    USDC No. 1:18-CR-64-1
    Before BARKSDALE, HAYNES, and WILLETT, Circuit Judges.
    PER CURIAM:*
    Modesto Gonzalez III appeals his convictions for wire fraud and unlawful
    possession of a firearm by a felon. Specifically, Gonzalez argues that his
    statements to law enforcement officers were obtained illegally and should have
    been suppressed. We disagree and affirm.
    * Pursuant to 5TH CIR. R. 47.5, the court has determined that this opinion should not
    be published and is not precedent except under the limited circumstances set forth in 5TH
    CIR. R. 47.5.4.

    I
    In January 2018, state and federal agents executed a federal search
    warrant at Gonzalez’s home. The warrant authorized officers to seize evidence
    of Gonzalez’s two suspected crimes: (1) defrauding illegal aliens by falsely
    claiming to be a federal agent capable of providing immigration assistance in
    exchange for substantial payments, and (2) illegally possessing firearms and
    ammunition as a felon.
    Prior to executing the search warrant, the agents discussed their
    approach. They planned to knock on Gonzalez’s door and wait for a response
    rather than use force to enter. DEA Agent Piekenbrock, who was responsible
    for the impersonation investigation, told the other agents that he “was going
    to try to interview [Gonzalez], but that was obviously no guarantee.”
    Piekenbrock did not intend to provide Gonzalez with a Miranda warning before
    such an interview because he did not plan to arrest him that day.
    Around 7:10 a.m., “between eight and ten” agents arrived at Gonzalez’s
    home to execute the warrant. Their clothing identified them as law
    enforcement, but they were not wearing tactical clothing and did not have their
    weapons drawn.
    Piekenbrock, accompanied by other agents, knocked on the front door.
    Gonzalez answered. After a brief discussion with the agents, he stepped onto
    the porch. Gonzalez was “upset” and “immediately agitated.” He loudly said,
    “[l]et’s get going and let’s just get this over with,” that the agents were “going
    to get [his] family killed,” that the agents should “take [him], and . . . go,” used
    profanity, and appeared to be “about to start a fight.” The agents, by contrast,
    maintained a “[m]easured” and calm tone.
    The agents told Gonzalez that they came to execute a search warrant—
    not an arrest warrant. But Gonzalez was still agitated. Due to his “aggressive
    behavior,” agents handcuffed Gonzalez and temporarily seated him on a chair
    2

