    Before O ’BR IEN , M cW ILL IAM S and M cCO NNELL, Circuit Judges.
    O ’Brien, Circuit Judge.
    During an inspection of Charles Ellwood Gwathney’s comm ercial truck,
    Officer James Smid of the New M exico M otor Transportation Division discovered
    152.5 kilograms of marijuana. Gwathney was convicted by a jury of possession
    of 100 kilograms or more of marijuana, in violation of 
    21 U.S.C. § 841
    (b)(1)(b)(vii). He challenges the district court’s denial of his motion to
    suppress evidence obtained from the search, the admission of certain government
    evidence, the giving of a “permissive inference” jury instruction, and the district
    court’s denial of his motion for a new trial based on newly discovered evidence.
    W e affirm.
    Background:
    On M ay 23, 2004, Gwathney, a commercial truck driver, stopped at the
    Gallup, New M exico Port of Entry along Interstate 40 near the Arizona-New
    M exico state line to obtain a trip permit through New M exico for his load of
    potatoes. 1 The truck was owned by Solomon Shaw. Officer Smid asked
    Gwathney for his driver’s license, medical card, tractor and trailer registration,
    log book and bill of lading, all of which were provided. The bill of lading listed
    the truck as carrying 833 boxes of red potato creamers, required the truck to be
    maintained at forty-two degrees and was signed by Gwathney. The log book

    “New M exico law requires all comm ercial carriers entering or leaving
    New M exico to stop at all ports of entry.” United States v. Vasquez-C astillo, 
    258 F.3d 1207
    , 1209 (10th Cir. 2001) (citing N.M . Stat. Ann. § 65-5-1(A)). “The
    state authorizes personnel assigned to the ports of entry to inspect comm ercial
    vehicles and their documentation to determine whether the vehicles, drivers, and
    cargo are in compliance with state laws regarding public safety, health, and
    welfare.” Id. (citing N.M . Stat. Ann. § 65-5-1). “New M exico has also
    authorized its employees to enforce federal laws relating to comm ercial motor
    vehicle carriers.” Id. at 1211 (citing N.M . Stat. Ann. § 65-1-9).

    indicated potatoes had been loaded on the truck in Phoenix on M ay 21, but that
    Gwathney did not leave Phoenix until M ay 23. Although the truck was
    refrigerated, Officer Smid thought it unusual Gwathney would load the potatoes
    prior to having his truck repaired because potatoes are perishable goods. 2 Officer
    Smid asked Gwathney why he had taken over a day to leave Phoenix after his
    truck was loaded. Gwathney explained the delay was caused by repairs he had
    made to his truck. Gwathney provided Officer Smid an invoice for the repair
    work. The invoice showed the repair work to have been completed on M ay 21. It
    also indicated G wathney paid almost $14,000 in cash for the repairs.
    Officer Smid instructed Gwathney to pull the truck into a bay where he
    would conduct a level 2 inspection. 3 After checking the outside of the truck,
    Officer Smid instructed Gwathney to unlock the doors to the trailer. Upon
    opening the doors, Officer Smid discovered one of the pallets had tipped against
    the wall of the truck during transit. Officer Smid used a ladder to climb over the
    potatoes to make sure the rest of the pallets w ere secure and in place. W hile
    climbing over the leaning pallet, Officer Smid detected shoe prints and crushed
    boxes indicating someone had walked on the pallets after they were loaded on the
    truck. Officer Smid followed the footprints and smashed boxes until he reached

    Officer Smid also testified the refrigeration unit on Gwathney’s trailer
    was leaking and “in bad shape.” (R. Supp. Vol. I at 75.)

    “Inspectors conduct three levels of inspections at the inspection bays. O f
    these, Level 1 is the most thorough.” Vasquez-C astillo,

