    Before MANION, BRENNAN, and JACKSON-AKIWUMI, Circuit
    Judges.
    BRENNAN, Circuit Judge. While on federal supervised
    release, John Johnson agreed to cooperate with local police.
    Federal prosecutors did not object, and his cooperation was
    allowed by a federal judge. Later, federal drug charges were
    brought against Johnson, which he argued should be dis-
    missed under the cooperation agreement. But there was no
    federal non-prosecution agreement, and an agency theory did

    not bind federal authorities under the cooperation agreement.
    The Government also did not suppress favorable evidence
    material to Johnson’s defense. So, we affirm.
    I
    John Johnson was convicted of a series of state drug
    charges and received a lengthy sentence. He later pleaded
    guilty to a federal offense for distributing cocaine, which re-
    sulted in a 60-month prison sentence. In 2011, he was released
    from federal custody under supervised release. But on two
    separate occasions in 2014, Johnson sold cocaine to a Drug En-
    forcement Administration confidential informant. At that
    time, he was not prosecuted for either drug offense.
    The Proposed Cooperation Agreement. Sixteen months later,
    Jonathan Jones and David Dailey, two Decatur, Illinois Police
    Department officers, approached Johnson on the street. The
    officers told Johnson they knew about his 2014 drug transac-
    tions and showed him incriminating evidence. They pro-
    posed that Johnson covertly assist local law enforcement in
    providing information about illegal drug activity and various
    crimes. Johnson agreed to cooperate in exchange for leniency,
    although he and the officers understood that the proposed
    agreement would need to be approved by the federal govern-
    ment in accord with a condition of Johnson’s federal super-
    vised release.
    The proposed agreement was not reduced to writing, and
    the parties now dispute its terms. According to Johnson, he
    reasonably believed that the officers promised him immunity
    from all prosecution for the 2014 drug transactions, including
    federal immunity. The Government denies that anyone ever
    promised Johnson immunity from federal prosecution.
    No. 20-3272                                                  3
    After Johnson agreed to cooperate, Decatur officers con-
    tacted his federal probation officer, Gwen Powell, to request
    federal permission for Johnson to cooperate. According to a
    violation memorandum Powell later prepared for a revoca-
    tion proceeding, the officers “requested permission for [John-
    son] to cooperate with them and in exchange, no charges
    would be filed against the offender.”
    Before seeking permission from the district court, Powell
    informed Assistant United States Attorneys Jason Bohm and
    Eugene Miller of the proposed cooperation agreement and re-
    quested their position. Powell emailed Bohm that “Johnson
    wants to cooperate and work with Decatur PD,” to which
    Bohm replied that he had “no objection.” Bohm also for-
    warded Powell’s email request to Miller, who replied he
    “ha[d] no objection to John Johnson’s request to cooperate
    with the Decatur Police Department.”
    After receiving approval from Bohm and Miller, Powell
    emailed Judge Harold A. Baker of the United States District
    Court for the Central District of Illinois. Bohm and Miller re-
    ceived a copy of this correspondence. Powell’s email in-
    formed Judge Baker of Johnson’s two controlled drug buys in
    2014, and then stated:
    Decatur police officers want offender Johnson to
    cooperate with them and work as a confidential
    information. [sic] In exchange, Macon County
    will not likely charge and/or convict him for the
    drug related offenses in 2014 and will not con-
    vict him for a recent Driving with a Revoked Li-
    cense. I have discussed this matter with AUSA
    Bohm and AUSA Miller. Neither of us have any
    objections to Johnson cooperating with Decatur

    PD. As a condition of offender Johnson’s super-
    vised release, he must not enter into any agree-
    ment to act as an informer or a special agent of
    a law enforcement agency without the permis-
    sion of the court. Please advise is [sic] you agree
    for Johnson to cooperate with the Decatur Police
    Department as a confidential informant.
    In response, Judge Baker instructed Powell to “[g]o ahead and
    allow” Johnson to cooperate with the Decatur Police Depart-
    ment. At no point during Powell’s communications with the
    United States Attorney’s Office or Judge Baker did she ever
    request, or receive approval for, a federal non-prosecution
    agreement.
    After receiving Judge Baker’s approval, Jones and Powell
    separately contacted Johnson to inform him that the federal
    government had approved the proposed agreement and that
    Johnson’s cooperation could begin.
