    United States Court of Appeals
    For the Seventh Circuit
    No. 08-1931
    U NITED STATES OF A MERICA,
    Plaintiff-Appellee,
    v.
    A MEN E. JUMAH,
    Defendant-Appellant.
    Appeal from the United States District Court
    for the Northern District of Illinois, Eastern Division.
    No. 1:04-cr-00237-1—John W. Darrah, Judge.
    A RGUED O CTOBER 7, 2009—D ECIDED A PRIL 1, 2010
    Before R IPPLE, K ANNE and SYKES, Circuit Judges.
    R IPPLE, Circuit Judge. Amen E. Jumah was convicted by
    a jury of knowing possession of a listed chemical, knowing,
    or having reasonable cause to believe, that the chemical
    would be used to manufacture a controlled substance
    in violation of 
    21 U.S.C. § 841
    (c)(2). The district court,
    acting without the benefit of the Supreme Court’s subse-
    quent decision in Dixon v. United States, 
    548 U.S. 1
     (2006),
    granted a motion for a new trial on the ground that the
    2                                              No. 08-1931
    jury had been instructed erroneously about the public
    authority defense. We reversed the district court’s grant
    of Mr. Jumah’s motion for new trial and remanded the
    case with instructions to reinstate the jury’s verdict. See
    United States v. Jumah, 
    493 F.3d 868
    , 870 (7th Cir. 2007)
    (“Jumah I”). On remand, the district court considered
    Mr. Jumah’s remaining grounds for a new trial. One of
    those arguments was that the Government had failed to
    comply with its obligations under Brady v. Maryland, 
    373 U.S. 83
     (1963), and Giglio v. United States, 
    405 U.S. 150
    (1972). The district court denied the motion for new trial
    and sentenced Mr. Jumah to 151 months’ imprisonment.
    For the reasons set forth in this opinion, we affirm in
    part and reverse in part the judgment of the district
    court and remand with instructions for re-sentencing.
    I
    BACKGROUND
    A.
    From 2001 to 2002, Mr. Jumah worked periodically as a
    confidential source (“CS”) for the Drug Enforcement
    Administration (“DEA”). He assisted with undercover
    investigations into pseudoephedrine trafficking in
    Chicago and Los Angeles. Mr. Jumah sometimes pro-
    vided information about past pseudoephedrine transac-
    tions. However, Mr. Jumah usually brought to the DEA
    information about a deal that was to occur in the future.
    The DEA asked Mr. Jumah to sign a United States
    Department of Justice confidential source agreement.
    No. 08-1931                                            3
    Under its terms, the DEA authorized him to purchase,
    while undercover and at the direction of the DEA, con-
    trolled substances. The agreement also required
    Mr. Jumah to abide by the instructions of his controlling
    DEA investigators and not to take any independent
    action on behalf of the DEA. Mr. Jumah signed three
    such agreements in 2001 and 2002.
    On May 8, 2002, while Mr. Jumah was deactivated as a
    CS, he contacted a DEA agent and informed him that a
    pseudoephedrine dealer had approached him with an
    offer to buy 300 cases of pseudoephedrine for $150,000.
    DEA agents instructed Mr. Jumah to meet with the
    dealer at a restaurant called Jimmy’s Shishkabob to
    discuss the deal. While the DEA surveilled the meeting,
    Mr. Jumah offered to consummate the deal at another
    location, and the dealer showed that he had the neces-
    sary funds to do so. When Mr. Jumah and the dealer
    left the Jimmy’s Shishkabob restaurant, the DEA stopped
    the car carrying the money and arrested the suspects.
    The DEA paid Mr. Jumah $29,800 for the information
    and assistance he provided. The DEA formally reactivated
    him as a CS several days later.
    In February 2004, Mr. Jumah attempted to sell Ali Qasem
    pseudoephedrine for the purpose of making metham-
    phetamine. Unknown to Mr. Jumah, Qasem was himself
    a CS who worked with the Los Angeles, California
    branch of the DEA. According to Qasem, Mr. Jumah
    initiated the deal. On February 10, 2004, while Qasem
    was en route to Chicago for a meeting with Mr. Jumah,
    Mr. Jumah contacted a DEA agent and inquired about
    4                                                   No. 08-1931
    receiving payment for prior information, unrelated to
    the developing Qasem deal, that Mr. Jumah had pro-
    vided. Mr. Jumah did not inform the agent of the
    pending deal with Qasem.
    Working with Qasem, the DEA listened to telephone
    conversations between Mr. Jumah and Qasem and
    surveilled meetings between them in Illinois from
    February 13 to 16, 2004. During these conversations,
    Mr. Jumah told Qasem that he wanted to conduct the
    pseudoephedrine transaction on a Sunday or Monday
    because the DEA agents would not be working on those
    days. On February 16, the day that Mr. Jumah planned
    to meet Qasem, Mr. Jumah called a DEA agent and
    asked whether the agent was working that day but said
    nothing about the pending deal with Qasem. The DEA
    surveilled additional meetings between Mr. Jumah and
    Qasem in Illinois on March 1 and 2, 2004. On March 2,
    Mr. Jumah called a DEA agent, asked whether the
    agent was working that day and said that he was going
    to meet with an individual, but gave no details
    about the identity of the individual or the purpose of the
    meeting. The DEA agent did not inquire further about
    the matter. Later that day, Mr. Jumah again called the
    DEA agent and left a voicemail message stating, “he
    called me back, and he is going to be in town, in Chicago
    tonight . . . . And I’ll let you know what’s going on . . . if we
    have to set up something for tomorrow or Thursday, uh,
    we’ll see what’s going on.” Tr. at 232, 234, Jan. 26, 2006.
    Mr. Jumah also stated on the voicemail message, “I am
    going to meet him and see and see [sic] what’s going on,
    if he’s, uh, got the cash or not.”

