    BERNICE BOUIE DONALD, Circuit Judge. After a jury trial, Arthur Rathburn was
    convicted of seven counts of wire fraud, in violation of 
    18 U.S.C. § 1343
     and one count of illegal
    transportation of hazardous material, in violation of 
    49 U.S.C. § 46312.1
     Specifically, the
    government charged Rathburn with renting out human bodies and body parts that tested positive
    for HIV and hepatitis B to unsuspecting medical professionals. Rathburn was also charged with
    transporting a diseased human head overseas and back to the United States without proper
    packaging or labeling, in violation of federal law. The district court sentenced Rathburn to
    108 months’ imprisonment.      Rathburn appeals his convictions, raising several challenges,

    Rathburn was also indicted on two additional counts of wire fraud and two counts of
    making false statements in violation of

    these charges.

    I.
    BACKGROUND
    Rathburn owned and operated International Biological, Inc. (“IBI”), a Michigan
    corporation, until 2013 when it was raided by the FBI and Rathburn and his then wife, Elizabeth
    Rathburn, were indicted on charges of wire fraud. IBI supplied human cadavers and other
    anatomical specimens to medical professionals for training purposes.           Elizabeth Rathburn2
    managed IBI and primarily interacted with its customers. Rathburn obtained donated cadavers
    and body parts (“specimens”) from two Chicago-based companies, Anatomical Services, Inc
    (“ASI”) and Biological Resource Center of Illinois (“BRCIL”), who obtained their specimens from
    the Arizona-based Biological Resource Center (“BRC”).3
    Each specimen came accompanied by a donor information sheet and a serology report,
    which indicated whether the specimen tested positive for certain infectious diseases, such as HIV
    and hepatitis B and C viruses. Once IBI received the specimen and report, Rathburn would store
    the specimen in IBI’s warehouse to rent to medical professionals for medical or dental training
    courses.
    Particularly important here, Rathburn drafted, and directed employees to provide IBI
    customers, a Material Request Form (“MRF”) and Service Agreement (collectively, “contracts”).
    The MRF read, in pertinent part: “All anatomical materials are . . . tested for HIV and hepatitis A,
    2
    Elizabeth Rathburn divorced Rathburn prior to trial.
    3
    After discovering that ASI and BRC obtained their supply of infectious specimens from
    BRCIL, Rathburn sought to cut out the middle-man and do business with BRC directly, but BRC
    refused. BRC’s business was shut down and Stephen Gore, a principal in BRC, was charged in
    Arizona state court of violating the wishes of donors and supplying infected remains.
    -2-
    Case No. 18-1652, United States v. Rathburn
    B and C.” The MRF provided for further testing “upon request at an additional charge.” The
    Service Agreement stated, in part:
    Unless expressly set forth on MRF, the anatomical materials to be provided
    hereunder will have been screened for HIV ½, Surface Antigen, Hepatitis B and
    Hepatitis C Virus Antibody and shall accordingly be treated by service user and its
    research participants as if such materials may be infectious. Service provider
    expressly disclaims any liability should any anatomical material prove infectious.
    (emphasis added).
    Rathburn provided identical contracts containing this provision to all IBI customers.
    Elizabeth Rathburn testified that the “goal” of this language was to “assure the customer that they
    were getting a clean body to work on.” Despite these explicit assurances, Rathburn obtained
    specimens that tested positive for infectious diseases for discounted prices and supplied them to
    IBI customers, while concealing the positive test results. According to Elizabeth Rathburn,
    Rathburn did not disclose positive results “[b]ecause the customer wouldn’t have accepted the
    specimen and IBI would have lost the contract.” Instead, she testified that Rathburn believed that
    by embalming the specimens, it would “yield the virus inactive.”
