    Before F LAUM, M ANION, and T INDER, Circuit Judges.
    T INDER, Circuit Judge. Marhsall Blanchard was tried and
    convicted of one count of manufacturing methamphet-
    amine, in violation of 21 U.S.C. §§ 841(a)(1), 841(b)(1)(C),
    and one count of unlawful possession of a firearm by a
    convicted felon, in violation of 18 U.S.C. § 922(g)(1). He
    challenges both convictions on a variety of grounds,
    including the denial of his pretrial motions for a bill of
    particulars and severance, the alleged constructive amend-
    2                                                   No. 07-2780
    ment of the indictment, the sufficiency of the evidence,
    and the introduction at trial of certain comments, orig-
    inally made at a pretrial suppression hearing, by the
    district court judge. Blanchard also challenges his sen-
    tence, contending that the district court erroneously
    applied certain enhancements in calculating the advisory
    guidelines range. For the reasons set forth in this opinion,
    we vacate Blanchard’s convictions and remand for a
    new trial.
    I. Background
    The Defendant, Marshall Blanchard, owned two homes,
    one in Roberts, Illinois, and the other in Paxton, Illinois.
    The two towns are roughly 15 miles apart in east-central
    Illinois. Blanchard acquired and moved into the Roberts
    home no later than sometime during the year 2001, the
    same year in which he separated from his ex-wife.
    With the exception of a seven-month period during 2003,
    Blanchard’s son, Marshall Jr.,1 lived with him at the
    Roberts residence. In the fall of 2001, Marshall Jr. removed
    several firearms—four rifles and two shotguns—from an
    enclosed porch area of the Roberts residence and delivered
    them to a family friend’s place of business for storage. He
    later returned the same firearms to the porch area of the
    Roberts residence, but more on that later.

    Because the Defendant, Marshall Blanchard, and his son,
    Marshall Blanchard Jr., share the same name (apart from the
    “Jr.” designation), for the sake of clarity, we hereinafter refer
    to the Defendant as “Blanchard” and to his son as “Marshall Jr.”
    No. 07-2780                                               3
    After moving out of the Roberts residence in Febru-
    ary 2003, Marshall Jr. returned sometime in August 2003.
    At that time, he was twenty years old and studying
    criminal justice at a local college. During the summer of
    2004, Marshall Jr. began using the porch area of the
    Roberts residence as his bedroom. In order to enjoy
    exclusive access to his bedroom, Marshall Jr. installed a
    lock on the door leading to the porch area from the interior
    of the house and kept the only key for himself. In October
    or November of 2004, Marshall Jr. retrieved the aforemen-
    tioned firearms from the family friend’s place of business
    and returned them to the porch area at the Roberts resi-
    dence. Those firearms remained in the porch area of the
    Roberts residence throughout the remainder of 2004.
    Meanwhile, during the late summer and fall of 2004,
    Marshall Jr. began to notice peculiar physical and behav-
    ioral changes in his father. He noticed that Blanchard lost
    considerable weight, had blemishes and sores on his face,
    did not sleep much, and seemed unusually agitated. In
    addition, Blanchard regularly entertained visitors, some
    of whom Marshall Jr. did not know; however, he did
    know the most frequent visitor, Cynthia Blanding.
    Blanding and Blanchard met in mid-October 2004. At
    that time, Blanding was in the process of moving out of
    her home, from which she had been evicted. Blanding and
    Blanchard became romantically involved, and Blanchard
    offered to let Blanding stay at the house in Paxton, which
    she did on occasion. She also stayed overnight with
    Blanchard on several occasions at the Roberts residence.
    One day in the last week of December 2004, Marshall Jr.
    was home alone at the Roberts residence. He noticed a
    4                                               No. 07-2780
    strong, ammonia-type smell coming from the sink; upon
    inspection, he observed a strainer and some glass jars in
    the sink. The following day, he arrived home early from
    work and discovered two plastic bottles containing an “off-
    white crystal” substance. He opened one of the bottles
    and encountered a strong ammonia-type odor. Marshall Jr.
    recalled information that he had learned about metham-
    phetamine in his criminal justice studies; at this point,
    putting the off-white substance together with his father’s
    recent physical and behavioral changes, he suspected
    that the substance was methamphetamine. Marshall Jr.
    photographed the bottles with his digital camera and took
    a spoon-sized sample of the off-white substance; he then
    went to see his mother, Lori Blanchard. After discussing
    his suspicions and concerns with her, Marshall Jr. left Lori
    with the sample of the off-white substance and a disk
    containing the photos from his digital camera. Lori then
    contacted the Roberts chief of police, Randy Kinzinger, and
    delivered these items to him. The off-white substance
    tested positive for ephedrine, a commonly used ingredient
    in the manufacture of methamphetamine.
    Shortly thereafter, on December 30, 2004, law enforce-
    ment officers executed search warrants at both the
    Roberts and Paxton residences. At both residences, officers
    seized items that, although innocuous when viewed
    individually and in isolation, might nonetheless be used, as
    a group, for methamphetamine manufacturing. At the
    Paxton residence, for example, officers seized camp fuel
    containers, a sulfuric acid container, filters, salt, a gas
    mask, and pseudoephedrine packaging; cleaning officials
    later encountered hazardous substances, including anhy-
    No. 07-2780                                              5
    drous ammonia, at that residence. And at the Roberts
    residence, officers seized, among other things, numerous
    coffee filters, an anhydrous ammonia tank, and a propane
    tank. And not only was there “smoke,” but also “fire”;
    officers seized 9.8 grams of a substance containing meth-
    amphetamine from the Paxton residence and 69 grams of
    a substance containing methamphetamine from the
    Roberts residence. In addition, at the Roberts residence,
    officers seized .01 grams of methamphetamine from the
    nightstand in Blanchard’s bedroom and .10 grams of
    methamphetamine from a plastic plate beneath his bed. At
    the Roberts residence, officers also seized four rifles and
    two shotguns from the aforementioned enclosed porch
    area, and they seized a .32-caliber revolver and ammuni-
    tion from underneath the mattress in Blanchard’s bedroom.
    On April 8, 2005, Blanchard was charged in a federal
    indictment with one count of manufacturing metham-
    phetamine, in violation of 21 U.S.C. §§ 841(a)(1),
    841(b)(1)(C) (Count One), and one count of unlawful
    possession of a firearm by a convicted felon, in violation
    of 18 U.S.C. § 922(g) (Count Two). The indictment alleged
    that both offenses occurred “on or about December 30,
    2004.”
    Blanchard’s trial began on March 27, 2006. At trial, the
    government presented the evidence seized from both
    residences, as well as expert testimony opining that a
    “meth lab” existed at the Paxton residence and that
    materials consistent with the manufacture of metham-
    phetamine were found at the Roberts residence. Marshall
    Jr. testified regarding his observations in late 2004 that
    6                                               No. 07-2780
    led him to suspect that his father was using methamphet-
    amine. He also testified regarding the firearms seized
    from the porch area of the Roberts residence; he ex-
    plained that all but one of the guns belonged to his father,
    that his father controlled and directed both the 2001
    removal and the 2004 retrieval/return of those firearms,
    and that he stopped using the porch area of the Roberts
    residence as his bedroom in September or October 2004,
    allowing his father unfettered access to the porch area
    throughout the remainder of the year. Blanding, testifying
    on behalf of the government pursuant to an immunity
    agreement, testified that Blanchard allowed her to use
    the Paxton residence for methamphetamine manufactur-
    ing, and that in exchange, she supplied him with metham-
    phetamine. In addition, she testified that Blanchard
    sometimes supplied materials and assisted in the manu-
    facturing process. She further testified that on or about
    Christmas Eve 2004, she and Blanchard completed the
    manufacture of a quantity of methamphetamine at the
    Roberts residence. Finally, she testified that Blanchard
    had shown her a handgun that he kept beneath the mat-
    tress in his bedroom at the Roberts residence.
