’s offense of
    conviction, and any other conduct for which the defendant is
    responsible, that is “particularly susceptible” or “unusually
    vulnerable” to the criminal conduct due to, inter alia, their age,
    physical condition, or mental condition. U.S.S.G. § 3A1.1 cmt.
    n.2. In addition, we require that “the defendant knew or should
    74
    have known of this susceptibility or vulnerability” and that it
    “facilitated the defendant’s crime in some manner.” United
    States v. Iannone, 
    184 F.3d 214
    , 220 (3d Cir. 1999); see also
    United States v. Monostra, 
    125 F.3d 183
    , 190 (3d Cir. 1997)
    (requiring “a nexus between the victim’s vulnerability and the
    crime’s ultimate success” (quoting United States v. Lee, 
    973 F.2d 832
    , 834 (10th Cir. 1992))).
    The District Court did not abuse its discretion in
    applying the Vulnerable Victim enhancement. Belford had
    young children at the time she was killed, who also suffered
    through the defendants’ years-long stalking campaign. As
    young children, they were “particularly susceptible or
    vulnerable to the criminal conduct.” 
    Iannone, 184 F.3d at 220
    ;
    see also United States v. Walker, 
    665 F.3d 212
    , 233 (1st Cir.
    2011) (“Minors are often regarded as especially vulnerable
    victims.”). The defendants certainly knew of the young ages
    of the children to whom they were related. All of Belford’s
    children were victims of the stalking conduct targeted at their
    mother. Indeed, some of them testified at trial that they were
    aware of the stalking campaign — which included false
    allegations that one of the children had been sexually molested
    by her mother — and that they were afraid both for their own
    safety and that of their mother. App. 2654-58. Due to their
    young age, all of these children were more likely to experience
    substantial emotional distress as a result of the defendants’
    conduct; they were powerless to protect themselves from
    allegations of sexual abuse, and as children, were less able to
    defend and protect themselves against any attempted harm
    from the adult defendants. These fears were reasonable in light
    of the fact that two of the defendants, David and Lenore,
    previously had kidnapped the children. Accordingly, the
    75
    District Court did not err in applying of the Vulnerable Victim
    enhancement.20
    4. Eighth Amendment
    Finally, Gonzalez brings an Eighth Amendment
    challenge to her sentence of life imprisonment. We have held
    that “a sentence within the limits imposed by statute is neither
    excessive nor cruel and unusual under the Eighth
    Amendment.” United States v. Miknevich, 
    638 F.3d 178
    , 186
    (3d Cir. 2011). Gonzalez’s life sentence was authorized by
    statute and recommended by the Sentencing Guidelines. See
    18 U.S.C. § 2261(b)(1); U.S.S.G. § 2A1.1; App. 6048. In
    sentencing Gonzales to life imprisonment, the District Court noted
    that she played an instrumental role in the conspiracy against
    Belford, whose death was a reasonably foreseeable consequence
    of the conspiracy. Thus, her life sentence does not violate the
    Eighth Amendment.
    IV. Conclusion
    20
    Additionally, even if both the Official Victim and
    Vulnerable Victim enhancements were applied in error, the
    error would be harmless as the relevant Guidelines range
    would be the same without either enhancement. See United
    States v. Isaac, 
    655 F.3d 148
    , 158 (3d Cir. 2011) (“However,
    the error was completely harmless because even with the one
    point reduction, Isaac would remain in criminal history
    category IV and the same Guideline range would have
    applied.”).
    76
    For the foregoing reasons, and recognizing the
    outstanding work of Judge McHugh, we will affirm in all
    respects.