    Dr. Samuel Lee, a periodontist, testified that IBI supplied a human head for a March 2011
    dental-implant training course that he led for Harvard University. Unbeknownst to Dr. Lee, the
    head that IBI provided tested positive for hepatitis B. Dr. Lee testified that he believed the
    language in the contracts—that the specimen would be “screened” and “tested” for hepatis B—
    meant that IBI would not intentionally provide him with a “specimen that [was] infected with
    [hepatitis B].” Though Dr. Lee testified that he used “universal precautions” despite Rathburn’s
    assurances, he nonetheless would have “prefer[red] not to use a cadaver that tested positive for
    hepatitis B” and would have declined IBI’s services had Rathburn disclosed the positive results.
    Similarly, Dr. Kevin Vorenkamp, an anesthesiologist and director of the American Society
    of Anesthesiologist’s (“ASA”) pain workshop, obtained a cadaver from IBI for use in a training
    -3-
    Case No. 18-1652, United States v. Rathburn
    conference in October 2012. The serology report obtained by Rathburn revealed that the specimen
    tested positive for HIV and hepatitis B.4           Rathburn supplied the infectious specimen to
    Dr. Vorenkamp as well without disclosing the positive test results. Rathburn also provided
    Dr. Vorenkamp with a cadaveric demographic sheet that falsely indicated the specimen “tested
    negative for HIV, hepatitis.”
    Like Dr. Lee, Dr. Vorenkamp understood the language in the contracts to mean that IBI
    would screen and test the specimens for HIV and hepatitis B, and that the ASA “would not get a
    body that tested positive.” Although he, too, used universal precautions, Dr. Vorenkamp testified
    that he would not have knowingly received a specimen that tested positive for HIV and hepatitis
    B “out of concern for cutting into [infected] bodies.”
    The MRF also provided that all specimens would be procured under “clean, not sterile
    conditions.” According to FBI Special Agent Leslie Larsen, Rathburn’s facility was all but clean.
    Agent Larsen testified that upon entering Rathburn’s warehouse, she observed, among other
    things: “upwards of 10 to 20” piles of dead flies and other insects; “dirt and dust . . . caked” on the
    floor; multiple specimens “frozen together . . . flesh-to-flesh,” with no barriers to prevent cross
    contamination, and dried blood splattered across the floor.
    Elizabeth Rathburn confirmed that the conditions observed by Agent Larsen were
    consistent with the daily conditions of IBI’s warehouse during the times the IBI provided
    specimens to Doctors Lee and Vorenkamp in 2011 and 2012.5 Both doctors testified that they
    4
    Due to the infected status of the specimen, Rathburn received a credit in the amount of
    $3,500.
    5
    Elizabeth Rathburn further testified that Rathburn often stored specimens in such a manner
    that they froze together and Rathburn would need to use a crowbar to separate.
    -4-
    Case No. 18-1652, United States v. Rathburn
    would not have paid IBI for the specimens had they known Rathburn procured them under
    unsanitary conditions.
    The government also charged Rathburn with illegally transporting hazardous material,
    stemming from his shipment of eight human heads from Tel Aviv to Detroit, Michigan, one of
    which came from a donor whose cause of death was “bacterial sepsis and bacterial pneumonia.”
    Although Stephen Gore with BRC testified that Rathburn was provided a burial transit form
    revealing the donor’s cause of death as bacterial sepsis, Rathburn shipped the infected specimen
    to Tel Aviv for an overseas training course, and back to Detroit, Michigan in only a trash bag
    placed inside a camping cooler.
    Prior to trial, Rathburn attempted to introduce evidence that, although the specimens tested
    positive for infectious diseases at the time of death, they were not actually infectious at the time
    of the courses.6 The government sought to exclude this evidence, arguing that the case was about
    whether Rathburn intentionally misled IBI customers into believing he would not intentionally
    provide them with specimens that tested positive for infectious diseases, not whether the specimens
    were actually infectious at the time of the course. The district court reserved its ruling for trial, at
    which time it agreed with the government and excluded evidence relating to whether the specimens
    were infected at the time of the courses. The district court reasoned:
    We’re not talking about transporting diseases to the world. We’re talking about the
    charge in the indictment where the fraud is that they made a contract, they violated
    that by sending diseased parts, and that’s the story. Whether someone at a
    conference could have caught the disease, we’re not going to go into that.