    an open area in the truck. There, he discovered several large non-conforming
    brow n boxes that had numbers spray-painted on them and were wrapped in brow n
    packing tape. They did not have the word “Potato” on them, and Officer Smid
    believed them to contain contraband. 4 At that point, Officer Smid crawled out of
    the truck and handcuffed Gwathney for the officer’s protection while he
    continued his search. Upon returning to the boxes, Officer Smid cut them open
    and discovered what eventually was determined to be 152.2 kilograms of
    marijuana. 5 Officer Smid then arrested Gwathney.
    On August 11, 2004, Gwathney was indicted for possession with intent to
    distribute 100 kilograms or more of marijuana in violation of 
    21 U.S.C. §§ 841
    (a)(1) and (b)(1)(B). On August 30, 2004, Gwathney filed a motion to
    suppress the evidence found in the commercial trailer. H e argued Officer Smid
    lacked probable cause to conduct a special safety search. After an evidentiary
    hearing, the district court denied Gwathney’s motion.
    Beginning December 15, 2004, Gwathney was tried before a jury. At trial,
    Gwathney claimed he had no knowledge of the drugs on his truck. He explained
    the payment of $14,000 in cash for the truck repairs came from money wired to
    4
    The potatoes were loaded on pallets, packed in white boxes, marked as
    “Potato,” and had handles allowing the contents to be visible. (R. Vol. III at 44.)
    5
    The value of the drugs in Phoenix, the source of the load, was estimated at
    $168,000 to $252,000. The value of the drugs in New York, the destination of the
    load, was estimated at $336,000 to $672,000.