    The trial concluded on March 31, 2006, with the jury
    finding Blanchard guilty on both counts. The district court
    rejected Blanchard’s post-verdict motion for judgment of
    acquittal, characterizing the evidence in support of
    both counts as “overwhelming.” The court sentenced
    Blanchard to 150 months’ imprisonment on Count One
    and 120 months’ imprisonment on Count Two, to be
    served concurrently. In addition, the court sentenced
    Blanchard to three years of supervised release and a $100
    No. 07-2780                                                  7
    special assessment. Blanchard timely filed this appeal,
    challenging both his convictions and his sentence.
    II. Discussion
    On appeal, Blanchard challenges both convictions on
    a variety of grounds, including (1) the denial of his
    pretrial motions for a bill of particulars and a severance;
    (2) an alleged fatal variance between the date specified
    in the indictment and the evidence presented at trial,
    resulting in constructive amendment of the indictment;
    (3) certain statements made by the trial judge at a pretrial
    suppression hearing and subsequently introduced at
    trial; and (4) the sufficiency of the evidence. We address
    these arguments in turn below. Blanchard also chal-
    lenges his sentence, but in light of our conclusion with
    regard to his convictions, we need not address that chal-
    lenge.
    A. Pretrial Motions for Bill of
    Particulars and Severance
    Before trial, Blanchard moved for a bill of particulars
    pursuant to Federal Rule of Criminal Procedure 7(f). The
    indictment alleged that Blanchard committed both the
    methamphetamine manufacturing offense and the fire-
    arms offense “on or about December 30, 2004, in the
    Central District of Illinois.” In moving for a bill of particu-
    lars, Blanchard sought more specific information con-
    cerning the time and place of the alleged offenses, as
    well as the identity of the firearm (or firearms) alleged in
    8                                                  No. 07-2780
    Count Two. The district court denied that motion, finding
    that “the charges are not complex, the indictment is
    sufficiently clear, and Defendant has been provided with
    discovery regarding the charges.” Blanchard now appeals,
    contending that the denial of this motion deprived him of
    an adequate opportunity to prepare for and meet the
    government’s evidence at trial.
    We review the trial court’s discretionary decision to
    deny a motion for a bill of particulars deferentially,
    reversing only upon an abuse of that discretion. United
    States v. Fassnacht, 
    332 F.3d 440
    , 446 (7th Cir. 2003); see also
    United States v. Hernandez, 
    330 F.3d 964
    , 975 (7th Cir. 2003).
    We will reverse only upon a showing of actual prejudice
    to the defendant. 
    Hernandez, 330 F.3d at 975
    .
    Our bill-of-particulars analysis is similar to our con-
    stitutional sufficiency-of-the-indictment analysis; in both
    cases, the key question is whether the defendant was
    sufficiently apprised of the charges against him in order
    to enable adequate trial preparation. See 
    Fassnacht, 332 F.3d at 446
    ; see also 
    Hernandez, 330 F.3d at 975
    (“[A] bill
    of particulars [is] unnecessary where the indictment sets
    forth the elements of the charged offenses and provides
    sufficient notice of the charges to enable the defendant
    to prepare his defense.”). Information relevant to the
    preparation of a defense includes the elements of each
    charged offense, the time and place of the accused’s
    allegedly criminal conduct, and a citation to the statute or
    statutes violated. See 
    Fassnacht, 332 F.3d at 446
    . Where the
    indictment fails to provide the full panoply of such infor-
    mation, a bill of particulars is nonetheless unnecessary
    No. 07-2780                                               9
    if the information “is available through ‘some other
    satisfactory form,’ such as discovery.” 
    Hernandez, 330 F.3d at 975
    (quoting United States v. Canino, 
    949 F.2d 928
    , 949
    (7th Cir. 1992)).
    Because Blanchard had ample access to the information
    necessary to prepare his defense, the district court did not
    abuse its discretion here. Although the indictment was
    somewhat sparse, Blanchard was the beneficiary of exten-
    sive pretrial discovery. For example, he received law
    enforcement reports concerning the searches of his two
    residences, the corresponding search warrants and sup-
    porting documents, and a report of his statements to
    law enforcement officers. Given knowledge of the evi-
    dence seized from both residences and the terms of the
    indictment, Blanchard was undoubtedly aware that the
    government might seek to prove that he manfuctured
    methamphetamine at either residence and that he pos-
    sessed firearms at the Roberts residence on a date approxi-
    mating the “on or about” date alleged in the indictment.
    This was more than sufficient to enable Blanchard to
    prepare for trial. See 
    Fassnacht, 332 F.3d at 446
    (noting
    that “the defendant’s constitutional right is to know the
    offense with which he is charged, not to know the details
    of how it will be proved” (quoting United States v. Kendall,
    
    665 F.2d 126
    , 135 (7th Cir. 1981))). Therefore, the district
    court did not abuse its discretion in denying Blanchard’s
    motion for a bill of particulars.
    Before trial, Blanchard also moved to sever Counts One
    and Two for separate trials pursuant to Federal Rules of
    Criminal Procedure 8(a) and 14. He now appeals the
    10                                                  No. 07-2780
    district court’s denial of that motion, arguing that the
    joinder of the drug and firearms offenses was improper
    and unduly prejudiced him at trial. Although Blanchard
    waived the Rule 14 severance aspect of this motion by
    failing to renew it at the close of the evidence, see United
    States v. Ross, 
    510 F.3d 702
    , 711 (7th Cir. 2007) (ex-
    plaining that a Rule 14 motion for severance is waived if
    not renewed at the close of the evidence), the Rule
    8 misjoinder aspect of the motion, though also not re-
    newed, was properly preserved. See 
    id. at 710
    n.1 (“A
    defendant need not renew a Rule 8 motion at the close
    of the evidence to preserve the argument for appeal.”).
    We review Blanchard’s misjoinder claim de novo,
    focusing on the face of the indictment rather than the
    evidence adduced at trial. 
    Id. at 710;
    see also United States v.
    Lanas, 
    324 F.3d 894
    , 899 (7th Cir. 2003). Federal Rule of
    Criminal Procedure 8(a) permits joinder of offenses
    where they are (1) “of the same or similar character,”
    (2) “based on the same act or transaction,” or (3) “consti-
    tute parts of a common scheme or plan.” We construe this
    rule broadly in the interest of conserving judicial resources
    and avoiding costly, duplicative trials. United States v.
    Nettles, 
    476 F.3d 508
    , 516 (7th Cir. 2007); United States v.
    Rollins, 
    301 F.3d 511
    , 518 n.1 (7th Cir. 2002). Even
    where misjoinder occurs, we will not reverse unless the
    defendant can show actual prejudice—i.e., that the error
    “had substantial and injurious effect or influence in
    determining the jury’s verdict.” 
    Ross, 510 F.3d at 710-11
    (citing United States v. Lane, 
    474 U.S. 438
    , 449 (1986)); see also
    United States v. Hubbard, 
    61 F.3d 1261
    , 1271 (7th Cir. 1995).
    No. 07-2780                                              11
    The first obstacle to Blanchard’s misjoinder argument is
    our presumption that, because of the close relationship
    between drug trafficking and firearms offenses, joinder of
    such offenses is ordinarily proper. See United States v.
    Stokes, 
    211 F.3d 1039
    , 1042 (7th Cir. 2000). This presump-
    tion arises from the “natural inferences that may be
    drawn from the contemporaneous possession of guns
    and drugs or drug paraphernelia: the firearm is an indica-
    tion of drug activity, and participation in drug trafficking
    supplies a motive for having the gun.” 