    6
    In his motion for acquittal, Rathburn presented an email from Dr. Carl Schmidt opining
    that it was “unlikely” that the specimens were infectious at the time of the courses because: “(1) the
    lab reports were negative; (2) anatomical preservation liquids, such as formalin and the embalming
    fluids are toxic and tend to inactivate almost all infectious agents; and (3) the time lapse since
    death would have inactivated about anything that had serious infective potential.”
    -5-
    Case No. 18-1652, United States v. Rathburn
    At the close of his case, Rathburn moved for judgment of acquittal on all counts, pursuant
    to Rule 29 of the Federal Rules of Criminal Procedure, which the district court denied.
    Rathburn timely appeals and raises the following challenges: (1) the government presented
    insufficient evidence to support his convictions; (2) 
    49 U.S.C. § 46312
     is unconstitutionally vague
    because it fails to give fair notice of what constitutes an infectious substance; (3) the district court
    denied him his right of confrontation; (4) the district court allowed inadmissible evidence by
    permitting witnesses to testify about what they believed the contracts meant, in violation of
    Michigan law; (5) the district court’s failure to give jury instructions regarding alternate
    interpretations of the service agreement under Michigan law violated his due process rights; and
    (6) the graphic photos shown to the jury were unfairly prejudicial.
    II.
    ANALYSIS
    1. Sufficiency of the Evidence for Wire Fraud
    Rathburn first argues that there was insufficient evidence to support his convictions of wire
    fraud. To succeed in challenging the sufficiency of the evidence, Rathburn must demonstrate that,
    “after viewing the evidence in the light most favorable to the prosecution, [no] rational trier of fact
    could have found the essential elements of the crime beyond a reasonable doubt.” United States
    v. Clark, 
    928 F.2d 733
    , 736 (6th Cir. 1991) (quoting Jackson v. Virginia, 
    443 U.S. 307
    , 319
    (1979)). “A defendant bringing such a challenge bears a ‘very heavy burden.’” United States v.
    Daniel, 
    329 F.3d 480
    , 485 (6th Cir. 2003) (quoting United States v. Vannerson, 
    786 F.2d 221
    , 225
    (6th Cir. 1986)).
    Wire fraud requires the government to prove three elements: “(1) a scheme or artifice to
    defraud; (2) use of interstate wire communications in furtherance of the scheme; and (3) intent to
    -6-
    Case No. 18-1652, United States v. Rathburn
    deprive a victim of money or property.” Id. at 485 (citation and internal quotations omitted).
    Rathburn contends the government failed to establish the first and third elements.
    With regard to the first element, Rathburn avers the government failed to establish that he
    made a material misrepresentation because the contract only “provided for screening” of HIV and
    hepatitis B and C, which Rathburn contends was satisfied. According to Rathburn, agreeing to
    screen specimens is “[f]ar from a contractual promise of a disease-free specimen.” Thus, he
    contends there was insufficient evidence to sustain his conviction. We disagree.
    We have recognized that a scheme to defraud requires “sufficient evidence of several
    misrepresentations,” and “includes any plan or course of action by which someone intends to . . .
    deprive another by deception of money or property by means of false or fraudulent pretenses,
    representations, or promises.” Daniel, 
    329 F.3d at 485
     (quoting United States v. Gold Unlimited,
    Inc., 
    177 F.3d 472
    , 479 (6th Cir. 1999)). A scheme to defraud is not measured by a “technical
    standard,” but rather is a “reflection of moral uprightness, of fundamental honesty, fair play and
    right dealing in the general and business life of members of society.” United States v. Van Dyke,
    
    605 F.2d 220
    , 225 (6th Cir. 1979) (citation and internal quotation marks omitted).