    him by Solomon Shaw, who sent the money via W estern Union. In rebuttal, the
    government introduced Exhibit 55 - an administrative subpoena directed toward
    W estern Union requiring the provision of any wire transfer records for Gwathney,
    or Solomon Shaw from M ay 13, 2004 through M ay 23, 2004, coupled with
    W estern Union’s response that it could find no such records. Gwathney objected
    to the admission of the evidence based on the lack of an adequate foundation.
    The district court allowed admission of W estern Union’s response based on the
    business record exception of Rule 803(6) of the Federal Rules of Evidence.
    At the close of the case, the district court gave the jury a permissive
    inference instruction pertaining to Gwathney’s knowledge of the marijuana in his
    truck. Jury Instruction 13 provided:
    W ith respect to the question of whether or not a defendant knew that the
    controlled substance was present, you may - but are not required to -
    infer that the driver and sole occupant of the tractor-trailer rig has
    knowledge of the controlled substance within it. This inference does
    not relieve the government of its obligation to prove all of the elements
    of the offense beyond a reasonable doubt.
    (R. Supp. Vol. II at 355-56.) On December 16, 2004, the jury convicted
    Gwathney.
    On M ay 11, 2005, Gwathney filed a motion for a new trial based on newly
    discovered evidence. The new evidence was a W estern Union wire transfer
    receipt showing a transfer of $921.00 from Solomon Shaw to Gwathney on M ay
    14, 2004, w hich contradicted Western Union’s report attached to Exhibit 55. O n
    -5-
    M ay 25, 2005, the district court denied the motion. On M ay 27, 2005, Gwathney
    was sentenced to 137 months’ imprisonment. He filed a timely notice of appeal
    on June 1, 2005.
    Discussion:
    Gwathney challenges the district court’s denial of his motion to suppress,
    the admission of Exhibit 55 into evidence, jury instruction number 13 and the
    district court’s denial of his motion for a new trial. W e consider each in turn.
    I. M otion to Suppress
    W e review warrantless searches under the Fourth Amendment for
    reasonableness. Reasonableness is a question of law we review de novo. United
    States v. Long, 
    176 F.3d 1304
    , 1307 (10th Cir. 1999). W e accept the district
    court’s factual findings unless clearly erroneous and view the evidence in the
    light most favorable to the district court’s determination. 
    Id.
    W hen w arrantless searches of closely regulated industries are at issue, we
    apply the test articulated by the Supreme Court in New York v. Burger, 
    482 U.S. 691
     (1987). See United States v. Johnson, 
    408 F.3d 1313
    , 1320 (10th Cir.), cert.
    denied, 
    126 S.Ct. 458
     (2005); Vasquez-C astillo, 
    258 F.3d at 1210
    . Commercial
    trucking is a closely regulated industry. United States v. Burch, 
    153 F.3d 1140
    ,
    1141-43 (10th Cir. 1998). Thus, under Burger, a warrantless search of a
    comm ercial truck satisfies the Fourth Amendment where: (1) there is a substantial
    government interest underlying a regulatory scheme authorizing the search, (2)
    -6-
    the warrantless search is necessary to further the regulatory scheme, and (3) the
    inspection program provides a constitutionally adequate substitute for a warrant.
    Burger, 
    482 U.S. at 701-03
    ; Vasquez-C astillo, 
    258 F.3d at 1210
    .
    The search at issue in this case is almost identical to the one we confronted
    in Vasquez-C astillo. There we examined the level 1 inspection of a commercial
    truck by the New M exico M otor Transportation Division at its port of entry along
    Interstate 40 on the opposite side of the state near San Jon, New M exico.
    Vasquez-C astillo, 
    258 F.3d at 1208-09
    . That inspection revealed 800 pounds of
    marijuana concealed in a hidden compartment in the trailer. 
    Id. at 1210
    . W e
    applied the Burger test to analyze whether the inspection officer’s warrantless
    entry into the truck was justified. Relying on our previous decision in V-1 Oil
    Co. v. M eans, we noted that “‘[t]he state clearly has a substantial interest in
    regulating commercial carriers to protect public safety on the highways.’”
    Vasquez-C astillo, 
    258 F.3d at 1211
     (quoting M eans, 
    94 F.3d 1420
    , 1426 (10th
    Cir. 1996)). Thus, we held New M exico’s “safety inspections of commercial
    carriers satisfy the first prong of the Burger test.” 
    Id.
     W e also held New
    M exico’s “routine safety inspections [w ere] necessary to further the regulatory
    scheme governing commercial carriers,” thus satisfying the second prong of the
    Burger test. 
    Id.
     Finally, we examined New M exico’s requirement that “all
    comm ercial motor vehicle carriers stop at every point of entry” and the
    -7-
    authorization to inspect blocking and bracing inside the trailer, 6 and held the
    regulations provided adequate notice to owners of commercial property it would
    be subject to periodic inspections for specific purposes, limited in time, place and
    scope. Id. at 1211, 1212 (discussing N.M . Stat. Ann. § 65-5-1). Thus, New
    M exico’s commercial inspection system satisfied the third Berger prong.
    Consequently, we upheld the warrantless search of the trailer at issue in Vasquez-
    Castillo.
    The analysis in Vasquez-C astillo largely controls the outcome in this case.
    As we observed there, New M exico’s regulatory scheme clearly contemplates