    Mr. Jumah met with Qasem later that day, but Mr. Jumah
    did not inform the DEA agent that the meeting actually
    had occurred. During that meeting, Mr. Jumah gave
    Qasem 1,016 pills containing pseudoephedrine. Qasem
    promptly turned the pseudoephedrine over to the DEA,
    which had been conducting surveillance. The DEA then
    directed Qasem to place a larger order of pseudoephed-
    rine with Mr. Jumah. Mr. Jumah agreed to sell 300 boxes
    of pseudoephedrine to Qasem for $165,000 later that night.
    At approximately 8:00 p.m. on March 2, 2004, Mr. Jumah
    and Qasem met at a casino in Joliet, Illinois, to complete
    the deal. The DEA observed the meeting and watched
    Mr. Jumah leave the casino to pick up the pseudo-
    ephedrine. When Mr. Jumah returned, purportedly with
    the pseudoephedrine, the DEA arrested him and
    searched his vehicle. Inside, the DEA found rock salt that
    was similar in quantity and appearance to the pseudo-
    ephedrine Mr. Jumah had agreed to provide Qasem.
    Upon his arrest, Mr. Jumah waived his Miranda rights
    and made a series of incriminating statements. He first
    stated that one of the DEA agents with whom Mr. Jumah
    had spoken that day had authorized him to conduct the
    Qasem transaction. He further stated that the DEA agent
    had given him the pseudoephedrine. Later, Mr. Jumah
    retracted that statement and said that he had stolen the
    pseudoephedrine from the DEA several months earlier.
    B.
    On March 11, 2004, a federal grand jury returned a one-
    count indictment against Mr. Jumah charging him with
    6                                                  No. 08-1931
    knowingly and intentionally possessing and distrib-
    uting 1,016 tablets of pseudoephedrine, a List I chemical,
    knowing and having reason to believe that the pseudo-
    ephedrine would be used to make methamphetamine,
    in violation of 
    21 U.S.C. § 841
    (c)(2).
    On April 19, 2004, Mr. Jumah filed a motion for discov-
    ery. The Government provided some discovery pursuant
    to Federal Rule of Criminal Procedure 16. Over the next
    year and a half, the trial date was continued several times
    until it was scheduled finally to begin on January 23, 2006.
    On November 8, 2005, Mr. Jumah substituted counsel;
    the district court denied the new counsel’s request for
    an additional continuance.
    Mr. Jumah’s newly substituted counsel then began
    issuing trial subpoenas to DEA agents.1 On January 9,
    1
    Specifically, on December 8, 2005, Mr. Jumah issued two trial
    subpoenas to the DEA Keeper of Records. The first subpoena
    requested: (1) all names of DEA agents who had contact
    with Mr. Jumah; (2) the dates of those contacts; and (3) items
    memorializing those contacts. The second subpoena requested:
    (1) all documents related to Mr. Jumah; (2) all documents
    related to Qasem becoming a CS for the DEA; (3) payments
    made to Qasem by the DEA; and (4) Qasem’s criminal history.
    On December 27, 2005, Mr. Jumah issued four trial subpoenas
    to California DEA agents Bradley Clemmer, Ted Salamy, Efren
    Lapuz and George Newland. The subpoena to Bradley Clemmer
    sought: (1) the substance of Agent Clemmer’s testimony at trial;
    and (2) all documents memorializing his contacts with
    Mr. Jumah, including the dates, times, duration, and nature
    (continued...)
    No. 08-1931                                                    7
    2006, Mr. Jumah’s counsel also filed a motion for im-
    mediate disclosure of favorable evidence, requesting that
    the Government turn over all Brady and Giglio evidence.
    On January 11, 2006, the Government filed a motion to
    quash the subpoenas on the ground that the requested
    documents were not required to be disclosed by the
    1
    (...continued)
    of the contacts, as well as Mr. Jumah’s duties. The subpoena to
    Ted Salamy sought: (1) the substance of Agent Salamy’s testi-
    mony at trial; (2) all documents memorializing his contacts
    with Qasem; (3) any statements made by Qasem about his
    criminal past; (4) all documents memorializing when Qasem
    became a CS for the DEA; (5) all agreements with Qasem and
    confidential-source-establishment documents; and (6) payments
    to Qasem. The subpoena to Efren Lapuz sought: (1) the sub-
    stance of Agent Lapuz’s testimony at trial; (2) all documents
    memorializing his contacts with Qasem; and (3) all documents
    relating to payments made to Qasem by DEA in the investiga-
    tion of Mr. Jumah. The subpoena to George Newland sought:
    (1) all documents memorializing his contacts with Qasem
    relating to the Jumah investigation; and (2) all payments
    made to Qasem by DEA in the Jumah investigation.
    On January 6, 2006, Mr. Jumah issued another trial subpoena
    to FBI Agent John Diwik. The subpoena to Agent Diwik sought
    Agent Diwik’s testimony at trial regarding: (1) the first date
    Mr. Jumah acted as a CS for the FBI; (2) the number of investiga-
    tions Mr. Jumah worked on; (3) how much Mr. Jumah was
    paid for his work; (4) the method, manner and times Agent
    Diwik communicated with Mr. Jumah; and (5) a list of agencies
    that Mr. Jumah worked for at the direction of or on the recom-
    mendation of Agent Diwik.
    8                                               No. 08-1931
    discovery rules, were irrelevant to the case or lacked
    evidentiary value. R.68. The Government also stated that
    it had met its obligations under Brady but that its review
    for the Giglio material was still ongoing. Specifically, the
    Government stated,
    Jumah was a DEA [CS] in Chicago and Los An-
    geles, California and an FBI [CS] in Chicago, and
    Qasem was a [CS] in Riverside, California; San
    Diego, California; and Chicago, Illinois. The gov-
    ernment has produced all Giglio materials con-
    tained in Jumah’s and Qasem’s DEA [CS] files in
    Chicago and will produce by January 12, 2006 all
    Giglio materials contained in Jumah’s FBI [CS] file.