    Applying this standard, the government presented sufficient evidence that Rathburn
    intended to defraud IBI customers into believing he would not supply them with specimens that
    tested positive for infectious diseases. First, the ordinary understanding of a promise to “test” and
    “screen” for HIV and hepatitis creates a reasonable understanding that IBI would not supply
    specimens in spite of a positive result. In addition to its common-sense understanding, Elizabeth
    Rathburn testified that Rathburn purposefully provided this language in the contracts to “assure
    the customer that they were getting a clean body.” Rathburn’s intent to deceive is further
    evidenced by the donor information sheet that he provided to Dr. Vorenkamp, explicitly indicating
    -7-
    Case No. 18-1652, United States v. Rathburn
    that the specimen “tested negative for HIV, hepatitis,” when Rathburn knew that was false. This
    was sufficient evidence for a rational trier of fact to find that Rathburn acted with the intent to
    defraud customers.
    Rathburn’s misrepresentations were indeed material. A statement is materially false “if it
    has a natural tendency to influence, or [is] capable of influencing, the [decision-maker].” Neder
    v. United States, 
    527 U.S. 1
    , 16 (1999). Doctors Lee and Korenkamp testified that they believed
    that by promising to “screen” and “test” the specimen, Rathburn would not intentionally provide
    them with infectious specimens and that they would have rejected the specimens had they known
    of the positive results. Moreover, Elizabeth Rathburn’s testimony that Rathburn did not disclose
    positive results “[b]ecause the customer wouldn’t have accepted the specimen and IBI would have
    lost the contract” further signals Rathburn’s knowledge of the materiality of the contract language.
    Relying on the following language in the Service Agreement: “[IBI] disclaims any liability
    should any anatomical material prove infectious,” Rathburn contends this language demonstrates
    that “there were no guarantees that the specimen would not be infected.” This argument falls flat.
    That the contracts did not provide a “guarantee” that the specimens would never be infected does
    little to counter Rathburn’s indication that diseased specimens would be screened out and not
    intentionally provided to customers.
    The third element of wire fraud requires that “the misrepresentation or omission must have
    the purpose of inducing the victim of the fraud to part with property or undertake some action that
    he would not otherwise do absent the misrepresentation or omission.” United States v. DeSantis,
    
    134 F.3d 760
    , 764 (6th Cir. 1998). Rathburn contends there was insufficient evidence to establish
    that he intended to deprive IBI customers of money because his failure to disclose the screening
    results “was of no real consequence.” As support, Rathburn relies on the following: (1) the
    -8-
    Case No. 18-1652, United States v. Rathburn
    agreement explicitly warned customers that the “specimens could be infected,” and to use
    “universal precautions;” and (2) the “the course[s] [were] a success,” therefore the customers
    “suffered no financial harm.” This is all beside the point.
    Indeed, the Service Agreement provided cautionary language expressly limiting liability in
    the event a specimen proved infectious. However, providing a specimen that “could” theoretically
    prove infectious despite being screened is a far cry from providing specimens that are “known” to
    have tested positive for infectious diseases. Rathburn appears to suggest that, because the doctors
    used universal precautions, they did not rely on the misrepresentations made in the contracts. What
    Rathburn overlooks is that “reliance is not one of the two elements of wire fraud.” United States
    v. Griffith, 
    17 F.3d 865
    , 875 (6th Cir. 1994) (citation omitted). Thus, that IBI customers used
    universal precautions despite Rathburn’s assurance that the specimens would be screened for
    certain infectious diseases is not relevant.
    Moreover, whether the course was ultimately successful is likewise immaterial to a wire
    fraud analysis. See United States v. Merklinger, 
    16 F.3d 670
    , 678 (6th Cir. 1994) (“[T]he mail and
    wire fraud statutes do not require proof that the intended victim was actually defrauded; the actual
    success of a scheme to defraud is not an element.” (citation omitted)). What is relevant, however,
    is whether Rathburn made misrepresentations intending to get IBI customers to pay money for
    specimens that they otherwise would not have. See Daniel, 
    329 F.3d at 487
     (“It is sufficient that
    the defendant by material misrepresentations intends the victim to accept a substantial risk that
    otherwise would not have been taken.”).
    The record demonstrates sufficiently that the doctors would not have paid Rathburn for the
    specimens but for his representations that they would be screened for infectious diseases.