    entrance into the trailer to inspect blocking and bracing, and also allows
    inspection of the contents of the vehicle. See N.M . Stat. Ann. §65-5-1(F). 7 W hile
    in Vasquez-C astillo we held New M exico’s scheme as to the inspection of
    blocking and bracing satisfied the Burger test for warrantless searches, we
    6
    “Along with numerous other requirements, both federal and New M exico
    regulations require proper blocking and bracing.” Vasquez-C astillo, 
    258 F.3d at
    1211 (citing 
    49 C.F.R. § 393.104
     & N.M . Admin. Code § 18.2.3.13). “Proper
    blocking and bracing ensures that the cargo is secured so that, when the vehicle
    decelerates . . ., the cargo is protected against shifting sideways in transit.”
    Burch, 
    153 F.3d at
    1142 n.2 (quotation omitted). “‘To check blocking and
    bracing, an officer must inspect the interior of a trailer.’” Vasquez-C astillo, 
    258 F.3d at 1211
     (quoting Burch, 
    153 F.3d at
    1142 n.2).
    7
    “To determine whether the vehicle is safe, those in charge of the port of
    entry are permitted to ‘inspect the vehicle and its contents to determine whether
    all laws and all rules and regulations of the departments of [New M exico] w ith
    respect to public safety, health, welfare and comfort have been fully complied
    with.’” Vasquez-C astillo, 
    258 F.3d at 1211
     (quoting N.M . Stat. Ann. § 65-5-1(F)).
    -8-
    specifically reserved the question of whether the regulatory authorization to
    inspect the cargo inside the trailer w ould also have justified entry. 
    258 F.3d at
    1212 n.3. W e see no reason, and Gwathney fails to provide a convincing one, to
    analyze the entry into the trailer to inspect blocking and bracing differently than
    the inspection of the cargo when the statutory scheme authorizing both was
    generally approved of in Vasquez-C astillo. “The Burger criteria apply to a
    regulatory scheme generally, not to the particular search at issue.” United States
    v. M aldonado, 
    356 F.3d 130
    , 136 (1st Cir. 2004). “In other words, the Burger
    criteria are applied generally to a statutory scheme, not to a given set of facts
    arising under that scheme.” 
    Id.
     Thus, Officer Smid was justified in entering the
    trailer to inspect the cargo pursuant to his regulatory duty to inspect the contents
    of the trailer. See N.M . Stat. Ann. § 65-5-1(F); Johnson, 
    408 F.3d at 1322
    (general state administrative search scheme covering salvage yards satisfied
    Burger and allowed agents to inspect a locked toolbox even though not
    specifically authorized to do so). W e need not decide if N ew M exico’s regulatory
    scheme authorized the actual opening of boxes, because we agree with the district
    court that on the facts in this record, Officer Smid had probable cause to inspect
    the non-conforming packages for contraband after permissibly entering the trailer
    to inspect the cargo, blocking and bracing.
    II. Adm ission of Evidence
    W e review the district court’s admission of evidence for an abuse of
    -9-
    discretion. United States v. Resendiz-Patino, 
    420 F.3d 1177
    , 1181 (10th Cir.
    2005), cert. denied, 
    126 S.Ct. 1098
     (2006); United States v. Jones, 
    44 F.3d 860
    ,
    873 (10th Cir. 1995). If the trial court erroneously admitted evidence, we need
    not reverse a conviction if the error w as harmless. Resendiz-Patino, 
    420 F.3d at 1181
    ; F ED . R. C RIM . P. 52(a). To determine whether the erroneous admission of
    evidence was harmless, we review the record de novo to determine whether the
    evidence had a “‘substantial influence’ on the outcome or leaves one in ‘grave
    doubt’ as to whether it had such an effect.” United States v. Wacker, 
    72 F.3d 1453
    , 1473 (10th Cir. 1995) (quoting Kotteakos v. United States, 
    328 U.S. 750
    ,
    765 (1946)).
    Rule 803(6) of the Federal Rules of Evidence provides an exception to the
    hearsay rule for business records if they are “kept in the course of a regularly
    conducted business activity, and if it was the regular practice of that business
    activity to make the memorandum [record].” 8 “The rationale behind the business
    8
    Rule 803provides in relevant part:
    The following are not excluded by the hearsay rule . . . :
    (6) Records of Regularly Conducted Activity. - A memorandum,
    report, record, or data compilation, in any form, of acts, events,
    conditions, opinions, or diagnoses, made at or near the time by, or from
    information transmitted by, a person with knowledge, if kept in the
    course of a regularly conducted business activity, and if it was the
    regular practice of that business activity to make the memorandum,
    report, record, or data compilation, all as shown by the testimony of the
    custodian or other qualified witness, unless the source of the
    -10-
    records exception is that such documents have a high degree of reliability because
    businesses have incentives to keep accurate records.” Timberlake Const. Co. v.
    U.S. Fidelity & Guar. Co., 
    71 F.3d 335
    , 341 (10th Cir. 1995). 9 To satisfy Rule
    803(6), “a document must (1) have been prepared in the normal course of
    business; (2) have been made at or near the time of the events it records; . . . (3)
    be based on the personal knowledge of the entrant or of an informant who had a
    business duty to transmit the information to the entrant;” and (4) not have
    involved sources, methods, or circumstances indicating a lack of trustw orthiness.