    The [CS] files in Los Angeles, Riverside, and San
    Diego, however, have not been fully reviewed.
    These files cannot be sent to Chicago and, there-
    fore, must be reviewed by attorneys in those
    cities. The government is working diligently to
    get this review completed, but it has not at this
    time been done.
    R.68 at 7. The Government also requested, with
    Mr. Jumah’s consent, that trial be continued to allow
    completion of the Government’s Giglio search.
    The next day, on January 12, 2006, the district court held
    a hearing to consider these issues. The district court
    denied the requested continuance. The district court stated,
    “I’m amenable to anything that needs my cooperation
    to see that this favorable evidence, if in fact that’s what
    it is, is produced, but we are going to trial on this case
    on January 23rd.” Tr. at 4, Jan. 12, 2006.
    No. 08-1931                                                9
    At the hearing, the Government assured the district
    court that it had produced all materials it was obligated
    to produce pursuant to Rule 16, 
    18 U.S.C. § 3500
     and
    Brady. See Tr. at 7-8, Jan. 12, 2006. However, the Govern-
    ment reiterated that it needed more time to complete
    its Giglio search and production. Specifically, it stated,
    The [CS] files in Chicago, both Mr. Juma’s [sic] file
    with the FBI and Mr. Jumah [sic] and Mr. Qasem’s
    file with the DEA have been reviewed and all
    Giglio materials that were within those files have
    been turned over to the defense. With regard to the
    files in California, a DEA attorney in California is
    reviewing, is going to each of those cities and is
    reviewing those files. That is currently being
    undertaken.
    
    Id. at 8-9
    . The district court held that the Government had
    complied with its Brady obligations and directed the
    Government to complete its search for any Giglio respon-
    sive documents in its California offices by the following
    Tuesday. 
    Id. at 12
    .
    The district court then took up the Government’s motion
    to quash the subpoenas. Mr. Jumah maintained that he
    was entitled to the entire file that the DEA kept con-
    cerning him and Qasem, including all records of all
    statements made by Mr. Jumah and Qasem related to
    prior investigations in which they had participated.
    Mr. Jumah maintained that those materials would be
    probative on the issue of his state of mind during the
    February 2004 incident and his course of conduct as a
    DEA CS. Mr. Jumah also suggested that he needed to
    10                                             No. 08-1931
    review the files to disprove the DEA’s position that it
    never had provided samples of pseudoephedrine to
    Mr. Jumah for his work in any investigation. The Gov-
    ernment opposed the request and maintained that
    Mr. Jumah was not entitled to materials beyond those that
    qualified as Rule 16, § 3500, Brady or Giglio materials
    and reiterated that this material already had been pro-
    duced for the most part. The Government also stated
    that no documents existed concerning the distribution
    of pseudoephedrine samples to Mr. Jumah because the
    DEA in Chicago had confirmed that such distribution
    never had occurred.
    The district court granted the motion to quash all the
    trial subpoenas, except the subpoena of Agent DeWitt
    because Mr. Jumah intended to call him at trial. Tr. at 23-
    24, Jan. 12, 2006. As to the other subpoenas, the district
    court stated that Mr. Jumah was merely seeking materials
    “derivative from Brady and Giglio” materials that the
    Government already had produced or was in the
    process of identifying and producing. Id. at 11. The
    district court stated that Mr. Jumah was not entitled to
    “every piece of minutia in the conduct of government
    agents and people working for them in the course of an
    investigation.” Id. at 19-20. However, the district court
    directed that the Government contact anyone Mr. Jumah
    had worked for as an informant, including the Chicago
    and California DEA offices, to inquire, again, about the
    existence of any documents showing that the DEA had
    provided Mr. Jumah with pseudoephedrine samples. Id.
    at 17-18. Finally, the district court noted that Mr. Jumah
    No. 08-1931                                                11
    had to “rely on the bonafides of the government” with
    respect to its representations about the existence of any
    remaining Brady and Giglio material. Id. at 16-17.
    On January 17, 2006, the Government apparently sent
    Mr. Jumah a letter confirming that it had completed its
    search for Giglio materials in the California DEA offices
    and found none. See Appellee’s Br. 17. That letter was not
    made part of the record.
    At a pre-trial conference on January 18, 2006, the Gov-
    ernment again brought up the subpoenas issue and the
    district court foreclosed further discussion of the matter.
    The following colloquy occurred:
    [THE GOVERNMENT]: As the court pointed out at
    the last hearing, with regard to the defense’s
    subpoenas, the information that was requested in
    those subpoenas, as the government understood
    it from the court’s ruling, was determined to be
    irrelevant because in fact whether Mr. Jumah—
    THE COURT: Let me say this, that the basis of my
    ruling is what I said in the courtroom last week,
    and both of you have taken a little bit of liberty
    in characterizing to your advantage what you
    believe would be, I think, a little extrapolation of
    what I said. So what I said I said, and that’s on
    the record last week, and those are the reasons
    for my ruling.
    See Tr. at 14, Jan. 18, 2006. Later in that hearing, the Gov-
    ernment reminded the district court that it had directed
    the Government to inquire specifically into whether any
    12                                              No. 08-1931
    federal agency had ever provided Mr. Jumah with
    pseudoephedrine samples. The Government represented
    that its review of Mr. Jumah’s files in Chicago and
    Los Angeles produced no documents showing that
    Mr. Jumah ever had been provided with pseudoephed-
    rine samples. Id. at 20.
    On or around January 20, 2006, during an interview with
    Qasem, the Government learned for the first time that
    Qasem had conducted two pseudoephedrine deals with
    Mr. Jumah in 2001. The Government considered that
    information to be Giglio material and disclosed it to
    Mr. Jumah by fax on January 21, 2006. See Appellee’s Br. 17;
    R.107 at 13. Also, on January 20, 2006, the Government
    filed a motion in limine to permit the admission at trial of
    evidence and arguments concerning those drug deals—i.e.,
    Jumah’s prior uncharged criminal acts—as inextricably
    intertwined with the charged offense. R.87. The district
    court conditionally precluded the evidence without
    prejudice to renewal of the motion at trial. R.136-2; see
    also Appellee’s Br. 18.