    Id. (quoting Hub-
    bard, 61 F.3d at 1270
    ). Although that presumption might
    be overcome by, for example, a significant temporal
    disconnect between the alleged offenses, see 
    Hubbard, 61 F.3d at 1271
    (concluding that firearms and narcotics
    charges were misjoined where nearly a year and a half
    transpired between the two offenses), there was no such
    disconnect here; the indictment alleged that the metham-
    phetamine manufacturing and firearms offenses occurred
    at approximately the same time, and evidence of both
    offenses was recovered from the Roberts residence. See
    
    Stokes, 211 F.3d at 1042
    ; United States v. Windom, 
    19 F.3d 1190
    , 1197 (7th Cir. 1994) (explaining that “joinder of a
    weapons offense with drug charges is proper under
    Rule 8(a), especially when the weapons and drugs are
    found in the same search”). Therefore, the district court
    did not err in joining these offenses for trial under
    Rule 8(a).
    Moreover, even if the offenses had been misjoined, the
    error would be harmless because Blanchard cannot show
    prejudice. See, e.g., 
    Ross, 510 F.3d at 710-11
    ; 
    Hubbard, 61 F.3d at 1272
    . Blanchard points out that, absent joinder of
    12                                               No. 07-2780
    the two counts, the drug offense could have been tried
    without informing the jury that he was a convicted felon.
    Conceding this point, we are not convinced that the jury’s
    knowledge of Blanchard’s prior felony conviction had a
    “substantial and injurious effect or influence” on their
    deliberations. 
    Ross, 510 F.3d at 711
    . As we explain in
    further detail below, the evidence of Blanchard’s guilt
    on both counts was considerable, mitigating any risk that
    the jury’s decision was influenced by knowledge that
    Blanchard had previously committed a felony. See 
    id. Furthermore, the
    jury was properly instructed to con-
    sider each count and the corresponding evidence sepa-
    rately, not allowing their decision on one count to color
    their decision on the other. There is no reason to presume
    that they did not adhere to these instructions. Id; see also
    United States v. Coleman, 
    22 F.3d 126
    , 135 (7th Cir. 1994)
    (explaining that where the “jury [is] instructed to con-
    sider each count and the relating evidence separately . . .
    there [is] no reason to suppose that it would disregard
    this mandate” (citation omitted)).
    To recap, the district court did not abuse its discretion in
    denying Blanchard’s motion for a bill of particulars,
    because Blanchard was properly apprised of the charges
    against him and was the beneficiary of extensive pretrial
    discovery that filled in any gaps in the somewhat-sparse
    indictment; thus, he was not denied the opportunity to
    adequately prepare for trial. In addition, Blanchard has
    demonstrated neither misjoinder of the drug and firearms
    counts nor prejudice. Accordingly, the district court did
    not err in joining Counts One and Two for trial. Blanchard
    waived the Rule 14 aspect of his motion by failing to
    No. 07-2780                                            13
    renew it at the close of the evidence, but even if it had
    not been waived, his inability to show prejudice would
    doom this claim as well.
    B. Constructive Amendment of Indictment
    Blanchard next argues that there was a fatal variance
    between the date alleged in the indictment—on or about
    December 30, 2004—and the evidence presented at trial
    regarding the date (or dates) on which he manufactured
    methamphetamine, thereby constructively amending the
    indictment in violation of the Fifth Amendment.
    Blanchard’s argument focuses primarily on Blanding’s
    testimony. At trial, she testified that she manufactured
    methamphetamine with Blanchard on several occasions
    in November and December 2004, and that the last occa-
    sion was on “Christmas Eve or right before Christmas.”
    However, on cross-examination, Blanding conceded that
    she could be no more specific than “on or before Christmas
    Eve,” acknowledging that her memory was impaired
    because she was using methamphetamine regularly in
    late 2004. In addition, a government expert conceded
    on cross-examination that he could not definitively
    state when the “meth lab” at the Paxton residence was
    created, and that it might have been created as many as
    six months earlier. Thus, Blanchard argues, the govern-
    ment’s evidence regarding methamphetamine manu-
    facturing is too temporally indefinite—spanning a period
    of up to six months—to sustain a conviction consistent
    with the “on or about” date alleged in the indictment.
    Constructive amendment of an indictment occurs
    where the permissible bases for conviction are broadened
    14                                               No. 07-2780
    beyond those presented to the grand jury. United States v.
    Folks, 
    236 F.3d 384
    , 390 (7th Cir. 2001). “To avoid running
    afoul of the Fifth Amendment, the allegations in the
    indictment and the proof at trial must match in order ‘to
    insure that the defendant is not subject to a second prose-
    cution, and to give the defendant reasonable notice so
    that he may prepare a defense.’ ” 
    Id. (quoting United
    States
    v. McKinney, 
    954 F.2d 471
    , 480 (7th Cir. 1992)). However,
    where an indictment alleges that an offense occurred “on
    or about” a certain date, “the defendant is deemed to be
    on notice that the charge is not limited to a specific date”
    and “cannot make the requisite showing of prejudice
    based simply on the fact that the government has failed
    to prove a specific date.” 
    Id. at 391
    (quoting United States
    v. Leibowitz, 
    857 F.2d 373
    , 379 (7th Cir. 1988)). Accordingly,
    where the “on or about” language is used, the govern-
    ment need not prove the exact date of the offense “as long
    as a date reasonably near that named in the indictment is
    established.” United States v. Ross, 
    412 F.3d 771
    , 774 (7th
    Cir. 2005) (emphasis added) (reciting the “canonical
    formula” to be applied when the “on or about” language
    is used in the indictment); see also 
    Leibowitz, 857 F.2d at 379
    (citing collected cases).
    The question, then, is whether the government presented
    evidence that would support a date “reasonably near” the
    date specified in the indictment, and we have little
    trouble answering this question in the affirmative.
    Blanding’s testimony—that she and Blanchard manufac-
    tured methamphetamine on approximately December 24,
    2004—provided a reasonable basis for the jury to
    conclude that Blanchard manufactured methamphet-
    No. 07-2780                                               15
    amine within days of the “on or about” date specified in
    the indictment, December 30, 2004. Although Blanding
    conceded on cross-examination that she could not pin-
    point the exact date, such laser-like precision was not
    necessary for her testimony to support a date “reasonably
    near” that alleged in the indictment. See, e.g., 
    Leibowitz, 857 F.2d at 379
    (concluding that 21-day variance between
    date proved at trial and “on or about” date alleged in
    indictment was “reasonably near”). Moreover, the jury
    was expressly instructed not to convict unless they con-
    cluded that Blanchard manufactured methamphetamine
    on a day “reasonably near” that alleged in the indictment.
    Cf. 
    Ross, 412 F.3d at 774-75
    (jury instructions expressly
    permitting more than four-year variance from “on or
    about” date impermissibly amended indictment). Indeed,
    because evidence was presented supporting a date “rea-
    sonably near” that alleged in the indictment, and because
    the jury was properly instructed on this issue, Blanchard’s
    complaint is really directed to the facts found by the
    jury; however, that is a battle that Blanchard lost at trial,
    and which he may not re-fight here on appeal.
    Finally, we note that one of the primary concerns under-
    lying the prohibition on constructive amendments—the
    impairment of the defendant’s ability to prepare his
    defense—is simply not implicated here. See 
    Folks, 236 F.3d at 392
    . As already noted, extensive pretrial discovery
    afforded Blanchard more than sufficient notice of how
    the government might attempt to prove its case at trial.