    on the porch. Soon thereafter, agents moved Gonzalez to a chair next to the
    stairs leading to the front door of his home to reduce crowding near the
    doorway. Piekenbrock informed Gonzalez that he was not under arrest at that
    time. Gonzalez’s stepfather, who was not handcuffed or otherwise restrained,
    sat next to him on another chair.
    About fifteen minutes after Gonzalez was seated next to the stairs, a
    supervisor informed Gonzalez that if he remained seated and calm, the
    handcuffs would be removed. And then they were. Gonzalez had been
    handcuffed for about twenty minutes. He remained seated near the stairs
    while his home was searched. During the search, agents recovered, among
    other things, a loaded revolver from Gonzalez’s bedroom and two shotguns that
    had been mounted on the living room wall.
    About thirty to forty minutes after the handcuffs were removed,
    Piekenbrock and two other agents asked Gonzalez if he would be willing to
    speak with them. Gonzalez agreed. So, the agents and Gonzalez walked about
    forty feet to Piekenbrock’s vehicle to talk. Piekenbrock sat in the driver’s seat,
    Gonzalez sat in the front passenger seat, and the other two agents sat in the
    back seat. Piekenbrock did not lock the doors. He turned the vehicle and its
    heater on but partially opened the vehicle’s windows. During their
    conversation, the agents’ tone remained “[m]easured,” and “very professional.”
    And the agents never drew their weapons.
    Initially, Piekenbrock reminded Gonzalez that he was not under arrest
    and that they only had a search warrant. Then Piekenbrock questioned
    Gonzalez regarding his impersonation scheme. Gonzalez admitted that he had
    committed “fraud” by taking hundreds of thousands of dollars from illegal
    aliens after falsely promising to get their immigration status adjusted, though
    he framed his actions as “something similar to a loan.” During this roughly
    3
    Case: 19-50725   Document: 00515444245     Page: 4   Date Filed: 06/08/2020
    No. 19-50725
    thirty-five-minute discussion, Gonzalez volunteered information without being
    prompted to do so. He also consented to a search of his cell phone.
    Next, Agent Flores of the Bureau of Alcohol, Tobacco, Firearms and
    Explosives—who was in the back seat of the vehicle—questioned Gonzalez
    about the shotguns and revolver recovered from his home. Gonzalez admitted
    that he had mounted those shotguns on his living room walls and that his
    fingerprints would likely be found on them. Plus, Gonzalez admitted that he
    had bought the loaded revolver from a member of the Aryan Brotherhood.
    At this point, about forty minutes into the interview, Piekenbrock
    “stopped the interview” because Gonzalez’s admission about the revolver
    “changed things” and could result in Gonzalez’s arrest that day. So
    Piekenbrock provided him Miranda warnings. Gonzalez did not request a
    lawyer. Instead, Gonzalez acknowledged that he understood his rights, waived
    them, and agreed to continue the questioning. This post-Miranda interview
    lasted less than fifteen minutes. Gonzalez repeated his statements about the
    impersonation scheme and the recovered firearms. The agents never
    confronted Gonzalez with his pre-warning statements. At no point during the
    pre- or post-warning interview did Gonzalez ask to stop the questioning, to
    leave the vehicle, or for an attorney. And agents repeatedly told Gonzalez that
    he was not under arrest.
    In response to Gonzalez’s post-warning statements, Flores called an
    Assistant U.S. Attorney for legal advice regarding how to proceed and whether
    to arrest Gonzalez for being a felon in possession of a firearm. It was agreed
    that Gonzalez would be criminally charged with illegal firearms possession.
    So, Flores explained to Gonzalez that he would be arrested. Then Gonzalez was
    removed from the vehicle, handcuffed, and returned to the vehicle for transport
    to jail.

    No. 19-50725
    A grand jury charged Gonzalez in a one-count indictment with being a
    felon in possession of a firearm. See 
    18 U.S.C. § 922
    (g)(1). Gonzalez moved to
    suppress all his statements, arguing that the agents had intentionally
    conducted   a   prohibited,   two-step        interrogation   to   avoid   Miranda’s
    requirements. The district court held a hearing at which both Piekenbrock and
    Flores testified. Following this hearing, the district court denied Gonzalez’s
    motion to suppress. The court concluded that (1) Gonzalez was not in Miranda
    custody when the pre-Miranda interview occurred; (2) the agents had not
    deliberately employed a two-step strategy to undermine the warning; and (3)
    Gonzalez’s statements were voluntary.
    After the denial of his motion to suppress, Gonzalez entered into a
    conditional plea agreement with the Government. Gonzalez pled guilty to the
    felon-in-possession charge, and he waived his right to an indictment and pled
    guilty to an information charging wire fraud, in violation of 
    18 U.S.C. § 1343
    .
    He was sentenced to 120 months’ imprisonment. Under the plea agreement,
    Gonzalez reserved the right to appeal the judgment for the limited purpose of
    securing appellate review of the district court’s denial of his motion to
    suppress. Gonzalez timely appealed.
    II
    “In an appeal from a district court’s ruling on a motion to suppress, this
    Court reviews factual findings in support of the ruling under the clearly
    erroneous standard and legal conclusions de novo.” United States v. Cavazos,
    
    668 F.3d 190
    , 193 (5th Cir. 2012). “Our review is particularly deferential where
    denial of the suppression motion is based on live oral testimony because the
    judge had the opportunity to observe the demeanor of the witnesses.” United
    States v. Lim, 
    897 F.3d 673
    , 685 (5th Cir. 2018) (cleaned up). “The evidence is
    viewed in the light most favorable to the party who prevailed in the district
    court.” Cavazos, 
    668 F.3d at 193
    . In this case, that party is the Government.