    Trial was held, beginning one day early, on January 25,
    2006. At trial, the Government introduced testimony
    from Chicago DEA agents that Mr. Jumah was not an
    active CS at the time of the deal with Qasem and that
    Mr. Jumah had acted independently and without
    authority from the DEA to possess and sell pseudo-
    ephedrine. DEA agents testified about prior sting opera-
    tions in which Mr. Jumah had participated, including the
    Jimmy’s Shishkabob incident. The DEA agents explained
    that under no circumstances would Mr. Jumah have been
    No. 08-1931                                                       13
    allowed to sell pseudoephedrine without the DEA’s
    knowledge and then benefit from information provided
    therefrom. The DEA agents also described the events that
    occurred on and leading up to March 2, 2004. Qasem
    testified as a Government witness about the March 2004
    events and stated that he had known Mr. Jumah for
    approximately fourteen years. See Trial Tr. at 312, Jan. 26,
    2006. On cross-examination of Qasem, Mr. Jumah’s
    counsel did not explore their prior relationship in any
    detail.2
    Mr. Jumah’s defense was that he reasonably believed
    he had authority to enter into the pseudoephedrine deal
    with Qasem. Mr. Jumah read stipulations into evidence
    showing that he was employed as a DEA CS from time-to-
    time, that Mr. Jumah made several phone calls to the
    DEA agents on and around March 1-2, 2004, and that
    Mr. Jumah knew that Qasem was traveling to Illinois in
    2
    On cross-examination of Qasem, defense counsel began
    asking about Qasem’s prior relationship with Mr. Jumah and
    how long the two men had known each other. Trial Tr. at 414,
    Jan. 27, 2006. The attorney for the Government objected and
    stated, “I just want to notify the court that if [defense counsel is]
    going to go into the fact that [Qasem] doesn’t trust [Mr. Jumah]
    and why he doesn’t trust [Mr. Jumah], that’s what I intend
    on asking on cross examination [sic], and I believe she’s
    opened the door at this point.” Id. at 415. The district court
    overruled the objection. Id. However, defense counsel moved
    on to another line of questioning and did not ask Qasem
    additional questions about his prior relationship with
    Mr. Jumah.
    14                                             No. 08-1931
    February 2004. Mr. Jumah did not testify at trial. Nor
    did he introduce evidence showing that the Govern-
    ment provided him with pseudoephedrine samples.
    Neither party offered evidence showing that Mr. Jumah
    and Qasem previously had conducted drug deals with
    each other.
    On January 27, 2006, the jury convicted Mr. Jumah on
    the one count of distributing 1,016 pills containing
    pseudoephedrine. As we have noted earlier, the
    district court granted a new trial because it believed
    that the jury had been instructed erroneously on the
    public authority defense. We reversed that ruling, see
    Jumah I, 
    493 F.3d at 878-79
    , and, on remand, the
    district court proceeded to consider Mr. Jumah’s other
    proffered grounds for a new trial. Among them was the
    contention that the Government had failed to disclose
    documents pursuant to its obligations under Brady v.
    Maryland, 
    373 U.S. 83
    , 87 (1963), and Giglio v. United
    States, 
    405 U.S. 150
    , 153 (1972). See R.101. On January 29,
    2008, the district court denied the motion, ruling that
    Mr. Jumah failed to show that the Government had
    withheld any evidence that qualified as Brady or Giglio
    material. See R.178 at 4.
    On April 9, 2008, the district court sentenced Mr. Jumah
    to 151 months’ imprisonment. See Tr. at 23, Apr. 9, 2008;
    R.183. The district court calculated the Guidelines ac-
    cording to the gross weight of the pseudoephedrine
    pills, instead of the weight of the pure drugs contained
    therein. No party objected to the district court’s calcula-
    tions, which were in accordance with the Presentence
    No. 08-1931                                                15
    Investigation Report (“PSR”) calculations. On April 16,
    2008, Mr. Jumah timely appealed.

    DISCUSSION
    A.
    We first consider Mr. Jumah’s claim that his right to
    due process of law as guaranteed by the Fifth Amendment
    was violated by the Government’s withholding of evi-
    dence. We review a district court’s decision that evidence
    need not be produced under Brady or Giglio for an abuse
    of discretion. See United States v. Olofson, 
    563 F.3d 652
    , 661
    (7th Cir. 2009).
    Mr. Jumah primarily contends that the Government
    conducted an inadequate search for Brady and Giglio
    material in its possession, both in Illinois and in Cali-
    fornia. Mr. Jumah maintains that he was entitled to
    receive his complete CS file from the DEA and FBI. He
    also contends that he was entitled to receive Qasem’s
    complete CS file and the DEA’s debriefings of Qasem
    in connection with the investigation of Mr. Jumah. Ap-
    pellant’s Br. 22, 29. Mr. Jumah believes that the CS files
    would have shown that the DEA provided him with
    pseudoephedrine samples in the past. He also states that
    the CS files would have supported his theory that, even
    when he was deactivated, he routinely would obtain
    information regarding possible criminal conduct and
    bring it to the attention of the DEA agents “after it ripened
    into a possible sting.” See id. at 22. He believes that the
    CS files would show that, prior to 2004, Mr. Jumah had
    16                                                  No. 08-1931
    participated in investigations into Qasem’s narcotics
    dealings and that “Qasem was a long-standing target of
    Jumah’s work as a CS.” Id. at 22-23, 29.3
    Mr. Jumah contends that the Government cannot avoid
    its duties by asserting that relevant materials are not in
    its possession. Id. at 27 (citing Crivens v. Roth, 
    172 F.3d 991
    ,
    996 (7th Cir. 1999)). He further contends that “[w]here
    evidence is in the exclusive control of the government or
    has been destroyed by the government, a defendant
    may establish that the government suppressed excul-
    patory evidence without specifically identifying the
    allegedly suppressed evidence, if the defendant makes
    some showing that evidence was suppressed.” 