    Indeed, Blanchard does not argue that he was unfairly
    surprised by the evidence produced or the theories prof-
    fered by the government at trial. For these reasons, there
    was no constructive amendment of Blanchard’s indictment.

    C. Introduction at Trial of Court’s
    Suppression-Hearing Statements
    Blanchard next challenges the introduction at trial of
    certain statements originally made by the trial judge at a
    pretrial suppression hearing, styling his argument in
    terms of both judicial bias and prosecutorial misconduct.
    Before turning to the merits of Blanchard’s arguments on
    this point, some additional background is necessary.
    As already discussed, at trial, Marshall Jr. offered
    testimony that was damaging to his father’s case. With
    respect to the firearms charge, he testified that his father
    owned all but one of the firearms seized from the porch
    area of the Roberts residence (the “porch firearms”), that
    his father directed him to remove those firearms from
    the residence in 2001 and return them in late 2004, and
    that his father enjoyed unfettered access to the porch
    area after September or October 2004. And with respect
    to the methamphetamine manufacturing charge, Marshall
    Jr. testified that he noticed certain physical changes in
    his father, including weight loss and facial sores, in late
    2004. He also testified regarding his discovery of certain
    items in the Roberts residence, including the off-white
    substance that later tested positive for ephedrine, that
    led to the search of Blanchard’s two residences and his
    subsequent arrest.
    At the grand jury hearing nearly one year before trial, in
    April 2005, Marshall Jr. had offered testimony largely
    consistent with his eventual trial testimony. With respect
    to the porch firearms, he testified that Blanchard owned
    them and had ordered Marshall Jr.’s removal of them
    from the Roberts residence in 2001; because Lori
    No. 07-2780                                                17
    (Blanchard’s ex-wife and Marshall Jr.’s mother) had moved
    out of the house, Blanchard, a convicted felon, could no
    longer plausibly deny possession by attributing owner-
    ship to her. Thus, Marshall Jr. and his father moved the
    guns to a family friend’s place of business. When that
    friend died in 2004, Marshall Jr. testified, he obtained a
    Firearm Owner’s Identification (FOID) card so that he
    could retrieve the firearms and return them to the Roberts
    residence while allowing his father, in the event that
    the firearms were discovered by authorities, to plausibly
    deny ownership/possession (distinct concepts which
    Blanchard may have incorrectly conflated).
    However, following the grand jury hearing, at a pretrial
    suppression hearing on November 15, 2005, Marshall Jr.
    offered a remarkably different version of events. He
    testified that the porch firearms originally belonged to
    his mother but had passed down to him when she left
    the Roberts residence; his father was not part of the
    purported chain of ownership. In addition, Marshall Jr.
    testified that he removed those firearms from the Roberts
    residence in 2001 and returned them in 2004 of his own
    volition, without prompting or direction from his father.
    Finally, he testified that in late 2004, the porch area of the
    Roberts residence served as his “apartment,” and he
    enjoyed exclusive access to that area by keeping it locked
    and maintaining possession of the only keys. In short, after
    testifying at the grand jury hearing that his father both
    owned and controlled the porch firearms, Marshall Jr.
    testified at the suppression hearing that his father did not
    own, control, or even have physical access to them.
    18                                              No. 07-2780
    When Marshall Jr. altered his story at the November 15
    suppression hearing, the government (unsurprisingly)
    confronted him with his inconsistent grand jury testi-
    mony. On cross-examination, the government reminded
    Marshall Jr. that he was under oath and asked whether
    he would like to alter his testimony in light of his previous
    grand jury testimony.
    Q. Do you want to change your testimony at all in
    reference to your testimony that this house had
    a separate apartment under your sole control
    and that these guns were yours? Do you want
    to alter that testimony at all?
    A. I, I’m not sure. I don’t, I don’t understand.
    ...
    Q. Do you want to be—do you want to persist in
    stating that this house had been sectioned off
    to where there’s an area—I believe [defense
    counsel] referred to it as an apartment of yours
    that you had sole access to and that these guns
    were, were yours? Do you want to persist in
    that testimony?
    A. Yes.
    (Suppression Hr’g Tr. 85-86.) The government then con-
    fronted Marshall Jr. with specific portions of his prior
    inconsistent testimony, including his indication that his
    father owned the porch firearms. The government also
    reminded Marshall Jr. of his testimony that, in order to
    protect his father (a convicted felon) in the event that the
    firearms were discovered by authorities, he and his
    No. 07-2780                                                19
    father had jointly removed the firearms from the Roberts
    residence in 2001 and then returned them in 2004, only
    after Marshall Jr. had procured an FOID card. During the
    course of this questioning, the court occasionally inter-
    jected its own questions, seeking clarification of Marshall
    Jr.’s answers.
    The trial judge’s comments that are the subject of
    Blanchard’s current challenge came in response to a
    defense counsel objection in the midst of this cross-exami-
    nation. Defense counsel objected when the government
    pointed out that Marshall Jr. had never described the
    Roberts residence porch area as his exclusively controlled
    “apartment” at the grand jury hearing, contending that
    this did not tend to impeach Marshall Jr. The court over-
    ruled that objection, and offered the following explana-
    tory commentary:
    I believe it is [impeachment]. The Court finds it to
    be impeachment. The Court finds this witness not
    to be credible and that the testimony he has given
    today is not credible.
    The Court’s had a chance to observe the manner
    and demeanor of his testimony. The manner and
    demeanor on direct was very assertive. . . . I deter-
    mined that I would ask some questions. And as
    soon as I began questions about the ownership of
    the guns back in 2001—of course, I have no knowl-
    edge of the grand jury testimony—all of a sudden,
    the demeanor began changing dramatically, how
    he hangs his head, how he looks, how his facial
    mannerisms changed; and it was very obvious
    20                                              No. 07-2780
    to me after 13 years of being a criminal lawyer
    and 17 years of being a judge—30 years of being
    experienced—that his answers all of a sudden
    became deceptive, less than credible.
    And, of course, now [the prosecutor] has asked
    him specific questions that lead me to the undeni-
    able conclusion that he has not been credible and,
    because he knew that his answers that he was
    giving were not the same answers he had given
    to the grand jury in April.
    (Suppression Hr’g Tr. 92-93.) And at the conclusion of the
    cross-examination, the government asked, “So would it
    be accurate to say . . . that the testimony you’ve given
    today under oath before this Court has been false and
    misleading?” (Id. 100.) The court intervened, interposing
    a Fifth Amendment objection on Marshall Jr.’s behalf.
    Following the conclusion of the November 15 hearing,
    Marshall Jr. had time to ponder the comments of the court
    and the government, and he became concerned that his
    testimony might lead to legal trouble; soon thereafter, he
    contacted the government’s case agent to express his
    concern. They agreed that Marshall Jr. would meet with
    the case agent and the prosecutor at the government’s
    office, and that meeting took place a few days later. At
    that meeting, the case agent and the prosecutor advised
    Marshall Jr. that they believed he had testified untruthfully
    at the suppression hearing and that he could face perjury
    charges. Marshall Jr. agreed to provide a tape-recorded
    statement correcting those portions of his November 15
    testimony that had been untruthful.
    No. 07-2780                                                21
    On December 12, 2005, at a follow-up hearing to com-
    plete argument on Blanchard’s pending suppression
    motions, the court allowed the government to reopen
    cross-examination of Marshall Jr. On the reopened cross-
    examination, Marshall Jr. recanted those portions of the
    November 15 testimony that had contradicted his grand
    jury testimony. For example, Marshall Jr. testified that
    his father owned almost all of the porch firearms, that his
    father directed the 2001 removal and 2004 return of those
    firearms, and that his father enjoyed unfettered access
    to the porch area beginning sometime around October 2004
    (when Marshall Jr. relocated his bedroom to another part
    of the house). Marshall Jr. also testified that, following his
    grand jury testimony, his father had not-so-subtly pres-
    sured him to change his testimony, telling him that the
    guns were his and that the porch area was his “apartment.”