    The Written Agreement. Approximately two months later,
    Jones approached Johnson with a written Confidential In-
    formant Agreement. According to Johnson, Jones stated that
    the document was a “formality” to memorialize in writing
    “the agreement we had already made and that had already
    been approved.” The three-page document did not mention a
    federal non-prosecution agreement. It states that “[t]he Deca-
    tur Police Department/Macon County Sheriff’s Office does
    not promise or agree to any consideration by a prosecutor or
    a court in exchange for [Johnson’s] cooperation,” and that
    Johnson had “no immunity or protection from investigation,
    arrest or prosecution” for any unauthorized conduct. Johnson
    also agreed “not to participate in any criminal activity.”
    No. 20-3272                                                             5
    Johnson testified that he signed the agreement without
    reading it, relying on Jones’s representations that it was only
    a formality. Johnson also claimed that Jones did not review
    the terms of the written agreement with him prior to signing
    it. Jones disputed this, testifying at Johnson’s revocation pro-
    ceeding that he went over the form “line-by-line” with John-
    son before they each signed it. 1
    Federal Prosecution for the 2014 Drug Offenses. Twice in 2016,
    Johnson tested positive for cocaine and thus violated the
    terms of his federal supervised release and cooperation agree-
    ment. He also admitted to not being honest with law enforce-
    ment about a previously undisclosed cocaine supplier in
    Chicago, from whom Johnson had purchased several kilo-
    grams of cocaine in 2016. The Decatur Police Department later
    acquired information that suggested Johnson was continuing
    to engage in cocaine trafficking while cooperating with offic-
    ers.
    In February 2017, the district court issued a warrant for
    Johnson’s arrest for violating his conditions of supervised re-
    lease. A federal grand jury indicted Johnson on two counts of
    distributing a controlled substance related to the drug deliv-
    eries in 2014.
    Nearly two years later, Johnson moved to dismiss the in-
    dictment. He argued he had received federal immunity from
    1 Johnson was not represented by counsel at this meeting about the written
    Confidential Informant Agreement or previously when Decatur police
    first requested his cooperation in late 2015. Such representation might
    have helped resolve any genuine uncertainties about the scope of an
    agreement and its ramifications.
    6                                                             No. 20-3272
    prosecution for the 2014 drug offenses through his coopera-
    tion agreement with the Decatur Police Department. He relied
    on his affidavit and Powell’s memo, in which she wrote that
    Decatur officers had told her “no charges would be filed
    against the offender” in exchange for his cooperation.
    Johnson also filed a motion to permit Powell to testify at
    an evidentiary hearing and to produce her records, which in-
    cluded Powell’s notes taken while supervising Johnson and
    related emails. The Government did not object. After review-
    ing Powell’s records in camera, the court provided the parties
    with redacted copies, which included the emails between
    Powell and Decatur officers, Bohm, Miller, and Judge Baker.
    The court permitted Johnson to subpoena Powell to appear at
    an evidentiary hearing.
    The day before that hearing, Johnson filed a second mo-
    tion to dismiss the indictment, this time as a discovery sanc-
    tion. Johnson asserted the Government had not complied
    with his discovery request to produce documents connected
    with his cooperation agreement. He pointed to the redacted
    emails the court provided to the parties from Powell’s rec-
    ords, contending the Government should have produced its
    copies of the emails in response to previous discovery re-
    quests. 2 Notwithstanding the late production of Powell’s
    emails, Johnson’s counsel informed the court that the defense
    was ready to proceed.
    On January 7, 2020, the district court held an evidentiary
    hearing, at which Powell and Johnson testified. In response to
    questions about her memo, in which she had written that “no
    2 The United States Attorney’s Office could not locate its copy of the emails
    because of a three-year retention procedure.
    No. 20-3272                                                             7
    charges would be filed against the offender” in exchange for
    Johnson’s cooperation, Powell clarified that she understood
    the Decatur officers had promised Johnson prosecutorial im-
    munity “by the state or the county if he fully cooperated.”
    When asked whether she ever recalled telling a defendant “if
    they cooperated they would never be charged with a federal
    offense,” Powell said she “[n]ever told them that.” And when
    asked if she ever told this to Johnson, Powell responded no.