    Id.
     at 28
    (citing United States v. Driver, 
    798 F.2d 248
    , 251 n.1 (7th
    Cir. 1986)). Mr. Jumah notes that in Pennsylvania v.
    Ritchie, 
    480 U.S. 39
    , 58 n.15 (1987), “the Supreme Court
    held that a defendant, charged with the rape and incest
    of his daughter, was entitled to have the state’s Children
    and Youth Services file on his daughter reviewed by the
    trial court to determine whether it contained Brady infor-
    3
    Mr. Jumah also intimates that the district court committed
    reversible error by denying the Government’s motion for a
    continuance. See Appellant’s Br. 27. However this argument
    is not pursued seriously in Mr. Jumah’s briefing; thus, we
    treat it as waived. Also, at oral arguments, Mr. Jumah main-
    tained that the district court erred by limiting the scope of the
    Government’s search of its California files. We consider that
    argument to be part and parcel of Mr. Jumah’s argument that his
    right to due process of law was violated by the Government’s
    failure to turn over all Brady and Giglio responsive materials.
    No. 08-1931                                               17
    mation.” Appellant’s Br. 30 (describing Ritchie). Finally,
    Mr. Jumah contends that he particularly deserved to
    receive Qasem’s file and the DEA’s debriefings of Qasem
    because Qasem provided unverified testimony about
    what was said in the conversations between Mr. Jumah
    and Qasem. Id. at 32 (quoting United States v. Wong, 
    78 F.3d 73
    , 79 (2d Cir. 1996)).
    The Government reiterates that it completed its review
    of Mr. Jumah’s and Qasem’s CS files, including the Califor-
    nia files, by January 17, 2006, and found no Brady or Giglio
    material other than what it turned over. Appellee’s Br.
    19. The Government maintains that Mr. Jumah now
    speculates that additional responsive documents exist in
    the CS files. Although the Government denies that such
    documents exist, it further maintains that Mr. Jumah “is
    not entitled to scour government files in the hopes of
    finding Brady/Giglio material.” 
    Id.
     (citing United States v.
    Phillips, 
    854 F.2d 273
    , 277 (7th Cir. 1988)). The Govern-
    ment concedes that an in camera inspection of Gov-
    ernment files is sometimes appropriate, but notes that
    Mr. Jumah never asked for an in camera inspection of the
    records in this case. Id. at 20-21. Finally, in response to
    Mr. Jumah’s argument with respect to specific documents,
    the Government asserts that: (1) it never gave pseudo-
    ephedrine samples to Mr. Jumah and did not withhold
    any documents showing otherwise, id. at 21, 26; (2) its files
    do not contain any documents showing that Mr. Jumah
    and Qasem had engaged in two previous pseudo-
    ephedrine deals, particularly because the Government
    learned of those deals from Qasem only on the eve of trial
    and alerted Mr. Jumah accordingly, id. at 23; and (3) it
    18                                               No. 08-1931
    “gave the defendant all documents related to Qasem’s
    participation in the investigation of the defendant,”
    including documents titled “debriefings” and those
    titled “case status reports,” id. at 24.
    In Brady, 
    373 U.S. at 87
    , the Supreme Court held that “the
    suppression by the prosecution of evidence favorable to
    an accused upon request violates due process of law
    where the evidence is material either to guilt or to punish-
    ment irrespective of the good faith or bad faith of the
    prosecution.” The Supreme Court further held in Giglio,
    
    405 U.S. at 153
    , that any material evidence which
    might undermine the reliability of a government wit-
    ness must be turned over to a defendant. In other words,
    a new trial is required if the evidence at issue is (1) favor-
    able, (2) suppressed and (3) material to the defense.
    See United States v. Wilson, 
    237 F.3d 827
    , 832 (7th Cir.
    2001). “[E]vidence is material only if there is a reason-
    able probability that, had the evidence been disclosed to
    the defense, the result of the proceedings would have
    been different.” United States v. Bagley, 
    473 U.S. 667
    , 682
    (1985) (Blackmun, J., concurring); Kyles v. Whitley, 
    514 U.S. 419
    , 434 (1995) (discussing the Bagley standard). “Reason-
    able probability” does not mean something greater than
    50% but rather “whether in . . . [the] absence [of the
    evidence, the defendant] received a fair trial, understood
    as a trial resulting in a verdict worthy of confidence.”
    Kyles, 
    514 U.S. at 434
    .
    The defendant has the burden to establish that a Brady
    or Giglio violation occurred. See Wilson, 
    237 F.3d at 832
    .
    However, prosecutors “have an affirmative duty to dis-
    No. 08-1931                                                   19
    close such evidence and a duty to ‘learn of any favorable
    evidence known to the others acting on the govern-
    ment’s behalf in the case, including the police.’ ” Crivens v.
    Roth, 
    172 F.3d 991
    , 996 (7th Cir. 1999) (quoting Kyles,
    
    514 U.S. at 432
    ). Thus, while “[p]rosecutors may not
    simply claim ignorance of Brady material,” id. at 996, a
    defendant cannot demand a new trial based on “mere
    speculation” or “unsupported assertion[s] that the gov-
    ernment suppressed evidence,” United States v. Driver,
    
    798 F.2d 248
    , 251 (7th Cir. 1986).
    In light of this standard, we cannot agree with Mr. Jumah
    that the Government conducted an inadequate search
    for responsive Brady or Giglio material. As an initial
    matter, Mr. Jumah was not entitled to receive his entire
    CS file or government files concerning Qasem. See United
    States v. Philips, 
    854 F.2d 273
    , 278 (7th Cir. 1988) (“[W]e
    hasten to point out that Brady does not grant criminal
    defendants unfettered access to government files.”).4
    Rather, he was entitled to receive any documents materi-
    ally favorable to him or which might undermine the
    reliability of witnesses.