    As previously noted, at trial, Marshall Jr. testified on
    behalf of the government and offered a version of events
    consistent with his grand jury testimony and his testimony
    at the December 12 hearing. In addition, he explained that
    he had testified untruthfully at the November 15 hearing,
    and that on cross-examination that day, the government
    had exposed discrepancies between his testimony and his
    prior grand jury testimony. He further testified that,
    following the November 15 hearing, he discussed his
    concerns about having testified untruthfully with his
    mother. Then, he explained, he contacted the government
    to express his concern that he might have gotten himself
    into trouble by testifying untruthfully, hoping to “resolve
    the issue.” Marshall Jr. further testified that he was
    recalled to the stand at the December 12 hearing, and at
    22                                              No. 07-2780
    that time, he corrected those portions of his November 15
    testimony that were untruthful.
    As might be expected, defense counsel then sought to
    impeach Marshall Jr.’s testimony by showing his incentive
    to cooperate with the government based upon his fear of
    prosecution for perjury. First, defense counsel asked
    whether, following the November 15 hearing, anyone
    from the government initiated contact with Marshall Jr.
    either before or as he left the courtroom, and he indicated
    that they did not. Defense counsel then asked whether,
    at Marshall Jr.’s meeting with the case agent and the
    prosecutor, the government told him that he could be
    charged with perjury for lying under oath, and he indi-
    cated that they did. He also testified that they discussed
    potential penalties, including a fine and jail time. Marshall
    Jr. acknowledged the “cloud of a perjury charge” that
    followed these conversations and his desire to obtain
    “some mercy for what [he] did” by cooperating with the
    government.
    On redirect, the government immediately sought to
    clarify who had first suggested that Marshall Jr.’s testi-
    mony at the November 15 hearing may have been untruth-
    ful. When Marshall Jr. responded, “The judge and you,”
    the prosecutor was not satisfied; he asked Marshall Jr. if
    he remembered what the judge had said to him. Defense
    counsel promptly objected and requested a sidebar, but
    the judge rejected that request, stating, “No. If I said
    something, it will be in the record, and you have a copy
    of the record. Everybody’s been talking about what
    everybody said. So if you have what I said, it’s on the
    No. 07-2780                                                     23
    record. It can be put before the jury.” (Trial Tr. 221.) Then,
    after a second rejected request for a sidebar,2 and over
    defense counsel’s repeated objections, the prosecutor
    read aloud the entirety of the trial judges’s suppression-
    hearing comments indicating his belief that Marshall Jr.
    was testifying untruthfully. Although we have already
    recounted those comments above and need not repeat
    them in full here, the last of those comments, as quoted by
    the prosecutor at trial, bears repeating:
    And, of course, now [the prosecutor] has asked
    him specific questions that lead me to the undeni-
    able conclusion that he has not been credible
    because he knew that his answers that he was giving
    were not the same answers that he had given to the
    grand jury in April.
    (Trial Tr. 223) (emphasis added).
    Adding another wrinkle to this already unusual event,
    during the prosecutor’s reading of the court’s suppression-
    2
    We have previously expressed our concern that a district
    court’s refusal to entertain any sidebars, particularly where the
    trial judge’s own comments or questions become the subject of
    a potential objection, may put defense counsel in an “awkward
    position.” See United States v. McCray, 
    437 F.3d 639
    , 644 (7th Cir.
    2006) (a case in which the same district judge presided). We
    reiterate that concern here; a full explanation of defense coun-
    sel’s objection in the presence of the jury risked the same
    prejudice to the defendant as the prosecutor’s recitation of the
    court’s comments. Under these circumstances, a sidebar
    could have been particularly useful in “avoid[ing] the risk of
    unforeseen prejudice.” See 
    id. 24 No.
    07-2780
    hearing comments, the trial judge characterized his
    comments, in response to a defense counsel objection and
    in the presence of the jury, as “judicial testimony.” The
    court stated, “It’s my statement. You’ve got the record. Has
    he misread it? . . . It’s a direct statement of the Court in
    a judicial proceeding. You were present. You have a copy
    of it. Has he misread what I said? . . . This is reading
    judicial testimony.” 3 (Trial Tr. 222-23) (emphasis added).
    After the prosecutor finished reading the court’s
    suppression-hearing comments, he asked whether Mar-
    shall Jr. recalled the judge making those comments at the
    November 15 hearing, and Marshall Jr. indicated that he
    did. And the prosecutor pressed further, asking:
    Q. [W]as that the first person to raise any issue
    with you about whether or not you were telling
    the truth?
    A. Yes.
    Q. It wasn’t me, was it?
    A. No.
    Q. It wasn’t [the government’s case agent], was it?
    3
    Given Rule 605’s prohibition on a trial judge offering testi-
    mony, this characterization should have immediately raised red
    flags. See Fed. R. Evid. 605 (“The judge presiding at the trial
    may not testify in that trial as a witness.”). Although Blanchard
    failed to raise this specific objection at trial, he did not need to
    do so in order to preserve the issue for review. See 
    id. (“No objection
    need be made in order to preserve this point.”).

    A. No.
    (Trial Tr. 224.)
    During a break in the proceedings following the con-
    clusion of Marshall Jr.’s testimony, and outside the pres-
    ence of the jury, the trial judge sought to clarify his ratio-
    nale for permitting the introduction of his suppression-
    hearing commentary:
    The Court allowed [the prosecutor] to read the
    Court’s statements into the record because there
    had been much testimony concerning the Novem-
    ber 15th testimony of Marshall Blanchard Jr. . . . .
    [Defense counsel] determined as a trial tactic to
    lead the jury to believe that somehow Mr.
    Blanchard Jr. after he had left court was either
    contacted or discussed with [the prosecutor] or
    [the case agent] for the first time concerning his
    testimony. That clearly opened the door for [the
    prosecutor] to read into the record the Court’s
    comments from November 15th because that was
    clearly the first time Marshall Blanchard was
    confronted with what this Court believed . . . to be
    perjury. . . . I did not want to rule this way on
    the record in front of the jury as to why it was
    allowing [the prosecutor] to proceed because the
    inference of the Court’s ruling could have been
    prejudicial to the defendant. So the Court merely
    wanted [the prosecutor] to read into the record
    accurately and clearly the Court’s comments,
    which were no surprise to [defense counsel]. And
    while [defense counsel] protested loudly, causing
    26                                                No. 07-2780
    the Court to have to make it clear, the only objec-
    tion he could have was whether it was being read
    accurately. I’m doing this out of the presence of
    the jury now so as not to prejudice the defendant
    for the trial tactic that opened the door.
    (Trial Tr. 255-56.)
    Blanchard now contends that the prosecutor’s use at trial
    of the court’s suppression-hearing commentary—what the
    trial judge characterized as his “judicial testimony”—
    amounted to both judicial bias and prosecutorial mis-
    conduct. Blanchard argues that the introduction of the
    court’s statements effectively constituted a judicial en-
    dorsement of the most damaging version of Marshall Jr.’s
    testimony and thereby deprived him of a fair trial. In
    addition, at trial, Blanchard objected on the grounds of
    relevance and unfair prejudice. And there is yet another
    evidentiary issue presented where so-called “judicial
    testimony” is put before the jury, as in this case. See Fed. R.
    Evid. 605. Before considering the broader fair-trial issues,
    we first take up the narrower, threshold evidentiary issues,
    which we review for an abuse of discretion. See United
    States v. Samuels, 
    521 F.3d 804
    , 813 (7th Cir. 2008).