    370 F.3d 1014
    , 1017 (10th Cir. 2004) (quotation

    for its admission. See United States v. Samaniego, 
    187 F.3d 1222
    , 1224 (10th

    information or the method or circumstances of preparation indicate a

    (“The business records exception is based on a presumption of accuracy, accorded
    because the information is part of a regularly conducted activity, kept by those
    trained in the habits of precision, and customarily checked for correctness, and
    because of the accuracy demanded in the conduct of the nation’s business.”).

    anticipation of litigation is not acting in the regular course of business.”
    Timberlake Const. Co., 
    71 F.3d at 342
    . M oreover, business records are
    potentially fraught with double hearsay. See, e.g., TK-7 Corp. v. Estate of
    Barbouti, 
    993 F.2d 722
    , 729 (10th Cir. 1993). “Double hearsay in the context of
    a business record exists w hen the record is prepared by an employee with
    information supplied by another person.” Wilson v. Zapata Off-Shore Co., 
    939 F.2d 260
    , 271 (10th Cir. 1991). Any information provided by another person, if
    an outsider to the business preparing the record, must itself fall within a hearsay
    exception to be admissible. 
    Id.
    In this case, Exhibit 55 contained two documents: a subpoena issued by
    Special Agent Ivar H ella of the D rug Enforcement Agency, and W estern Union’s
    Response to the subpoena. The district court admitted Exhibit 55 during Special
    Agent Hella’s testimony, reasoning:
    as the case agent and the one who conducted the investigation, he can
    testify as to the contents of the results of his investigation in terms of
    issuing the subpoena. If there’s a foundation laid under 803(6) on
    these subpoenas that they are treated as business records of the DEA,
    then I’m going to allow - it’s not a business record of W estern Union
    because he can’t lay that foundation. But the agent can lay a
    foundation about the way DEA records and keeps its documents, and
    since it’s a response to a DEA subpoena and part of the investigation,
    I think it would be a business record of DEA.
    (R. Supp. Vol. II at 339-40 (emphasis added).) Gwathney does not challenge the
    district court’s determination as to the DEA subpoena, but rather argues Exhibit
    -12-
    55 as a whole was inadmissible on this record because it contained hearsay
    statements of W estern Union. W e agree.
    W estern Union’s response to the DEA’s subpoena is a separate document from
    the subpoena itself and constitutes hearsay. See F ED . R. E VID . 801(c) (“‘Hearsay’ is a
    statement, other than one made by the declarant while testifying at the trial or
    hearing, offered in evidence to prove the truth of the matter asserted.”); United States
    v. Kim, 
    595 F.2d 755
    , 762 (D.C. Cir. 1979) (bank’s response to a subpoena was
    inadmissible hearsay). As such, the response must fall within its own exception to
    the hearsay rule to be admissible. See F ED . R. E VID . 802; Wilson, 939 F.2d at 271.
    Contrary to the district court’s reasoning, the D EA cannot claim W estern Union’s
    response as one of its own business records for the simple reason the DEA did not
    prepare the document. The fact W estern Union’s response is likely trustworthy given
    that it was “required to comply with the terms of the subpoena” does not change this
    basic fact. (Appellee’s B r. at 35); accord United States v. M cIntyre, 
    997 F.2d 687
    ,
    700 (10th Cir. 1993) (holding hearsay imbedded in a business record may be
    admissible only where information is trustworthy, such as where the preparer of the
    document checked the accuracy of the information). If the government wanted to
    pursue such an argument, it could have tried under the residual exception in Rule
    807, 10 but it w as not raised.
    10
    Rule 807 provides in part:
    -13-
    If the W estern Union document was to be admitted as a business record under
    Rule 803(6), it would have to be admitted as a business record of W estern Union. 11
    As the district court correctly noted, Special Agent Hella could not lay a foundation
    for the W estern Union’s response. Absent a proper foundation and applicable hearsay
    exception, it was error to admit W estern Union’s response to the DEA subpoena.
    The error, however, was harmless. The premise of Gwathney’s defense was
    that he w as unaw are of the presence of the marijuana in his trailer. Had the jury
    believed him, he w ould have been acquitted. The evidence regarding the w ire
    transfer (later determined to be $921) went to at least part of the source of the
    $14,000 in cash, not its existence. Nor did it directly address Gwathney’s knowledge
    of the drugs contained in his trailer. Assuming the information contained in W estern
    A statement not specifically covered by R ule 803 or 804 but having
    equivalent circumstantial guarantees of trustworthiness, is not excluded
    by the hearsay rule, if the court determines that (A ) the statement is
    offered as evidence of a material fact; (B) the statement is more
    probative on the point for which it is offered than any other evidence
    which the proponent can procure through reasonable efforts; and (C) the
    general purposes of these rules and the interests of justice will best be
    served by admission of the statement into evidence.

    W e note, however, the difficulty of establishing W estern Union’s
    response to the subpoena as a business record even if a proper foundation were
    laid. From all appearances, the document was prepared in advance of litigation
    and was not regularly produced by W estern Union. See Kim, 
    595 F.2d at 761-62
    (holding bank record was inadmissible under Rule 803(6) because, inter alia, it
    was generated in response to a government subpoena).