    No. 19-50725
    “The   question     of    whether        Miranda’s   guarantees    have     been
    impermissibly denied to a criminal defendant, assuming the facts as
    established by the trial court are not clearly erroneous, is a matter of
    constitutional law, meriting de novo review.” United States v. Harrell, 
    894 F.2d 120
    , 122–23 (5th Cir. 1990); see also, e.g., United States v. Chavira, 
    614 F.3d 127
    , 132 n.7 (5th Cir. 2010).
    III
    Gonzalez argues that the district court erred in refusing to suppress the
    statements he made (1) prior to receiving Miranda warnings (because he
    claims the agents conducted a custodial interrogation without giving him
    Miranda warnings), and (2) after receiving Miranda warnings (because he
    claims the agents acted deliberately to circumvent the protections of Miranda
    by conducting a prohibited, two-step interrogation).
    “Miranda    warnings      must      be    administered   prior    to   ‘custodial
    interrogation.’” United States v. Bengivenga, 
    845 F.2d 593
    , 595 (5th Cir. 1988)
    (en banc). But Miranda warnings are not required if an interrogation is non-
    custodial. Oregon v. Mathiason, 
    429 U.S. 492
    , 495 (1977) (per curiam); United
    States v. Garcia, 
    77 F.3d 857
    , 859 (5th Cir. 1996). Gonzalez argues that he was
    in Miranda custody when agents initially interviewed him. But after reviewing
    “[t]he totality of the circumstances surrounding Gonzalez’s interview,” the
    district court determined that he was not in Miranda custody when he made
    his unwarned statements. We find no error in this conclusion.
    To determine whether someone not formally arrested was in Miranda
    custody, we must first “ascertain whether, in light of the objective
    circumstances of the interrogation,” Howes v. Fields, 
    565 U.S. 499
    , 509 (2012)
    (internal quotation marks omitted), “a reasonable person [would] have felt he
    or she was not at liberty to terminate the interrogation and leave.” 
    Id.
     (quoting
    Thompson v. Keohane, 
    516 U.S. 99
    , 112 (1995)) (internal quotation marks

    omitted). In other words, we must determine whether “a reasonable person in
    the suspect’s position would have understood the situation to constitute a
    restraint on freedom of movement of the degree which the law associates with
    formal arrest.” Bengivenga, 
    845 F.2d at 596
    . “The reasonable person through
    whom [a court is to] view the situation must be neutral to the environment and
    to the purposes of the investigation . . . .” 
    Id.
    “[W]hen analyzing whether an individual was or was not in custody,” we
    have “repeatedly considered certain key details,” such as (1) “the location of
    the questioning,” (2) “the amount of restraint on the individual’s physical
    movement,” (3) any “statements made by officers regarding the individual’s
    freedom to move or leave,” (4) “the accusatory, or non-accusatory, nature of the
    questioning,” and (5) “the length of the questioning.” United States v. Wright,
    