    Johnson, on the other hand, testified that Powell had told
    him he would not face a federal “sanction[]” if he cooperated
    with the Decatur Police Department. Johnson also claimed
    that during their initial encounter, Jones had said Johnson
    would not face federal prosecution as part of the unwritten
    cooperation agreement. Johnson admitted that he had not
    spoken to anyone from the United States Attorney’s Office
    about a cooperation agreement, and he testified he had signed
    the written Confidential Informant Agreement without read-
    ing it.
    After Johnson’s testimony, the district court concluded it
    “simply cannot find that there was a federal agreement not to
    prosecute.” The court reasoned that, at most, “this record
    would support … a finding that the assistant U.S. attorneys
    had no problem supporting his cooperating with the state au-
    thorities. But … there’s nothing in this record … to suggest
    that there was a federal agreement not to prosecute [Johnson]
    in Federal Court.” On this basis, the court denied Johnson’s
    first motion to dismiss. 3 Johnson’s second motion to dismiss,
    which alleged the discovery violation, remained pending.
    3The United States attempted to call Jones to testify and present evidence
    concerning Johnson’s violations of the cooperation agreement, but
    8                                                             No. 20-3272
    After the evidentiary hearing, Johnson sought further
    discovery relating to his cooperation agreement. The Govern-
    ment objected but provided Johnson with additional docu-
    ments on March 13, including twelve pages of internal United
    States Attorney’s Office emails reviewed by the district court
    in camera. The emails referred to Johnson’s cooperation with
    the Decatur Police Department, along with Miller and Judge
    Baker’s approval of the cooperation. But in response to inquir-
    ies about a federal non-prosecution agreement, Powell told
    the United States Attorney’s Office in an email that, “[a]s for
    [sic] as I know, there was no agreement with the federal gov-
    ernment that he not be prosecuted for the [2014] drug distri-
    butions.”
    Johnson insisted these additional emails contained rele-
    vant information pertaining to a federal non-prosecution
    agreement. So with court permission, he supplemented his
    second motion to dismiss for discovery sanctions, and he
    moved for reconsideration of the ruling on his first motion to
    dismiss based on a federal non-prosecution agreement.
    At a hearing on April 16, 2020, the district court considered
    both motions. Johnson’s counsel confirmed the court’s belief
    that the record contained no “statements by an assistant U.S.
    attorney … that they’re offering immunity to him on the
    Johnson objected. The district court sustained the objection on the grounds
    that the issue of Johnson’s compliance with the Confidential Informant
    Agreement was moot in view of the court’s finding that no federal prose-
    cutorial immunity existed. Jones later testified in a separate proceeding for
    Johnson’s revocation of supervised release, where he recounted going
    over the written agreement “line-by-line” with Johnson and denied that
    he had told Johnson he would receive federal immunity in contravention
    of the written agreement.
    No. 20-3272                                                    9
    federal charges.” The court concluded that “the record in this
    case as it presently exists clearly indicates that … the federal
    government did not, either impliedly or expressly, make an
    agreement with the defendant that he would not be prose-
    cuted. It’s just simply not there.” While the court again
    acknowledged Powell’s memo that stated Johnson would not
    be prosecuted, the court recognized that Powell later “clari-
    fied and refuted” the suggestion that this included federal im-
    munity. The court further observed that “the probation officer
    can’t bind the U.S. Attorney anyway.” In addition to finding
    that Johnson was not offered federal immunity, the court also
    ruled that Johnson could not have “reasonably … believed
    that the federal government was saying that they were not go-
    ing to prosecute him.” So, the district court upheld its denial
    of the first motion to dismiss.
    The court also denied Johnson’s second motion to dismiss
    as a discovery sanction. The cited email communications
    “work[] against the defendant, not in his favor,” the court
    found, and “in any event, the defense has it now.” As such,
    the court determined the United States had not committed a
    Brady violation.
    After his motions were denied, Johnson entered condi-
    tional guilty pleas to each of the drug offenses in the two-
    count indictment. Johnson reserved his right to appeal the
    district court’s denial of his two motions to dismiss the indict-
    ment. The district court sentenced Johnson to 180 months’ im-
    prisonment.

    Johnson argues he was promised immunity from federal
    prosecution as part of the unwritten cooperation agreement
    with the Decatur Police Department, so the district court
    erred in denying his first motion to dismiss the indictment.
    “We review de novo the denial of a motion to dismiss an in-
    dictment and the court’s factual findings for clear error.”