    Federal Rule of Evidence 605 prohibits a presiding
    district court judge from testifying at trial as a witness or
    engaging in equivalent conduct. See United States v. Sliker,
    
    751 F.2d 477
    , 499 (2d Cir. 1984) (discussing the purpose of
    Rule 605 in light of the advisory committee’s notes).
    Although a district court judge may facilitate the jury’s
    understanding of the case by questioning witnesses and
    explaining, summarizing, and commenting on the evi-
    No. 07-2780                                                 27
    dence, United States v. Paiva, 
    892 F.2d 148
    , 159 (1st Cir.
    1989) (citing Quercia v. United States, 
    289 U.S. 466
    , 469-70
    (1933)); United States v. Nickl, 
    427 F.3d 1286
    , 1293 (10th Cir.
    2005), it is improper for the judge to add to the evidence by
    assuming the role of a witness, 
    Nickl, 427 F.3d at 1293
    ;
    
    Paiva, 892 F.2d at 159
    ; 
    Sliker, 751 F.2d at 499
    . Where a trial
    judge’s comments are based upon his own personal
    knowledge of matters external to the trial, those com-
    ments may constitute impermissible judicial testimony.
    See, e.g., United States v. Berber-Tonico, 
    510 F.3d 1083
    , 1091
    (9th Cir. 2007) (concluding that trial judge “violated Rule
    605 when he interjected his own observations” on facts
    which were neither in the record nor reasonably derived
    therefrom, but did not violate Rule 605 where he merely
    summed up the evidence); 
    Nickl, 427 F.3d at 1293
    -94
    (noting that “presiding judge’s commentary . . . added
    new evidence which the prosecution was otherwise
    unable to establish”).
    In this case, we conclude that the introduction of the trial
    judge’s suppression-hearing comments amounted to
    impermissible judicial testimony. First, the judge’s com-
    ments were based upon and incorporated his own
    personal observations of Marshall Jr. at the November 15
    suppression hearing; indeed, the trial judge’s comments
    indicated that his opinion of Marshall Jr.’s credibility was
    based largely upon shifts in Marshall Jr.’s “manner and
    demeanor” that day. Such comments violate Rule 605 by
    “add[ing] new evidence which the prosecution was
    otherwise unable to establish.”

    Berber-Tonico, 510 F.3d at 1091

    While it is true that the prosecutor, rather than the
    trial judge, read the judge’s suppression-hearing com-
    ments into the record at trial, this in no way alters our
    conclusion. In the presence of the jury, the trial judge
    acknowledged that the suppression-hearing comments
    were his own, insisted that the only valid objection to the
    comments’ introduction could be if they were not read
    “word for word,” and characterized the comments as his
    “judicial testimony.” Under such circumstances, Rule 605
    is violated; the rule would serve little purpose if it were
    violated only where a judge observes all the formali-
    ties—taking of an oath, sitting in the witness chair, etc.—of
    an ordinary witness. Cf. 
    Nickl, 427 F.3d at 1292-93
    (finding
    that the trial judge violated Rule 605 when he interrupted
    the cross-examination of a witness and offered, in
    response to defense counsel’s question, his own opinion
    on an ultimate factual issue).
    Before turning to our harmless error analysis, we pause
    to consider Blanchard’s additional argument that the
    danger of unfair prejudice from the “judicial testimony”
    significantly outweighed its probative value, compelling
    exclusion. See Fed. R. Evid. 403. We first note that the
    trial judge’s suppression-hearing comments were of
    minimal relevance; the saga of Marshall Jr.’s shifting
    testimony was already before the jury, and the judge’s
    credibility evaluation had little, if any, “tendency to make
    the existence of any [material fact] more probable or less
    probable than it would [have been] without the evidence.”
    See Fed. R. Evid. 401. The government concedes as much
    by not arguing that this evidence had any independent
    relevance; instead, following the district court’s rationale,
    No. 07-2780                                                  29
    the government insists that defense counsel “opened the
    door” to this line of questioning. The government cites
    to United States v. Peco, 
    784 F.2d 798
    , 805 (7th Cir. 1986), for
    the proposition that “[w]hen a party opens up a subject,
    even though it may not be strictly relevant to the case, he
    cannot complain on appeal if the opposing party intro-
    duces evidence on the same subject.” 
    Id. (quoting United
    States v. Carter, 
    720 F.2d 941
    , 948 (7th Cir. 1983)). And the
    government asserts that defense counsel’s cross-examina-
    tion of Marshall Jr. opened the door to its attempt to
    show that it was the district court, rather than the gov-
    ernment, who first challenged Marshall Jr.’s truthfulness
    at the November 15 hearing.
    We disagree. Although the trial transcript reveals that
    defense counsel asked Marshall Jr. whether anyone
    from the government initiated contact with him
    following the November 15 hearing, he responded in the
    negative. Indeed, Marshall Jr. indicated that he contacted
    the government on his own, after discussing his con-
    cerns with his mother, in an effort to correct his testimony.
    And although Marshall Jr. then testified that, at his meet-
    ing with the government, they discussed potential
    perjury charges and corresponding penalties, this went to
    the issue of Marshall Jr.’s motivation for changing his
    testimony, not the issue of who first suggested that he
    had been untruthful at the November 15 hearing.
    In addition, the government’s “open the door” argument
    rests upon a flawed factual premise; in fact, it was the
    government, not the trial judge, who first challenged
    Marshall Jr.’s truthfulness when the prosecutor con-
    30                                             No. 07-2780
    fronted Marshall Jr. with his prior inconsistent grand
    jury testimony at the November 15 hearing. In so doing,
    the government repeatedly asked Marshall Jr. whether,
    in light of his earlier testimony, he wished to change any
    of his testimony that day. It was only after defense
    counsel objected to this line of questioning that the court
    offered its own opinion of Marshall Jr.’s truthfulness.
    Moreover, even if defense counsel had somehow inti-
    mated on cross-examination that the government first
    challenged Marshall Jr.’s truthfulness, this would have
    come as no great surprise to the jury, because the govern-
    ment’s direct examination of Marshall Jr. seemed to
    establish just that:
    Q. [A]fter [defense counsel] finished asking you
    his questions [at the November 15 hearing],
    did I have an opportunity to ask you ques-
    tions?
    A. Yes.
    Q. And did you know at the time that, whether or
    not the government had in its possession a full
    transcript of everything you said before the
    grand jury?
    A. I was—I was pretty sure you did, but I wasn’t
    sure entirely.
    Q. And when I asked you questions that day, did
    I ask you, or point out and ask you to explain
    the difference between what you told the
    grand jury under oath six months earlier and
    what you told the judge under oath that day?
    No. 07-2780                                                  31
    A. Yes.
    Q. Did I ask you those questions?
    A. Yes.
    Q. Were you able to explain the difference?
    A. No.
    Q. How was that day for you?
    A. One of the worst days of my life.
    (Trial Tr. 128-29.) The absence of a factual underpinning
    for the government’s argument only strengthens our
    conclusion; there was no compelling justification for
    the introduction of the court’s statements.
    And a compelling justification was required, because
    not only was the trial judge’s suppression-hearing com-
    mentary of dubious relevance, but the danger of unfair
    prejudice was unquestionably high. See Fed. R. Evid. 403
    (relevant evidence “may be excluded if its probative
    value is substantially outweighed by the danger of unfair
    prejudice”). As explained further below, the introduction
    of this evidence risked placing the weight of the court’s
    authority behind the government-friendly version of
    Marshall Jr.’s testimony; thus, there was a significant risk
    of unfair prejudice to the defendant. Cf. United States v.