    777 F.3d 769
    , 775 (5th Cir. 2015) (collecting cases).
    If the court concludes that “an individual’s freedom of movement” was so
    “curtailed,” then it must “ask[] the additional question whether the relevant
    environment present[ed] the same inherently coercive pressures as the type of
    station house questioning at issue in Miranda.” Howes, 
    565 U.S. at 509
    .
    A
    Here, the district court did not err by first concluding that a reasonable
    person in Gonzalez’s position would not have understood the circumstances in
    which he was interviewed to be a restraint on his or her freedom of movement
    to the degree associated with a formal arrest.
    Turning first to the location of the questioning, Gonzalez was
    interviewed in an agent’s vehicle, as was the defendant in Wright. See 777 F.3d
    at 777. Gonzalez sat in the front seat of the vehicle, not the back seat where
    arrestees usually sit. The interview occurred on Gonzalez’s property and
    within forty feet of his home rather than a secondary, off-site location.
    Gonzalez could see and be seen by his family—meaning the vehicle was subject
    7
    Case: 19-50725     Document: 00515444245      Page: 8   Date Filed: 06/08/2020
    No. 19-50725
    to “public scrutiny.” See id. Thus, the location of the interview suggests that a
    reasonable person in Gonzalez’s position would not have understood the
    situation to constitute a restraint on freedom of movement equivalent to formal
    arrest. See id. at 771, 777 (concluding that defendant was not in custody where,
    while executing a search warrant, two officers interviewed him in a police
    vehicle about thirty feet from his home, defendant sat in the front seat, and
    the vehicle was subject to public scrutiny).
    Similarly, the amount of restraint on Gonzalez’s physical movement also
    suggests that a reasonable person would not equate it with formal arrest. The
    doors of the vehicle were unlocked, and the windows were partially open.
    Notably, Gonzalez was not handcuffed or otherwise restrained during the
    interview. Cf. Chavira, 
    614 F.3d at 134
     (finding that defendant’s freedom of
    movement was severely restrained where agents confiscated her birth
    certificate and state identification and handcuffed her to a chair during the
    interrogation). Although Gonzalez was briefly handcuffed earlier that
    morning, the interview occurred thirty to forty minutes after the handcuffs
    were removed. Unlike in Cavazos, where agents “ran into Cavazos’s bedroom .
    . . and handcuffed him as he was stepping out of bed,” 
    668 F.3d at 192
    , as the
    district court concluded, no evidence suggests “that Gonzalez was handcuffed
    for any reason other than his belligerency.” Gonzalez “calmed down” after
    speaking with his stepfather, so agents removed the handcuffs. He had only
    been handcuffed for about twenty minutes, and agents had informed Gonzalez
    before and while he was handcuffed that he was not under arrest. So, the
    earlier, temporary handcuffing does not negate the lack of physical restraint
    of Gonzalez during the interview. See United States v. Salinas, 543 F. App’x
    458, 465 (5th Cir. 2013) (per curiam) (explaining that “temporary detention by
    itself” does not “automatically rise to the level of custodial interrogation”); see
    also Chavira, 
    614 F.3d at 133
    .
    8
    Case: 19-50725     Document: 00515444245      Page: 9   Date Filed: 06/08/2020
    No. 19-50725
    Likewise, the agents’ statements relating to Gonzalez’s freedom to move
    or leave suggest that a reasonable person would not have found the restrictions
    equivalent to formal arrest. By asking—rather than forcing—Gonzalez to
    participate in the interview, the agents implied that he was free to terminate
    the questioning and leave the vehicle at any time. And before starting the
    interview, Piekenbrock reminded Gonzalez that he was not under arrest. As
    discussed, agents had also informed Gonzalez before and while he was briefly
    handcuffed that he was not under arrest. Although the agents’ statements
    were not as clear as those in Wright, where agents explicitly told the defendant
    he was “free to leave,” 777 F.3d at 771, a reasonable person would have
    interpreted the statements to mean that he was in fact free to leave. And, as
    the district court concluded, “the officers’ actions in telling Gonzalez to remain
    seated in the chair after [the] handcuffs were removed” were not “instructions
    of confinement” or “language of confinement or arrest.” See Salinas, 543 F.
    App’x at 465 (“Even if Salinas were not ‘free to leave,’ that does not mean that
    he was effectively under arrest for the purposes of Miranda.”). Instead, the
    district court explained, “the officers were ensuring that Gonzalez had in fact
    calmed down and were cautioning him not to make sudden movements or again
    become belligerent.” In accordance with our obligation to view the facts in the
    light most favorable to the Government, see Cavazos, 
    668 F.3d at 193
    , we agree
    with this interpretation of the agents’ comments.
    The nature of the questioning also weighs in favor of the interview being
    deemed non-custodial. Rather than engaging in hostile, accusatory questioning
    like the agents in Chavira, the agents here simply, as the district court put it,
    “asked Gonzalez to tell his side of the story and he agreed to do so.” Cf. Chavira,
    