    As the parties acknowledge, and as this court has long rec-
    ognized, only federal prosecutors can grant a defendant in-
    formal immunity from federal prosecution. 4 See United States

    was not a party to [the] plea agreement” and authorities from

    The United States Attorney’s Office did not directly or in-
    directly authorize a federal non-prosecution agreement here.
    Johnson admits he did not speak to anyone from the United
    States Attorney’s Office about his cooperation. In fact, the pol-
    icy of the United States Attorney’s Office for the Central Dis-
    trict of Illinois prohibited the authorization of transactional
    immunity deals. 5 Johnson nonetheless insists that the string
    of emails between federal prosecutors and Powell show the
    Government acquiesced to a federal non-prosecution agree-
    ment.
    5 Transactional immunity precludes prosecuting an offense, while use im-
    munity precludes the use of a defendant’s proffered statement against
    him. United States v. Eliason,

    The emails do not show a federal agreement, and ex-
    pressly state that Johnson’s cooperation was with local au-
    thorities. In response to Powell’s email stating that “Johnson
    wants to cooperate and work with Decatur PD,” Bohm replied
    he had “no objection.” Miller was specific: “I have no objec-
    tion to John Johnson’s request to cooperate with the Decatur
    Police Department.” Bohm and Miller were copied on an
    email from Powell to Judge Baker, which stated that in ex-
    change for Johnson’s cooperation, “Macon County will not
    likely charge and/or convict him for the drug related offenses
    in 2014.” And in advance of trial, when the United States At-
    torney’s Office asked Powell if she knew of any non-prosecu-
    tion agreement between a federal prosecutor and Johnson,
    Powell stated “there was no agreement with the federal gov-
    ernment that he not be prosecuted for the drug distributions.”
    As these emails show, Powell did not seek approval for a
    federal non-prosecution agreement, and the United States At-
    torney’s Office did not expressly or implicitly suggest that
    Johnson would receive federal immunity. Johnson conflates
    federal approval of a Decatur Police Department cooperation
    agreement involving state and county immunity with consent
    to a federal non-prosecution agreement. But the two are dis-
    tinct, and there is no evidence that the United States Attor-
    ney’s Office approved the latter.
    Without the Government actually granting federal im-
    munity, Johnson is left arguing that the federal government is
    bound to the cooperation agreement under an agency theory.
    Recall that Powell and Jones had no actual authority to bind
    the United States Attorney’s Office. As a probation officer,
    Powell was an employee of the federal judiciary, which lacks
    authority to bind federal prosecutors to a non-prosecution
    No. 20-3272                                                   13
    agreement. See United States v. Hollins, 
    847 F.3d 535
    , 541 (7th
    Cir. 2017). State and county officials like Jones also lack such
    authority, as “the federal government [is] not bound by an
    agreement made by the defendant and state agents.” Staten v.
    Neal, 
    880 F.2d 962
    , 966 (7th Cir. 1989).
    Johnson invokes the “doctrine of inherent agency,” citing
    Neal. According to Johnson, he reasonably believed he would
    receive federal immunity because Jones and Powell “ex-
    pressly told him” so.
    Johnson’s theory fails for three reasons. First, there is in-
    sufficient evidence to overturn the district court’s findings
    that Johnson was not offered, and could not have reasonably
    believed he was offered, federal immunity. Powell and Jones
    each testified they did not promise Johnson immunity from
    federal prosecution. No federal prosecutor spoke with John-
    son about a federal non-prosecution agreement. The emails
    between Powell and the United States Attorney’s Office are
    devoid of any request for, or approval of, any such agreement.
    And Johnson signed the three-page Confidential Informant
    Agreement, which expressly stated he would not receive im-
    munity from prosecution.
    In addition to his affidavit, Johnson relies on Powell’s
    memo, in which she recounts that Decatur officers told John-
    son “no charges would be filed against the offender” in
    exchange for his cooperation. But Powell later testified she
    understood that Decatur officers told Johnson he would re-
    ceive immunity “by the state or the county,” not the United
    States. Without more, we are not left with a “definite and firm
    conviction” that the district court erred in determining John-
    son was not offered, and could not have reasonably believed
    14                                                         No. 20-3272
    he was offered, federal immunity. Elizondo, 21 F.4th at 473
    (quoting Blake, 965 F.3d at 558).