    Union’s wire transfer receipt would not have been presented to the jury otherwise, the
    jury could have either believed Gwathney’s testimony that Shaw wired him the money
    for his repairs, or rejected his explanation. Assuming Gwathney received money from
    Shaw, the owner of the truck, the jury could have inferred the money was unrelated to
    the criminal activity or that Gwathney and Shaw were working in concert to smuggle
    drugs. In any event, neither alternative eliminates the possibility that Gwathney knew
    the drugs were in the back of his truck. See Resendiz-Patino, 
    420 F.3d at 1181-82
    (discussing inferences possibly drawn from improperly admitted evidence and holding
    it harmless where no inference eliminated the possibility of guilt). Error that
    undermines the defendant’s credibility as to a tangential issue is harmless and in this
    case harmless beyond doubt. Gwathney’s credibility may have been eroded by the
    improper evidence, but barely. The evidence fairly screams of his knowledge of the
    drugs secreted in his trailer. By comparison, his denials seem bankrupt.
    III. Jury Instructions
    W e review a district court’s decision to give a particular jury instruction for an
    abuse of discretion and consider the instructions as a whole de novo to determine
    whether they accurately informed the jury of the governing law. United States v.
    Soussi, 
    316 F.3d 1095
    , 1106 (10th Cir. 2002).
    The jury instruction at issue, Instruction 13, is a permissive instruction because
    it tells the jury it may, but is not required to, draw an inference about Gwathney’s
    knowledge of the marijuana stored in his truck based on his operation of the vehicle.
    -15-
    See County Court of Ulster County, N.Y. v. Allen, 
    442 U.S. 140
    , 159 (1979); United
    States v. Cota-M eza, 
    367 F.3d 1218
    , 1221 (10th Cir.), cert. denied, 
    543 U.S. 876
    (2004). A permissive inference instruction does not violate a defendant’s Sixth
    Amendment rights provided there is a rational connection between the facts proved by
    the prosecution and the ultimate fact presumed, and the inferred fact is more likely
    than not to flow from the proven facts. Cota-M eza, 
    367 F.3d at 1221-22
    . W e
    evaluate the likelihood in the context of the specific case in which the instruction was
    given. 
    Id. at 1222
    .
    In this case, Gwathney was the sole operator of the trailer containing the drugs.
    Although he did not load the trailer, the load was not sealed by the packers, and
    Gwathney signed the bill of lading. The shoe prints and crushed boxes leading to
    contraband may have suggested that someone placed the boxes containing 335 pounds
    of marijuana in the truck after the potato pallets had been loaded and while it was
    under Gwathney’s control. Based on the evidence, that someone might well have
    been Gwathney, the operator and custodian of the vehicle and the load, or someone
    acting at his behest or with his knowledge. On the other hand, it is possible, in flight
    of fancy, to think someone at the loading site, or persons unknown, surreptitiously
    laced the spuds with marijuana hoping it would somehow find its way to the right
    destination 2000 miles away without the knowledge or complicity of the driver. But
    the jury was not required to infer from Gwathney’s unique position that he had
    knowledge of the 335 pounds of marijuana in his trailer. It was simply permitted to
    -16-
    draw the most likely inferences from available evidence. The high value of the
    marijuana might also, and legitimately, lead a jury to consider it less likely the drugs
    would be transported without the driver’s knowledge. See Cota-M eza, 
    367 F.3d at 1222
    . Our precedent allows a jury to infer the driver of the vehicle has knowledge of
    drugs contained within it. See United States v. Badilla, 
    383 F.3d 1137
     (10th Cir.
    2004), overruled on other grounds by Badilla v. United States, 
    543 U.S. 1098
     (2005)
    (applying United States v. Booker, 
    543 U.S. 220
     (2005)), cert. denied, 
    126 S.Ct. 1344
    (2005); Cota-M eza, 
    367 F.3d at 1222
    ; United States v. Levario, 
    877 F.2d 1483
    , 1485-
    86 (10th Cir. 1989), overruled on other grounds by Gozlon-Peretz v. United States,
    