    614 F.3d at 134
     (finding that defendant’s freedom of movement was severely
    restrained where agents questioned her in an increasingly accusatory manner
    for thirty to forty minutes). During their conversation, the agents’ tone
    9
    Case: 19-50725     Document: 00515444245     Page: 10   Date Filed: 06/08/2020
    No. 19-50725
    remained “[m]easured” and “very professional.” As in Wright, the content of
    the interview and the agents’ “tone throughout[] highlights that the
    conversation was as much an opportunity taken by [Gonzalez] to tell his story
    to the officers as it was an opportunity taken by the officers to get information
    from [Gonzalez].” 777 F.3d at 777.
    Finally, the length of the pre-warning interview—forty minutes—does
    not weigh heavily on either side of the scale. See Harrell, 
    894 F.2d at
    124 n.1
    (warning against “[o]verreliance upon the length” of the questioning, as it
    “injects a measure of hindsight into the analysis which we wish to avoid”). The
    interviews in Wright and Cavazos—two cases the parties relied upon—both
    lasted about an hour, and, as the Wright court explained, “the length of the
    questioning weighs in favor of finding that it was custodial.” Wright, 777 F.3d
    at 777; see also Cavazos, 
    668 F.3d at 194
    . But we have previously rejected the
    “broad proposition” that “an hour-long [interview] constitutes a per se custodial
    interrogation.” Harrell, 
    894 F.2d at
    124 n.1. Here, the interview was shorter
    than an hour (about forty minutes) but not so brief as to weigh heavily in the
    opposite direction.
    Gonzalez’s argument leans heavily on what he asserts are similarities
    between the present case and Cavazos. But in addition to any factual
    distinctions, there is a critical difference: We are reviewing a district court’s
    denial of a motion to suppress, meaning we must review the evidence in the
    light most favorable to the Government—not the defendant. See United States
    v. Santiago, 
    410 F.3d 193
    , 197 (5th Cir. 2005); cf. Cavazos, 
    668 F.3d at 191, 195
    (reviewing the district court’s grant of a motion to suppress and evaluating the
    record in the light most favorable to the defendant). Plus, in Cavazos we
    expressly noted that we were addressing “unique circumstances” and not
    making “categorical determinations.” 
    668 F.3d at 195
    .

    No. 19-50725
    Considering all “the circumstances surrounding [Gonzalez’s interview],”
    drawn from the record as seen in the light most favorable to the Government,
    we conclude that “a reasonable person [would] have felt he or she was at liberty
    to terminate the inter[view] and leave.” 
    Id. at 193
     (internal quotation marks
    omitted). Compare Wright, 777 F.3d at 777 (affirming the district court’s
    conclusion that the defendant was not in custody during a pre-Miranda
    interview where seventeen to nineteen law enforcement officers were in and
    around defendant’s home executing a search warrant; officers repeatedly
    assured defendant that he was not under arrest and that he was free to leave;
    and defendant was not physically restrained during the hourlong interview,
    which took place about thirty feet from his home, in a car subject to public
    scrutiny, and the conversation was as much an opportunity taken by defendant
    to tell his story to officers as it was an opportunity taken by officers to get
    information from defendant), and Salinas, 543 F. App’x at 464−65 (finding that
    a reasonable person in defendant’s position would not have considered himself
    under arrest where two federal marshals initially questioned him at his
    apartment complex; he remained subject to public scrutiny; and he was not
    restrained, even though one of the marshals retained defendant’s cell phone
    and testified that defendant was not free to leave once he suspected defendant
    was lying), with Cavazos, 
    668 F.3d at 194
     (affirming the district court’s finding
    that a reasonable person would believe he was not “at liberty to terminate the
    interrogation and leave” where more than a dozen agents entered his home,
    handcuffed him as he stepped out of bed, separated him from his family, and
    two federal agents interrogated him for at least an hour—during which time
    they observed his restroom use and only allowed him to make a phone call in
    such a way that agents could listen to the conversation), and Chavira, 
    614 F.3d at 134
     (finding that defendant’s freedom of movement was severely restrained
    where agents confiscated her birth certificate and state identification; moved
    11