    Second, inherent agency authority does not apply here. As
    we stated in Neal, “[t]he doctrine of inherent agency authority
    presupposes that one party is an agent of another party, the
    principal, and that it is this agency relationship which causes
    the third party to assume that the words and actions of the
    agent are also those of the principal.” 
    880 F.2d at 965
    . Neither
    Powell nor Jones was an agent of the United States Attorney’s
    Office because federal prosecutors did not approve a federal
    immunity deal, vest Powell and Jones with authority to make
    one, or even request that Powell or Jones relay their non-ob-
    jection of the Decatur cooperation agreement to Johnson. 6 The
    principle of apparent authority 7 does not help Johnson either
    6    At most, Powell might have acted as an agent of the district court.
    Powell was a federal judicial employee, the district court held exclusive
    authority to approve Johnson’s cooperation while on federal supervised
    release, and Judge Baker instructed Powell to “[g]o ahead and allow”
    Johnson to cooperate with the Decatur Police Department—an instruction
    that could be viewed as Judge Baker authorizing Powell to communicate
    his approval of the agreement to Johnson.
    But approval by the United States Attorney’s Office of Johnson’s co-
    operation was not necessary, and neither Bohm nor Miller asked Powell
    to relay their non-objection of the agreement to Johnson. Because the
    United States Attorney’s Office did not manifest assent to Powell for her
    to act on its behalf, no agency relationship existed between them. See RE-
    STATEMENT (THIRD) OF AGENCY § 1.01 (AM. L. INST. 2006).
    7 Although Johnson does not explicitly argue for apparent authority, his
    arguments under inherent authority are similar because they are based on
    what Jones and Powell told him. Both parties rely on Lilly, which dealt
    with apparent authority. 810 F.3d at 1210. And the Restatement Third of
    Agency abandoned use of “inherent agency power” because the concept
    was encompassed by other doctrines, including apparent authority, which
    No. 20-3272                                                         15
    because he had no contact with any federal prosecutor and
    did not interpret manifestations by the United States Attor-
    ney’s Office as evidence that Powell or Jones were authorized
    to offer him federal immunity. See RESTATEMENT (THIRD) OF
    AGENCY § 2.03 cmt. c (AM. L. INST. 2006) (“A belief that results
    solely from the statements or other conduct of the agent, un-
    supported by any manifestations traceable to the principal,
    does not create apparent authority.”).
    Third, even if Powell or Jones possessed inherent agency
    authority or apparent authority, neither doctrine is sufficient
    “to bind the federal government to a contract; unless the agent
    had actual authority, any agreement is ineffectual.” Urso v.
    United States, 
    72 F.3d 59
    , 60 (7th Cir. 1995); see also United States
    v. Long, 
    511 F.2d 878
    , 881 (7th Cir. 1975) (“‘The government is
    not bound by acts of persons who never have been … its
    agents.’ This remains horn book law.” (quoting Newman v.
    United States, 
    28 F.2d 681
    , 682 (9th Cir. 1928))); RESTATEMENT
    (THIRD) OF AGENCY § 2.03 cmt. g (AM. L. INST. 2006) (“The doc-
    trine of apparent authority generally does not apply to sover-
    eigns …. [T]hird parties who deal with national governments,
    quasi-governmental entities, states, counties, and municipali-
    ties take the risk of error regarding the agent’s authority to a
    greater degree than do third parties dealing through agents
    with nongovernmental principals.”). “If the rule were other-
    wise, a minor government functionary hidden in the recesses
    of an obscure department would have the power to prevent
    the prosecution of a most heinous criminal simply by prom-
    ising immunity in return for the performance of some act
    which might benefit his department.” Lilly, 810 F.3d at 1211
    suggests that discussion of apparent authority is appropriate. RESTATE-
    MENT (THIRD) OF AGENCY   § 2.01 cmt. b (AM. L. INST. 2006).
    16                                                No. 20-3272
    (quoting Dresser Indus., Inc. v. United States, 
    596 F.2d 1231
    ,
    1236–37 (5th Cir. 1979)). A contrary rule would also risk vio-
    lating federalism principles and the separation of powers, as
    states and non-executive federal officials could bind the Exec-
    utive Branch to agreements it alone has the power to make.
    And because there is no actual authority here, any inherent or
    apparent authority assertion is ineffectual.