    The Government conducted a sufficient search of its
    files for documents falling into that category. As of the pre-
    trial hearing on January 12, 2006, the Government repre-
    sented that it had produced all Brady material in its
    possession. The district court accepted the Government’s
    4
    At least with respect to documents concerning Qasem’s
    participation in the investigation into Mr. Jumah, the Govern-
    ment claims that it actually produced its entire file. See Appel-
    lee’s Br. 24-25.
    20                                                 No. 08-1931
    representation and reminded Mr. Jumah that, without
    allegations of specific pieces of evidence that had been
    withheld, he had to rely on “the bonafides of the govern-
    ment.” See Tr. at 16-17, Jan. 12, 2006. At that hearing,
    however, the Government indicated that it still needed
    to complete a review of its California files for Giglio
    material, and the district court urged the Government
    to expedite the search.
    Then, at the January 18 conference, the Government
    assured the district court that it had completed its review
    of the California files and had found no responsive docu-
    ments. The record is clear that the Government com-
    pleted its search of the California files. The Government
    referred to its search of the California files for documents
    specifically related to past instances of distribution of
    pseudoephedrine to Mr. Jumah and informed the
    district court that it had found none. Moreover, the
    record cannot be fairly read as reflecting that the Gov-
    ernment, in searching for this information in its files, was
    oblivious to its broader duty to disclose any other excul-
    patory or impeachment material. Indeed, throughout
    its filings before the district court and this court, the
    Government has maintained that it conducted a thorough
    search of all its files in all offices for Brady and Giglio
    material and withheld nothing.5
    5
    We have no need to consider the Government’s contention,
    made in its brief apparently for the first time, that it sent
    Mr. Jumah a letter confirming that it had completed its search
    for Giglio materials in the California DEA files on January 17,
    (continued...)
    No. 08-1931                                                      21
    If Mr. Jumah believed that he needed access to his and
    Qasem’s entire DEA files, he could have requested that
    the district court undertake a review in camera of the
    Government’s files. Cf. Ritchie, 
    480 U.S. at
    58 n.15 (ex-
    plaining that to obtain an in camera inspection from the
    district court, the defendant must “at least make some
    plausible showing” that documents in the government’s
    possession contain information “both material and favor-
    able to his defense” (internal quotation marks omitted)).6

    (...continued)
    2004. See Appellee’s Br. 17. This letter is not in the record, and
    we base our decision only on the hearing and conference
    transcripts available to us.
    6
    In Pennsylvania v. Ritchie, 
    480 U.S. 39
    , 58 (1987), the Supreme
    Court outlined a general standard for determining when to
    grant an in camera inspection of governmental documents for
    Brady/Giglio responsive material. The Court explained that a
    defendant “may not require the trial court to search through
    [a governmental] file without first establishing a basis for his
    claim that it contains material evidence.” 
    Id.
     at 58 n.15; see also
    
    id. at 57
     (“ ’[E]vidence is material only if there is a reasonable
    probability that, had the evidence been disclosed to the
    defense, the result of the proceeding would have been differ-
    ent.’ ” (quoting United States v. Bagley, 
    473 U.S. 667
    , 682 (1985)).
    Whether the defendant establishes such a basis may depend
    on “the degree of specificity of [the defendant’s] request.” 
    Id.
    at 58 n.15. A defendant must “at least make some plausible
    showing” that the withheld material is “both material and
    favorable to his defense.” 
    Id.
     (internal quotation marks omitted).
    “[M]ere speculation that a government file might contain
    Brady material is not sufficient.” United States v. Bland, 517 F.3d
    (continued...)
    22                                                    No. 08-1931
    Such a review is the accepted procedure for resolving
    legitimate doubt about the existence of undisclosed
    material and one that balances the defendant’s important
    need for access to potentially relevant material with
    the Government’s valid interest in protecting confiden-
    tial files and the integrity of pending investigations. See
    Phillips, 
    854 F.2d at 278
    .7 Mr. Jumah did not make such
    a request of the district court and appears to have
    dropped the matter after the January 18, 2004 conference.
    The district court certainly was not obligated to conduct
    an in camera review sua sponte.
    Mr. Jumah’s theory that the Government withheld
    Brady and Giglio material is rendered all the more specula-
    tive by the evidence before us in the record. There was
    no evidence that the DEA ever provided Mr. Jumah
    with pseudoephedrine samples in the past. Mr. Jumah
    had ample opportunity to cross-examine the DEA agents
    who testified as Government witnesses about this
    matter and was unable to elicit any testimony supportive
    6
    (...continued)
    930, 935 (7th Cir. 2008). Courts have applied this “plausible
    showing” standard in cases where the Government opposed a
    defendant’s request for an in camera review. See, e.g., Davis v.
    Litscher, 
    290 F.3d 943
    , 947-48 (7th Cir. 2002); United States v.
    Runyan, 
    290 F.3d 223
    , 245 (5th Cir. 2002); Riley v. Taylor, 
    277 F.3d 261
    , 301 (3d Cir. 2001); Love v. Johnson, 
    57 F.3d 1305
    , 1313-15
    (4th Cir. 1995).
    7
    Of course, the district court is under no independent duty
    to review government files for potential Brady material. See
    Bland, 517 F.3d at 935.
    No. 08-1931                                                23
    of his position. Nor was Mr. Jumah able to establish a
    pattern of obtaining information regarding criminal
    conduct and bringing it to DEA agents only after it
    “ripened into a possible sting.” See Appellant’s Br. 22.
    Indeed, the record demonstrates that the DEA did not
    permit Mr. Jumah to engage in actual pseudoephedrine
    deals without its close supervision and direction. Finally,
    we have no reason to believe that the Government main-
    tained records about Qasem’s past that would have
    been helpful to Mr. Jumah. Notably, Mr. Jumah had an
    opportunity to cross-examine Qasem about their prior
    relationship and failed to establish that they had had a
    pattern of drug dealings in the past. See supra note 2.