    her to a windowless, 14-by-10-foot secure room; handcuffed her to a chair;
    questioned her in an increasingly accusatory manner for thirty to forty
    minutes; and detained the minor in her care).
    Because this “freedom-of-movement test identifies . . . a necessary . . .
    condition for Miranda custody,” Maryland v. Shatzer, 
    559 U.S. 98
    , 112 (2010),
    we conclude that Gonzalez was not in Miranda custody when he made his
    unwarned statements.
    B
    But even if Gonzalez’s freedom of movement were so limited, the district
    court determined that the environment in which he was interviewed did not
    “present[] the same inherently coercive pressures as the type of station house
    questioning at issue in Miranda.” Howes, 
    565 U.S. at 509
    . And the district
    court did not err in reaching this conclusion.
    About forty minutes after the handcuffs were removed, Gonzalez
    voluntarily agreed to speak with the agents and walked to Piekenbrock’s
    vehicle. As the district court noted, “[n]o officer ordered Gonzalez to get into
    the vehicle, and no officer drew a gun.” During the interview, Gonzalez sat “in
    the front passenger seat of [the] law-enforcement vehicle on [his] property and
    within 40 feet of his residence, with the vehicle’s windows partly down, and
    without restraint.” And the agents maintained a “respectful and calm” tone.
    Put simply, the environment was not inherently coercive; as the district court
    noted, “Gonzalez willingly agreed to speak with officers, agreed to get in the
    vehicle, never asked to leave, and never asked for a lawyer.”
    A reasonable person could certainly be “startl[ed] and intimidat[ed]” by
    eight to ten agents searching his or her home, but that’s not enough to
    constitute station-house-level coercive pressure. Wright, 777 F.3d at 777

    around [defendant]’s home was startling and intimidating” but still concluding

    that, based on “the totality of the circumstances,” the interrogation was non-
    custodial). So, considering the totality of the circumstances, the environment
    where the in-car interview occurred did not “present[] the same inherently
    coercive pressures as the type of station house questioning at issue in
    Miranda.” Howes, 
    565 U.S. at 509
    . Consistent with the district court’s findings,
    there was “no evidence of coercive behavior or coercive questioning by the
    officers.” As such, Gonzalez was not in Miranda custody during the pre-
    warning interview.
    In sum, Gonzalez was not in Miranda custody when he was interviewed
    because a reasonable person in his position would not have viewed the
    situation as a restraint on his freedom of movement equal to a formal arrest,
    and the interview environment was not tantamount to a station house
    interrogation. Thus, we affirm the district court on this issue.
    IV
    But assuming arguendo that the pre-warning interview occurred while
    Gonzalez was in Miranda custody, we address Gonzalez’s next argument: that
    his post-warning statements should be suppressed because the agents acted
    deliberately to circumvent the protections of Miranda by conducting both a
    pre-warning and post-warning interrogation. We find no error in the district
    court’s denial of Gonzalez’s motion to suppress and finding that the agents did
    not engage in a prohibited, two-step interrogation. So any error in admitting
    Gonzalez’s pre-warning statements would be harmless.
    Where a “two-step interrogation technique was used in a calculated way
    to undermine the Miranda warning,” “postwarning statements that are related
    to the substance of prewarning statements must be excluded unless curative
    measures are taken before the postwarning statement is made.” Missouri v.