    On the topic of agency and the authority to grant federal
    immunity, both parties invite us to examine United States v.
    Lilly, 
    810 F.3d 1205
     (10th Cir. 2016). There, the defendant ar-
    gued she was immune from federal prosecution because Wy-
    oming and DEA authorities purportedly promised her im-
    munity in exchange for her cooperation. 810 F.3d at 1209–10.
    Assuming the defendant was promised such immunity, the
    court nevertheless held that “neither agency had the authority
    to promise Ms. Lilly federal immunity, and thus any pur-
    ported agreement is unenforceable against the United States.”
    Id. at 1210. “This rule,” the court explained, “is grounded in
    principles of sovereignty and prosecutorial discretion.” Id. at
    1212.
    Johnson responds that Lilly discussed a “fundamental-
    fairness exception” to this rule, which has been recognized by
    some federal circuit courts. Id. at 1215–16 That exception
    binds the United States Attorney to a non-prosecution agree-
    ment, even when the United States Attorney was not a party
    to the agreement, “when the government’s noncompliance
    with an unauthorized promise would render a prosecution
    fundamentally unfair.” Id. at 1215 (quoting Flemmi, 
    225 F.3d at
    88 n.4). But this exception is “‘narrow’” and “‘seldom-
    seen,’” and “exclude[s] from its ambit the mine-run (i.e., typ-
    ical) case.” Id. at 1216 (quoting Flemmi, 
    225 F.3d at
    88 n.4).
    No. 20-3272                                                  17
    These mine-run cases include instances where a defendant
    “complains that investigators made unfulfilled promises that
    the defendant would not be prosecuted or would receive
    other favorable treatment relative to potential criminal
    charges if the defendant truthfully disclosed information re-
    garding an investigation … or actively assisted the investiga-
    tors in efforts aimed at catching other possible criminals”—
    the exact facts of this case. Id. at 1217. “Accordingly, because
    [Johnson’s] case is mine-run, it is not a suitable candidate for
    application of the fundamental-fairness exception.” Id.
    Similarly, Johnson points to this court’s decision in United
    States v. Cahill, which stated that “[t]he prosecution of a de-
    fendant based on direct or indirect testimony taken after a
    specific promise of immunity … warrants dismissal of an in-
    dictment.” 
    920 F.2d 421
    , 426 (7th Cir. 1990) (involving use, not
    transactional, immunity). But Cahill involved an alleged
    promise of immunity by a federal prosecutor to the defend-
    ant, so it is distinguishable. Cahill does not suggest that the
    United States Attorney’s Office is bound by a state or judicial
    official’s promise of federal immunity.
    In sum, no evidence suggests the United States Attorney’s
    Office ever considered or approved a federal non-prosecution
    agreement. There is also insufficient evidence to reverse the
    district court’s findings that Johnson was not promised fed-
    eral prosecutorial immunity by either Powell or Jones. Even if
    they had made such promises, Johnson cannot rely on theo-
    ries of inherent or apparent authority because Jones and Pow-
    ell were not agents of the United States Attorney’s Office, and
    federal prosecutors did not make manifestations to Johnson
    that Jones or Powell were authorized to act on their behalf.
    And even if Jones or Powell acted with inherent or apparent
    18                                                   No. 20-3272
    authority, principles of dual sovereignty and the separation
    of powers prevent such unauthorized promises from binding
    the Executive Branch. We thus conclude the district court did
    not err in denying Johnson’s first motion to dismiss based on
    federal immunity.
    B
    Johnson also contends the district court wrongfully de-
    nied his second motion to dismiss the federal indictment as a
    discovery sanction. “When reviewing a court’s decision
    granting or denying a motion to dismiss an indictment be-
    cause of an alleged Brady violation, ‘we look only to see if the
    district court abused its discretion.’” United States v. Barr, 
    960 F.3d 906
    , 916 (7th Cir. 2020) (quoting United States v. Cherry,
    
    920 F.3d 1126
    , 1140 (7th Cir. 2019)). Under this standard, “[w]e
    will reverse the district court only when no reasonable person
    could take the view adopted by the trial court.” United States
    v. Bebris, 
    4 F.4th 551
    , 559 (7th Cir. 2021) (quoting United States
    v. Hamdan, 
    910 F.3d 351
    , 356 (7th Cir. 2018)).