    Martin, 
    189 F.3d 547
    , 553 (7th Cir. 1999) (“Because trial
    judges wield substantial influence over juries . . . . [a] judge
    cannot assume the role of an advocate for either side . . . .”).
    Therefore, we conclude that the introduction of the
    trial judge’s suppression-hearing comments was erro-
    neous under Rules 605 and 403, and the only re-
    32                                               No. 07-2780
    maining question is whether this error was nonetheless
    harmless. “The test for harmless error is whether, in the
    mind of the average juror, the prosecution’s case would
    have been significantly less persuasive had the improper
    evidence been excluded.” United States v. Emerson, 
    501 F.3d 804
    , 813 (7th Cir. 2007) (internal quotation marks
    omitted) (quoting United States v. Owens, 
    424 F.3d 649
    , 656
    (7th Cir. 2005)); see also Fed. R. Crim. P. 52(a) (“Any
    error . . . that does not affect substantial rights must be
    disregarded.”). At the outset, we note that it is difficult to
    imagine a scenario in which the court’s pronouncements
    on the credibility of a key government witness could fail
    to influence the jury. Indeed, Rule 605 is intended to
    guard against the “prejudice which may arise . . . because
    of the judge’s influential position with the jury.” 
    Nickl, 427 F.3d at 1293
    (citing Fed. R. Evid. 605 advisory committee’s
    note). And the magnitude of this influence is difficult to
    overstate; as the Supreme Court has explained, “The
    influence of the trial judge on the jury is necessarily and
    properly of great weight and his lightest word or intima-
    tion is received with deference, and may prove control-
    ling.” 
    Quercia, 289 U.S. at 470
    (internal quotation omitted);
    see also United States v. Curry, No. 07-2455, slip op. at 14
    (7th Cir. Aug. 15, 2008) (noting that, because “trial judges
    wield substantial influence over juries,” a judge “should
    take special care not to indicate his beliefs about a wit-
    ness’ honesty” (quotation omitted)); 
    Martin, 189 F.3d at 553
    (noting judge’s “substantial influence” over jury and
    consequent need for the judge to avoid assuming the
    role of advocate); United States v. Hickman, 
    592 F.2d 931
    ,
    933 (6th Cir. 1979) (noting that a trial judge’s “position
    before a jury is overpowering”).
    No. 07-2780                                               33
    The potentially “overpowering” influence of the trial
    judge on the jury takes on added significance because of
    the nature of Marshall Jr.’s shifting testimony in this case.
    His pretrial and trial testimony presented essentially two
    stories; first, at the grand jury hearing, he told the story
    favorable to the government. He then reversed course at
    the November 15 suppression hearing, contradicting
    portions of his grand jury testimony in a manner that
    strengthened his father’s defense. He then reversed course
    once again, disavowing his November 15 testimony and
    essentially re-adopting the story he told before the
    grand jury, a story that he stuck to at trial. And naturally,
    defense counsel sought to show on cross-examination that
    Marshall Jr. had an incentive to change his November 15
    testimony after discussing potential perjury charges with
    the government. Given this context, the introduction of
    the trial judge’s earlier comments—expressing his unequiv-
    ocal belief that Marshall Jr. was untruthful in departing
    from his grand jury testimony at the November 15
    hearing—conveyed, at a minimum, judicial disapproval
    of the most defendant-friendly version of Marshall Jr.’s
    testimony. At worst, it effectively stamped the
    government-friendly version of Marshall Jr.’s testimony
    with the seal of judicial imprimatur. In this vein, the last
    statement from the court’s suppression-hearing com-
    ments—indicating the court’s belief that Marshall Jr. was
    not credible “because he knew that his answers that he
    was giving were not the same answers that he had given to the
    grand jury in April” (Trial Tr. 223) (emphasis added)—is
    particularly damning, because it seemingly endorses the
    government-friendly version of Marshall Jr.’s testimony.
    34                                                No. 07-2780
    Thus, in allowing his suppression-hearing comments to
    come in before the jury, the trial judge placed not just a
    thumb, but a very heavy fist, on the scales of justice,
    tipping the balance firmly in the government’s favor. Cf.
    United States v. Verser, 
    916 F.2d 1268
    , 1272-73 (7th Cir. 1990)
    (“Fundamental to the right to a fair trial” is the court’s
    obligation to avoid “giv[ing] the impression to the jury
    that the judge believes one version of the evidence and
    disbelieves or doubts another.” (quotation omitted)).
    And Marshall Jr. was not just a key government witness,
    but, at least with respect to the firearms charge, the star;
    his testimony was crucial to establishing Blanchard’s
    control over the porch firearms. Although the handgun
    seized from Blanchard’s bedroom might provide an
    independent basis to sustain the firearms conviction
    for sufficiency-of-the-evidence purposes, see United
    States v. Alanis, 
    265 F.3d 576
    , 592 (7th Cir. 2001) (finding
    recovery of gun from defendant’s bedroom constituted
    sufficient evidence of constructive possession), the gov-
    ernment focused its efforts at trial on the porch firearms.
    Marshall Jr.’s testimony regarding his father’s ownership,
    control of, and access to those firearms was the lynchpin
    of the government’s case. And although Marshall Jr.’s
    testimony was somewhat less important with respect to
    the methamphetamine manufacturing charge, it was
    nonetheless significant. Without his testimony, the gov-
    ernment’s case would have rested even more heavily on
    Blanding, a witness whose credibility was somewhat
    compromised by the jury’s knowledge that she was a
    past methamphetamine user who had entered into an
    immunity agreement with the government. Blanding’s
    account of the manufacturing arrangement—that
    No. 07-2780                                                 35
    Blanchard facilitated and participated in the manu-
    facture of methamphetamine in exchange for a share of
    the product—was bolstered by Marshall Jr.’s testimony
    regarding his father’s behavioral and physical changes;
    those changes supported an inference of the sort of
    regular methamphetamine use that might motivate one
    to encourage and participate in manufacture at his own
    residence. Thus, the prejudicial effect of the court’s argu-
    able endorsement of Marshall Jr.’s grand jury testimony
    cannot be neatly confined to the felon-in-possession charge.
    The government’s emphasis on Marshall Jr.’s testimony
    at trial confirms his importance to the government’s
    overall case. He was not only the first witness called by
    the government at trial, but also a point of emphasis in
    closing argument, where the prosecutor stated: “Finally
    and most importantly, you have to consider the testi-
    mony of the defendant’s own son. . . . There can be no
    more compelling evidence in this case than the testimony
    of Marshall Jr., the agony that was vivid from his testi-
    mony.” (Trial Tr. 871, 873.) The prosecutor reminded
    the jury that Marshall Jr. had testified unfavorably to his
    father before the grand jury with respect to both the
    drug manufacturing and felon-in-possession charges
    before changing his testimony at the November 15 hear-
    ing. Then, the prosecutor delivered a final reminder of the
    trial judge’s suppression-hearing comments: “On Novem-
    ber 15th of last year, Marshall Jr. comes into this courtroom
    before [the trial judge] and lies under oath for his dad. . . .
    And it wasn’t the government who suggested—who first
    suggested that he wasn’t telling the truth. You heard what
    happened during that hearing.” (Trial Tr. 872) (emphasis
    added). This comment provided one last, potentially
    36                                                  No. 07-2780
    devastating reminder that the trial judge had effectively
    endorsed the grand-jury, government-friendly version of
    Marshall Jr.’s testimony.
    And finally, the court did not instruct the jury in a
    manner sufficient to remedy the potential prejudice.