    see also, e.g., United States v. Nunez-Sanchez, 
    478 F.3d 663
    , 668 (5th Cir. 2007).
    This forbidden, two-step strategy “involves an interrogator relying on the
    defendant’s prewarning statement to obtain the postwarning statement used
    against [him] at trial, by confronting the defendant with [his] inadmissible
    prewarning statements and pushing [him] to acknowledge them.” United
    States v. Delgado-Arroyo, 358 F. App’x 530, 532 (5th Cir. 2009) (per curiam)
    (cleaned up).2
    If we determine that agents employed a calculated strategy to evade
    Miranda with the proscribed two-step interrogation, we must determine if they
    took curative measures “to ensure that a reasonable person in the suspect’s
    situation would understand the import and effect of the Miranda warning and
    of the Miranda waiver.” Seibert, 
    542 U.S. at 622
     (Kennedy, J., concurring in
    the judgment).3 But, if we conclude that agents used no such tactic, the
    admissibility of the warned statements is “governed by the principles of
    Elstad.” Id.; see also infra Part IV(B) (discussing Elstad).
    Seibert’s holding is set forth “in Justice Kennedy’s opinion concurring in the
    1
    judgment.” United States v. Courtney, 
    463 F.3d 333
    , 338 (5th Cir. 2006).
    2  For example, in Seibert, “[t]he postwarning interview resembled a cross-
    examination. The officer confronted the defendant with her inadmissible prewarning
    statements and pushed her to acknowledge them. See App. 70 (‘[Patrice], didn’t you tell me
    that he was supposed to die in his sleep?’).” Seibert, 
    542 U.S. at 621
     (Kennedy, J., concurring
    in the judgment).
    3 “For example, a substantial break in time and circumstances between the
    prewarning statement and the Miranda warning may suffice in most circumstances, as it
    allows the accused to distinguish the two contexts and appreciate that the interrogation has
    taken a new turn. . . . Alternatively, an additional warning that explains the likely
    inadmissibility of the prewarning custodial statement may be sufficient.” Seibert, 
    542 U.S. at 622
     (Kennedy, J., concurring in the judgment) (internal citation omitted).

    A
    So, to start, we must determine whether agents used the two-step
    interrogation strategy Seibert prohibits. Gonzalez argues that the agents
    deliberately waited to give Miranda warnings until he had made an
    “incriminating”     statement.   True,       “Piekenbrock’s    operational     plan
    contemplated that Gonzalez would be interviewed by officers but not
    Mirandized,” and that Gonzalez might “be arrested if firearms were found in
    his home.” But, as the district court found, the “officers did not determine that
    Gonzalez would be arrested until after Gonzalez admitted to buying a revolver
    from the Aryan Brotherhood and after the questioning officers presented the
    facts and circumstances to a federal prosecutor for review.” Gonzalez made
    incriminating statements about his impersonation scheme, but those were
    insufficient “to cause him to be arrested that day.” And Piekenbrock testified
    that Gonzalez’s statement about purchasing the revolver “changed things,”
    ultimately leading the agent to Mirandize Gonzalez. So, rather than engaging
    in a two-step interrogation premised on deceit, the record suggests that agents
    merely responded to evidence—including Gonzalez’s voluntary statements—
    acquired during execution of the search warrant and acted in accordance with
    legal counsel. Gonzalez offered no evidence to the contrary.
    Plus, the circumstances, nature, and tone of the questioning do not
    suggest “that coercion or other improper tactics were used.” Nunez-Sanchez,
    
    478 F.3d at 668
    . Rather, after providing Gonzalez with Miranda warnings, the
    agents continued to speak with him in a “very professional” tone. And the
    record indicates that, as in Lim, “the agents did not act with aggressiveness or
    hostility,” Lim, 897 F.3d at 692 (internal quotation marks omitted), which
    undercuts any argument that the agents confronted Gonzalez with his pre-
    warning statements and pushed him to acknowledge them.
    15