    Under Brady v. Maryland, 
    373 U.S. 83
     (1963), law enforce-
    ment officers “must turn over potentially exculpatory
    evidence when they turn over investigative files to the prose-
    cution.” Jones v. York, 
    34 F.4th 550
    , 558 (7th Cir. 2022) (quoting
    Harris v. Kuba, 
    486 F.3d 1010
    , 1014 (7th Cir. 2007)). “To succeed
    on a Brady claim, a defendant bears the burden of proving that
    the evidence is (1) favorable, (2) suppressed, and (3) material
    to the defense.” United States v. Edwards, 
    34 F.4th 570
    , 587 (7th
    Cir. 2022) (quoting United States v. Walter, 
    870 F.3d 622
    , 629
    (7th Cir. 2017)).
    Johnson’s evidentiary challenge fails under each Brady el-
    ement. To begin, none of the purportedly suppressed
    No. 20-3272                                                             19
    evidence was favorable to Johnson. The emails between Pow-
    ell and Decatur officers, Bohm, Miller, and Judge Baker do not
    mention a federal non-prosecution agreement. In fact, in some
    of her emails, Powell denies any knowledge of a federal im-
    munity deal. These facts support the district court’s finding
    that the belatedly produced emails “work[] against the de-
    fendant, not in his favor.”
    Further, no evidence was “suppressed” within the mean-
    ing of Brady. As Johnson’s counsel recognized at oral argu-
    ment, 8 our case law provides that “[d]elayed disclosure alone
    does not ‘in and of itself constitute a Brady violation.’” Barr,
    960 F.3d at 916 (quoting United States v. O’Hara, 
    301 F.3d 563
    ,
    569 (7th Cir. 2002)). “Instead, the disclosure must come so late
    as to deny the defendant ‘effective use’ of the evidence during
    the relevant proceeding.” 
    Id.
     (quoting United States v. Walton,
    
    217 F.3d 443
    , 451 (7th Cir. 2000)). Johnson had access to the
    first batch of contested emails contained in Powell’s records
    approximately one month before the January 2020 eviden-
    tiary hearing.9 Moreover, Johnson obtained the additional
    twelve pages of emails on March 13. The district court then
    allowed Johnson to supplement his motion for discovery
    sanctions and to file a motion to reconsider the motion to dis-
    miss based on federal immunity. By the time of the April 16
    motion hearing, all the contested emails were available to
    Johnson and had been considered by the district court. John-
    son also argues the Government withheld text messages
    8   Oral Arg. at 15:15.
    9 While Johnson argues the United States Attorney’s Office failed to pro-
    duce its copy of these emails due to data retention procedures, the proba-
    tion office was able to produce its copy of those same emails for Johnson’s
    use.
    20                                                           No. 20-3272
    between Johnson and Jones. But those messages were also in
    Johnson’s possession and the district court considered them
    as part of Johnson’s second motion to dismiss the indictment
    as a discovery sanction. The district court acted well within its
    discretion in finding that Johnson’s access to the emails and
    text messages foreclosed a Brady challenge. 10
    Last, none of the belatedly produced emails were material
    to Johnson’s defense. “[E]vidence is ‘material’ within the
    meaning of Brady when there is a reasonable probability that,
    had the evidence been disclosed, the result of the proceeding
    would have been different.” Turner v. United States, 
    137 S. Ct. 1885
    , 1893 (2017) (alteration in original) (quoting Cone v. Bell,
    
    556 U.S. 449
    , 469–470 (2009)). Because the district court had an
    opportunity to examine the evidence, we need not speculate
    as to whether the emails would have produced a different re-
    sult. The court twice determined there was insufficient evi-
    dence to support Johnson’s federal immunity defense, and we
    cannot say that “no reasonable person could take the view
    adopted by the trial court.” Bebris, 4 F.4th at 559 (quoting
    Hamdan, 910 F.3d at 356).
    *       *       *
    For these reasons, we AFFIRM the district court.
    10 In his reply brief, Johnson argues for the first time on appeal that the
    Government violated Brady by not requesting Jones’s written notes docu-
    menting his interactions with Johnson. But Johnson did not raise this issue
    in his opening brief, and “[a] party that omits from its opening appellate
    brief any argument in support of its position waives or abandons that
    party’s claim on appeal.” White v. United States, 
    8 F.4th 547
    , 552 (7th Cir.
    2021).