    First, the court failed to provide a timely limiting instruc-
    tion (or any at all, for that matter) directing the jury to
    consider the court’s suppression-hearing comments only
    for the purpose of establishing who first challenged
    Marshall Jr.’s truthfulness.4 See 
    Nickl, 427 F.3d at 1295
    (finding Rule 605 violation was not harmless partly
    because “the judge offered no specific curative instruc-
    tion which could have overcome his error”); cf. Curry,
    No. 07-2455, slip op. at 16-17 (where trial judge’s explana-
    tion of the concept of hearsay might have been inter-
    preted as impugning the credibility of the defendant,
    immediate and lengthy curative instruction helped to
    avoid reversible error, although it was noted to be a “close
    call”). Where the court’s comments were introduced only
    4
    The trial judge’s failure to provide a timely limiting instruc-
    tion is particularly puzzling in light of his decision to promptly
    “complete the record” at the next break in the proceedings.
    Outside the presence of the jury, he explained that he had
    permitted the introduction of his suppression-hearing comments
    solely for the limited purpose of establishing who first chal-
    lenged Marshall Jr.’s truthfulness at the November 15 hearing.
    If the limited purpose of this evidence was of such importance
    that it required a detailed explanation in the record, then
    surely it was significant enough to merit a timely limiting
    instruction to the jury.
    No. 07-2780                                                37
    for this limited purpose, rather than the broader purpose
    of sharing the court’s credibility evaluation of a crucial
    government witness, such an instruction may have been
    helpful in alleviating the potential prejudice. Cf. United
    States v. Simpson, 
    479 F.3d 492
    , 500 (7th Cir. 2007) (discuss-
    ing failure to provide limiting instruction in analogous
    Rule 404(b) context). In the final jury instructions, the
    court did offer the following generic instructions:
    Nothing I say now and nothing I said or did during
    the trial is meant to indicate any opinion on my
    part about what the facts are or about what your
    verdict should be. The evidence consists of the
    testimony of the witnesses, the exhibits admitted
    in evidence, and a stipulation.
    See Seventh Circuit Pattern Criminal Jury Instructions 1.01,
    1.02 (1999). In the unusual context presented here, we
    find these instructions insufficient to remedy the
    potential prejudice. First, although we ordinarily presume
    that jurors follow instructions, see 
    Ross, 510 F.3d at 711
    , it
    is impossible to say—particularly in light of the trial
    judge’s characterization of his comments as “judicial
    testim ony”— w hether a layperson juror w ou ld
    interpret these instructions as a command to disregard
    the so-called “judicial testimony” or an invitation to treat
    it as evidence. Second, even if the trial judge had not
    characterized his comments as “judicial testimony,” it is
    doubtful that these generic instructions would have
    been sufficient, because they were “neither prompt,
    specific, nor emphatic.” 
    Nickl, 427 F.3d at 1295
    (finding
    similar generic instruction insufficient to cure prejudice
    38                                                No. 07-2780
    caused by Rule 605 violation); see also 
    Quercia, 289 U.S. at 472
    (“Nor do we think that the error was cured by the
    statement of the trial judge that his opinion of the evi-
    dence was not binding on the jury . . . . His definite and
    concrete assertion of fact, which he had made with all the
    persuasiveness of judicial utterance . . . was not with-
    drawn.”).
    In short, we conclude that the trial judge abused his
    discretion by allowing the introduction of his own
    suppression-hearing comments on the credibility of a key
    government witness, and this error was not harmless. In
    light of this conclusion, we need not reach the question
    of whether this error constituted judicial bias or pros-
    ecutorial misconduct. However, this case sounds a cau-
    tionary note for district court judges, who must remain
    alert to the potential impact of their comments on juries
    and the consequent need to avoid the appearance of
    partiality to either side. See 
    McCray, 437 F.3d at 643
    ;
    United States v. Washington, 
    417 F.3d 780
    , 784 (7th Cir.
    2005).
    D. Sufficiency of the Evidence
    Before concluding, we briefly address Blanchard’s
    sufficiency-of-the-evidence challenge to both convic-
    tions.5 In challenging the sufficiency of the evidence,
    5
    In light of our conclusion regarding the improper introduc-
    tion of the court’s suppression-hearing comments, this might

    Blanchard faces a “daunting task.” United States v.
    Wortman, 
    488 F.3d 752
    , 754 (7th Cir. 2007) (citation omit-
    ted). On review of such a challenge, we view the evidence
    and all reasonable inferences derived therefrom in the
    light most favorable to the government, defer to the
    jury’s credibility determinations, and overturn a verdict
    “only when the record contains no evidence, regardless
    of how it is weighed, from which the jury could find guilt
    beyond a reasonable doubt.” United States v. Duran, 
    407 F.3d 828
    , 839 (7th Cir. 2005) (quoting United States v.
    Jackson, 
    177 F.3d 628
    , 630 (7th Cir. 1999)); see also United
    States v. Wantuch, 
    525 F.3d 505
    , 519 (7th Cir. 2008). In other
    words, we will reverse “only if the fact finder’s take on
    the evidence was wholly irrational.” United States v.
    Bustamante, 
    493 F.3d 879
    , 884 (7th Cir. 2007) (internal
    quotation omitted).
    Under this exceedingly deferential standard of review,
    we conclude that the district court did not err in denying
    Blanchard’s Rule 29 sufficiency-of-the-evidence motion.
    Blanding’s testimony, coupled with the methamphetamine-
    related evidence recovered from both Blanchard’s resi-
    dences, provided evidence in support of Count One. And
    Marshall Jr.’s testimony, coupled with the seizure of the
    firearms from Blanchard’s Roberts residence, provided
    evidence of constructive possession of the porch fire-
    5
    (...continued)
    appear unnecessary. However, if Blanchard prevailed on this
    challenge, he would be entitled to a judgment of acquittal, and
    therefore, we find it appropriate to address his argument.

    arms, in support of Count Two. See United States v. Thomas,
    
    321 F.3d 627
    , 636 (7th Cir. 2003) (constructive possession
    exists where one has “the power and the intention at
    a given time to exercise dominion and control over an
    object, either directly or through others” (quotation
    omitted)); 
    Bustamante, 493 F.3d at 889
    (explaining that the
    government “can prove constructive possession of a gun
    by showing that police recovered the gun at the defen-
    dant’s residence” (citing United States v. Kitchen, 
    57 F.3d 516
    , 521 (7th Cir. 1995)). In sum, this evidence provided
    a sufficient, rational basis for the case to go to the jury
    for deliberation; indeed, absent the strange and unusual
    events described in the foregoing section, Blanchard’s
    convictions would be affirmed. However, that the jury’s
    decision may have been rational does not mean that it
    was inevitable, and because we are troubled that the
    introduction of the trial judge’s suppression-hearing
    commentary may have influenced the outcome of the trial,
    Blanchard’s convictions cannot stand.6
    6
    We briefly address two additional arguments that were
    included, almost as an afterthought, at the close of the Appel-
    lant’s brief. Blanchard argues that his civil and possessory rights
    have been fully restored under Illinois law, precluding his
    conviction under 18 U.S.C. § 922(g)(1), but acknowledges that
    his argument is foreclosed by our decision in Melvin v. United
    States, 
    78 F.3d 327
    (7th Cir. 1996). He also contends (without
    explanation or citation to authority) that § 922(g)(1) exceeds the
    scope of Congress’s power under the Commerce Clause. But
    “movement in interstate commerce is all the Supreme Court

    III. Conclusion
    For the foregoing reasons, we V ACATE the Defendant’s
    convictions and R EMAND for a new trial. Circuit Rule 36

    interstate movement of the firearms presented at trial. Blanchard
    indicates that he has raised these arguments in order to
    preserve them in the event of a change in the law, and we
    reciprocate his perfunctory development of these arguments
    with our rejection of them here.