    No. 19-50725
    Gonzalez contends that the post-Miranda questioning was “repetitive”
    and that agents obtained “no new information after the warning,” thus
    showing a deliberate scheme to undermine Miranda. But even if agents
    questioned Gonzalez about the same subjects pre- and post-Miranda, that does
    not prove that they “confront[ed]” him with his earlier statements and
    pressured him to acknowledge them. See Delgado-Arroyo, 358 F. App’x at 532.
    Indeed, the record shows that agents did not “confront[]” Gonzalez “with the
    statements that had been made earlier”; Piekenbrock testified that there was
    no “discussion of the statements that were made” before Gonzalez was provided
    Miranda warnings. Thus, the district court did not err by determining that the
    agents did not employ the proscribed two-step strategy when interviewing
    Gonzalez.4
    B
    Because agents did not use the proscribed two-step strategy, the
    admissibility of the warned statements is “governed by the principles of
    Elstad.” Seibert, 
    542 U.S. at 622
     (Kennedy, J., concurring in the judgment). As
    the Supreme Court explained in Elstad, the “subsequent administration of
    Miranda warnings to a suspect who has given a voluntary but unwarned
    statement ordinarily should suffice to remove the conditions that precluded
    admission of the earlier statement.” Oregon v. Elstad, 
    470 U.S. 298
    , 314 (1985).
    “In such circumstances,” the Court explained, “the finder of fact may
    reasonably conclude that the suspect made a rational and intelligent choice
    whether to waive or invoke his rights.” 
    Id.
     “Under Elstad, the relevant inquiry
    4 Consequently, no curative measures were necessary. So although Gonzalez is correct
    that the agents did not employ curative measures after providing Gonzalez Miranda
    warnings, that is irrelevant here.
    16

    is whether, in fact, the second statement was also voluntarily made.” United
    States v. Courtney, 
    463 F.3d 333
    , 338 (5th Cir. 2006) (cleaned up).
    “[I]n evaluating the voluntariness of [a suspect’s] statements,” “the
    finder of fact must examine the surrounding circumstances and the entire
    course of police conduct with respect to the suspect.” Elstad, 
    470 U.S. at 318
    .
    The Supreme Court has rejected a “presum[ption of] coercive effect where the
    suspect’s initial inculpatory statement, though technically in violation of
    Miranda, was voluntary.” 
    Id.
     Rather, “[a] statement is involuntary if the
    tactics employed by law enforcement officials constitute a Fifth Amendment
    due process violation and are so offensive to a civilized system of justice that
    they must be condemned.” Lim, 897 F.3d at 692 (cleaned up). And the
    Government has the burden to prove that Gonzalez voluntarily waived his
    Miranda rights. See Berghuis v. Thompkins, 
    560 U.S. 370
    , 382 (2010).
    Here, the district court correctly determined “that Gonzalez’s post-
    Miranda statements were voluntarily made” and noted that Gonzalez did not
    present any evidence otherwise. Gonzalez did not even argue in his opening
    appellate brief that his post-warning statements were constitutionally
    involuntary, so the argument is forfeited. Procter & Gamble Co. v. Amway
    Corp., 
    376 F.3d 496
    , 499 n.1 (5th Cir. 2004) (explaining that “[f]ailure
    adequately to brief an issue on appeal constitutes [forfeiture] of that argument”
    and finding that argument was forfeited where a party “fail[ed] to raise it in
    its opening brief”). And even if Gonzalez hadn’t forfeited the argument, it

    would fail.5 We affirm the district court’s denial of Gonzalez’s motion to
    suppress his post-warning statements.6
    *      *      *
    For these reasons, we AFFIRM. And we DENY Gonzalez’s motion for bail
    pending appeal as moot.
    5  As the district court emphasized, “Piekenbrock testified that Gonzalez stated he
    understood his rights and agreed to waive them and continue the interview.” Plus,
    considering the totality of the circumstances of the interview and the agents’ conduct, we
    conclude that Gonzalez’s post-warning statements were voluntary rather than coerced.
    6   As discussed, the district court properly admitted Gonzalez’s pre-warning
    statements. But even if the district court had erred, because Gonzalez’s pre- and post-
    Miranda statements were substantively the same, any error in admitting Gonzalez’s pre-
    Miranda statements was harmless. Cf. United States v. Boche-Perez, 
    755 F.3d 327
    , 342 (5th
    Cir. 2014).