    We have stated that, when evidence is in the exclusive
    control of the Government or has been destroyed by
    the Government, a defendant may establish that the
    Government suppressed exculpatory evidence without
    specifically identifying the allegedly suppressed evidence.
    See Driver, 
    798 F.2d at
    251 n.1. On the other hand, we
    have also stressed that unsupported assertions that the
    Government has suppressed evidence are insufficient to
    make out a Brady or Giglio violation. 
    Id. at 251
    ; see also
    United States v. Andrus, 
    775 F.2d 825
    , 843 (7th Cir. 1985) (“A
    due process standard which is satisfied by mere specula-
    tion would convert Brady into a discovery device and
    impose an undue burden upon the district court.” (internal
    quotation marks omitted)). We must conclude, on the
    record before us, that Mr. Jumah’s assertions remain
    unsupported. His failure to ask for an in camera inspec-
    tion of the Government’s records further counsels against
    24                                              No. 08-1931
    any relief from this court. The district court committed
    no error.
    B.
    Mr. Jumah also contends that the district court erred
    in the imposition of the sentence. We review the district
    court’s application of the Sentencing Guidelines de novo
    and its factual findings for clear error. See United States
    v. Turner, 
    400 F.3d 491
    , 500 (7th Cir. 2005); see also
    United States v. Garcia, 
    413 F.3d 201
    , 221-24 (2d Cir. 2005)
    (explaining the standard of review and why the clear
    error standard of review for factual findings applies even
    though the ultimate issue is reasonableness). When no
    objection to sentencing guidelines calculations is made
    at trial, we review those calculations for plain error.
    See United States v. Jaimes-Jaimes, 
    406 F.3d 845
    , 847-49
    (7th Cir. 2005). Under plain-error review, the defendant
    must show that (1) there was error, (2) it was plain, (3) it
    affected his substantial rights and (4) the court should
    exercise its discretion to correct the error because it seri-
    ously affected the fairness, integrity or public reputation
    of the judicial proceedings. See United States v. Olano, 
    507 U.S. 725
    , 732-35 (1993); Jaimes-Jaimes, 
    406 F.3d at 847-49
    .
    1.
    At trial, the parties stipulated that Mr. Jumah had
    distributed approximately 1009.4 tablets of pseudo-
    ephedrine; the parties also accepted a chemist’s report
    weighing the tablets at approximately 247.9 grams. Trial
    No. 08-1931                                                  25
    Tr. at 170-71, Jan. 25, 2006.8 In preparation for sentencing,
    the probation officer prepared a PSR that calculated
    Mr. Jumah’s base offense level as 32. This calculation
    was pursuant to U.S.S.G. § 2D1.11(d)(6) and based on the
    assumption that the total weight of the pseudoephedrine
    pills was 253.9 grams.9 However, the PSR did not con-
    sider the fact that the chemist’s report also calculated
    the total weight of pure drug within the pills to be 60.47
    grams. See Gov’t App. at 25.
    The sentencing hearing was held on April 9, 2008. On
    two occasions, Mr. Jumah’s counsel stated that he did not
    object to the calculations in the PSR. See Tr. at 3, 7, Apr. 9,
    2008. Hearing no objection, the district court accepted
    the calculations and findings of the PSR. Id. at 7-8. The
    district court determined that Mr. Jumah’s base offense
    level was 32 and that the two-level obstruction of justice
    enhancement applied, bringing Mr. Jumah’s base offense
    level up to 34. Based on that level and Mr. Jumah’s crimi-
    nal history category of I, the district court determined
    that Mr. Jumah’s Guideline range was 151 to 188 months’
    imprisonment. Id.
    8
    The parties now agree that the stipulation was slightly
    incorrect. Based on the chemist’s report forming the basis of
    the stipulation, the total gross weight of the tablets was 253.9
    grams. See Gov’t App. at 25. Despite this inaccuracy in the
    stipulation, no additional factual hearing is needed since
    this unobjected to, documentary evidence is in the record.
    9
    The PSR utilized the 2007 version of the Guidelines.

    In his sentencing memorandum and at the sentencing
    hearing Mr. Jumah urged the district court to impose
    a lower sentence for several reasons. Mr. Jumah asserted
    that, because of his history of cooperation with the Gov-
    ernment, he would suffer the risk of physical harm in
    prison. He urged the district court to depart from the
    Guidelines because, after serving his prison term, he
    likely would be deported to Israel; he believed that he
    would face a particular physical danger there because of
    the presence of individuals whom he had helped prose-
    cute. He also asked the district court to consider that he
    would not be permitted to serve the last ten percent of
    his sentence in community confinement due to his immi-
    grant status. He stressed his years of cooperation with
    the federal government and highlighted a letter from a
    DEA agent to the district court stating that Mr. Jumah
    was hardworking and “a man of his word,” who had
    earned the agent’s trust. R.181, Ex. 1. Finally, Mr. Jumah
    informed the district court that, during his time in prison,
    he had taken educational courses offered by the prison.
    The Government disputed the relevance or factual accu-
    racy of some of those characteristics.
    After calculating the Guidelines sentence, the district
    court stated that it had considered the nature of the
    offense and the fact that Mr. Jumah’s conduct “resulted or
    could have resulted in the injury to other people that
    were going to use these drugs that [Mr. Jumah was]
    attempting to distribute.” Tr. at 21, Apr. 9, 2008. The
    district court then stated that it had considered “the need

    Mr. Jumah’s] history and characteristics.” Id. Taking those
    considerations into account, the district court stated that
    “a sentence within the sentencing guideline range is
    necessary.” Id. The district court then considered some
    of the unique characteristics raised by Mr. Jumah.