    498 U.S. 395
     (1991). On these facts, Gwathney’s custody and control of the truck
    and trailer fully justifies the permissive instruction given by the court. Certainly, the
    court did not abuse its discretion by giving Jury Instruction 13.
    IV. M otion for a New Trial
    Gwathney filed a motion for a new trial based on his post-trial discovery of a
    W estern Union record showing he had received $921 by wire transfer from Solomon
    Shaw on M ay 14, 2004. The district court denied the motion. Gwathney challenges
    its ruling on appeal.
    Rule 33 of the Federal Rules of Criminal Procedure authorizes district courts to
    grant new trials “if required in the interest of justice.” A motion for a new trial based
    on newly discovered evidence is generally disfavored and “should be granted only
    with great caution.” United States v. Combs, 
    267 F.3d 1167
    , 1176 (10th Cir. 2001)
    -17-
    (quotation omitted). To procure a new trial based on newly discovered evidence not
    involving a Brady violation, 12 the defendant must show:
    (1) the evidence was discovered after trial; (2) the failure to learn of the
    evidence was not caused by his own lack of diligence; (3) the new
    evidence is not merely impeaching; (4) the new evidence is material to
    the principal issues involved; and (5) the new evidence is of such a
    nature that in a new trial it would probably produce an acquittal.
    United States v. Sinclair, 
    109 F.3d 1527
    , 1531 (10th Cir. 1997) (quotation omitted).
    W e review the denial of a motion for a new trial under the abuse of discretion
    standard. United States v. Quintanilla, 
    193 F.3d 1139
    , 1146 (10th Cir. 1999). “A
    decision is an abuse of discretion only if it is arbitrary, capricious, whimsical, or
    manifestly unreasonable.” Combs, 
    267 F.3d at 1176
     (quotation omitted).
    There is no dispute in this case that the evidence at issue was discovered after
    trial thus meeting Sinclair’s first factor. In our judgment, however, Gwathney failed
    to meet the second factor. It is likely Gwathney’s failure to learn of the existence of
    a wire transfer receipt from Solomon Shaw was caused by a lack of diligence.
    Gwathney, as the recipient of the wire transfer, was certainly in the best position to
    know of the document’s existence and to request it prior to trial. He claims he “had
    no reason to know that discovery of W estern Union records of the wire transfer w ould
    12
    See Brady v. M aryland, 
    373 U.S. 83
    , 87 (1963). The five part test to
    procure a new trial based on newly discovered evidence is not applicable when a
    Brady violation has occurred. United States v. Robinson, 
    39 F.3d 1115
    , 1119
    (10th Cir. 1994); see also United States v. Lopez, 
    372 F.3d 1207
    , 1210 (10th Cir.
    2004) (conducting new trial analysis for Brady violations).

    be required” until the government produced its “surprise” rebuttal testimony.
    (Appellant’s Br. at 24.) Yet Gwathney was aware prior to trial of the irregular
    $14,000 cash payment. He could have anticipated the source of the cash would be
    relevant at trial and sought to obtain supporting documents he knew existed. Nor
    should the introduction of supporting documents in rebuttal have surprised Gwathney.
    It was Gwathney who offered Shaw as the source of the cash at trial, without any
    documentation in support of his contention. See Sinclair, 
    109 F.3d at 1531
     (holding
    the defendant could have reasonably anticipated the relevance of certain documents,
    which remained constant throughout the trial, and sought to obtain them before trial).
    The district court also found the new evidence to be of an impeaching nature
    thus failing Sinclair’s third factor. W e agree. Impeachment evidence is evidence that
    underm ines the credibility of a witness. Gwathney concedes he presented the new -
    found W estern Union receipt “in the form of impeachment evidence,” but argues its
    effect “was to rehabilitate Defendant’s credibility.” (Reply Br. at 12.) W e are not
    persuaded by this distinction. Impeachment evidence offered by a defendant will
    almost always have the effect of rehabilitating his credibility, or at least bolstering his
    theory of the case.
    Even if we were to accept Gwathney’s characterization of the evidence,
    however, we agree with the district court that it was not “material to the principal
    issues involved” in the case. Sinclair, 
    109 F.3d at 1531
    . At best, the wire receipt
    may support Gwathney’s credibility as to a tangential issue — i.e., the source of some
    -19-
    of the money used for the repairs — but we are hard pressed to see how it effectively
    does so. He received a $921 wire transfer, but paid $14,000 in cash for the repairs.
    In any event that evidence is silent as to the principal issue of the case — Gwathney’s
    knowledge of the presence of drugs in his truck. See United States v. Toro-Pelaez,
    
    107 F.3d 819
     (10th Cir. 1997) (“Although [the wire transfer record] would be relevant
    to whether a person named Jorge wired [the defendant] funds, it does not speak to the
    question central to the trial: whether [the defendant] knew that he was transporting
    200 kilograms of cocaine.”). A bstract bolstering of credibility does not bear directly
    on the principal issue of the case — knowledge of the drugs. Gwathney’s argument
    that he had no reason to anticipate the necessity of discovering the wire transfer
    receipt in advance of trial only confirms this conclusion. W e therefore cannot say the
    jury would have reached a different verdict had it heard the new evidence.
    Consequently, the district court did not err in denying Gwathney’s motion for a new
    trial.