    Mr. Jumah’s assertion that he would suffer the risk of
    physical harm in prison was not supported by “any
    reliable information . . . [and was] contrary to [his]
    recent history since coming to the attention of the
    Court.” Id. Mr. Jumah’s assertion that he would be de-
    ported to a place that presented a physical danger to
    him was not a proper consideration in fashioning a sen-
    tence and, in any event, was a problem of Mr. Jumah’s
    own making because he had violated immigration laws.
    Finally, the district court stated that it thought that “the
    fact that [Mr. Jumah] will not be permitted to serve the
    last ten percent of [his] sentence with some kind of com-
    munity confinement . . . supports a sentence at the low
    end of the guidelines.” Id. at 22. Therefore, the district
    court sentenced Mr. Jumah to 151 months’ imprisonment.
    Id. at 22-23.
    On April 21, 2008, Mr. Jumah filed a pro se Federal Rule
    of Criminal Procedure 35 motion for correction of a sen-
    tence resulting from an arithmetical, technical, or other
    clear error. R.190.10 On August 26, 2008, the district court

    Initially, the Rule 35 motion did not specifically reference the
    difference between the weight of the total tablets and the
    weight of the pure drugs within them. See R.190. However,

    dismissed the motion for lack of subject matter jurisdic-
    tion. R.216.
    2.
    Mr. Jumah now submits that the district court com-
    mitted two reversible errors during sentencing. First,
    Mr. Jumah contends that the district court relied on the
    wrong weight of the pseudoephedrine when calculating
    his base offense level; instead of using the amount of
    total weight of the pseudoephedrine tablets, the district
    court should have used the weight of pure drug within
    the tablets pursuant to U.S.S.G. § 2D1.11, note (C). See
    United States v. Goodhue, 
    486 F.3d 52
    , 59 (1st Cir. 2007).
    Mr. Jumah contends that he objected to the district
    court’s calculations in his Rule 35 motion. Second,
    Mr. Jumah contends that the district court gave no mean-
    ingful consideration to the § 3553(a) factors, including
    those specifically raised by Mr. Jumah in his sentencing
    memorandum and at his sentencing hearing.
    The Government contends that Mr. Jumah’s Rule 35
    motion was improper and untimely, and thus his first
    10
    (...continued)
    Mr. Jumah, through appointed counsel, supplemented the
    motion on August 11, 2008, and thereby disputed the district
    court’s calculation of the Guidelines based on the weight of
    the pseudoephedrine tablets. See R.212. In that supplemental
    memorandum, Mr. Jumah also stated that he had mailed
    his original Rule 35 motion “within the prescribed time limit.”
    Id. at 1 n.2.
    No. 08-1931                                             29
    objection was not preserved. Nevertheless, the Govern-
    ment admits that the district court committed plain
    error by basing its Guidelines calculations on the gross
    weight of the tablets, instead of the weight of the drugs
    within them. The Government opposes Mr. Jumah’s
    second contention and maintains that the district court
    adequately considered the § 3553(a) factors, as well as
    the unique factors Mr. Jumah raised in his sentencing
    memorandum and at the sentencing hearing.
    a.
    We begin by noting that both parties now agree that
    it was plain error for the district court to use the gross
    weight of the pseudoephedrine tablets in calculating
    Mr. Jumah’s sentence. Compare Appellee’s Br. 30, with
    Appellant’s Reply Br. 2. We agree. The Guidelines
    require district courts to calculate the base offense level
    using the weight of the recovered pseudoephedrine
    contained in the tablets, not the weight of the entire
    tablet. See U.S.S.G. § 2D1.11, note (C). Thus, there was
    plain error in the calculations. The error affected
    Mr. Jumah’s substantial rights because, had the district
    court calculated the base offense level using the weight of
    the pure drugs, Mr. Jumah would have been entitled to
    the base offense level of 28 and, with the addition of
    the two-level enhancement, a total offense level of 30.
    With a total offense level of 30 and criminal history cate-
    gory of I, Mr. Jumah’s Guideline range should have been
    97 to 121 months’ imprisonment, rather than the 151 to
    188 months’ imprisonment range calculated by the
    30                                              No. 08-1931
    district court. We shall exercise our discretion and
    remand this case to the district court for resentencing
    because, as both parties agree, the error seriously
    affected the fairness and integrity of the judicial pro-
    ceedings before the district court.
    b.
    Our examination of the record convinces us that the
    district court did not err otherwise with respect to its
    calculations or its statement of reasons. The district court
    explicitly stated that it had considered the § 3553(a)
    factors during the sentencing hearing. It also considered
    Mr. Jumah’s history and personal characteristics. See Tr.
    at 21, Apr. 9, 2008. Although the district court did not
    state specifically that it had considered Mr. Jumah’s
    history of cooperation with federal authorities, the DEA
    agent’s letter or Mr. Jumah’s completion of educational
    courses while in prison, we believe the record sufficiently
    indicates that the district court took these factors into
    consideration in fashioning its sentence. See United States
    v. Martinez, 
    520 F.3d 749
    , 752-53 (7th Cir. 2008) (holding
    that the district court need not make factual findings as
    to each of the sentencing factors but the record must
    show that the court considered them); United States v.
    Dale, 
    498 F.3d 604
    , 611-12 (7th Cir. 2007) (same). Indeed,
    its consideration of the pertinent factors appears compre-
    hensive and thoughtful. In light of the district court’s
    explicit consideration of several of Mr. Jumah’s charac-
    teristics and its statement that it had considered
    Mr. Jumah’s “history and characteristics,” the district
    No. 08-1931                                               31
    court’s statement of reasons was adequate. See Tr. at 21,
    Apr. 9, 2008.
    Conclusion
    For the reasons stated in this opinion, we affirm in part
    and reverse in part the judgment of the district court and
    remand this case to the district court for re-sentencing. The
    district court shall recalculate the Guidelines based on
    the weight of the pure drugs within the pseudoephedrine
    tablets and impose a sentence accordingly. No other
    aspect of the sentence is subject to further action.