    Elizabeth Rathburn testified that if IBI customers knew of the positive results, they “wouldn’t have
    -9-
    Case No. 18-1652, United States v. Rathburn
    accepted the specimen.” Doctors Lee and Vorenkamp both confirmed that they depended on the
    language in the contracts as assurance that the specimens had been screened that they would not
    have paid IBI for the specimen had Rathburn disclosed the positive results. This was sufficient
    for a jury to determine that Rathburn intended to deprive IBI customers of money. Rathburn fails
    to meet his “heavy burden” of showing that “[no] rational trier of fact could have found the
    essential elements of” wire fraud. 7 
    Id. at 485
    ; Clark, 
    928 F.2d at 736
    .
    2. Sufficiency of the Evidence for Illegal Transportation
    of Hazardous Material & Vagueness
    Rathburn raises two challenges with respect to his conviction for illegally transporting
    hazardous material, in violation of 
    49 U.S.C. § 46312
    : (1) the statute is unconstitutionally vague,
    and (2) there was insufficient evidence to sustain his conviction. We address both below.8
    Vagueness. We review de novo whether a criminal statute is unconstitutionally vague.
    United States v. Namey, 
    364 F.3d 843
    , 844 (6th Cir. 2004) (citation omitted). To demonstrate that
    § 46312 is unconstitutionally vague, Rathburn must show that it “fails to provide a person of
    ordinary intelligence fair notice of what is prohibited, or is so standardless that it authorizes or
    7
    Rathburn also contends that, because the FBI raid occurred in 2013, a year after the
    relevant courses were conducted, there was insufficient evidence to establish that the warehouse
    was not clean during the relevant time periods. This claim likewise fails. Elizabeth Rathburn
    testified that the condition of the warehouse, as depicted in the photographs taken by the FBI, were
    consistent with its daily conditions in 2011 and 2012. This, too, was sufficient for a jury to find
    intent to defraud.
    8
    Relying on Fed. R. Crim. P. 12(b)(3)(A), the government contends Rathburn waived his
    vagueness argument because he failed to raise it pretrial. However:
    Fed. R. Crim. P. 12(b)(2) provides that “Lack of jurisdiction or the failure of the
    indictment or information to charge an offense shall be noticed by the court at any
    time during the pendency of the proceeding.” The defense of failure of an
    indictment to charge an offense includes the claim that the statute apparently
    creating the offense is unconstitutional.
    United States v. Seuss, 
    474 F.2d 385
    , 387 n.2 (1st Cir. 1973). Thus, this objection may be raised
    at any time. 
    Id.
    - 10 -
    Case No. 18-1652, United States v. Rathburn
    encourages seriously discriminatory enforcement.”       F.C.C. v. Fox Television Stations, Inc.,
    
    567 U.S. 239
    , 253 (2012) (citation and internal quotation marks omitted).
    Rathburn contends he was not provided fair notice of what conduct the statute prhibted
    because the statute’s “clear purpose” of preventing the transportation of “infectious” substances is
    contradicted by the Department of Transportation’s (“DOT”) definitional expansion to include
    material “known or reasonably expected” to be an infectious substance. Rathburn’s claim, while
    couched as a vagueness argument, more accurately challenges the DOT’s authority to define
    infectious substances under the statute. Where Congress empowers an agency to promulgate rules
    and regulations necessary to carry out an Act, we must uphold those regulations “so long as it is
    reasonably related to the purposes of the enabling legislation.” Jackson v. Richards Med. Co., 
    961 F.2d 575
    , 581 (6th Cir. 1992) (citation and internal quotation marks omitted).
    The relevant statute, § 46312(a)(1), makes it a federal offense to “deliver[]” or “cause[] to
    be delivered” hazardous materials to an air carrier for shipment. By explicit delegation, Congress
    authorized the DOT to designate as hazardous any material that “may pose an unreasonable risk
    to health and safety or property.” 49 U.S.C.A. § § 5102, 5103. In line with this directive, the DOT
    defines an infectious substance as “a material known or reasonably expected to contain a
    pathogen.” 
    49 C.F.R. § 173.134
    . The DOT defines a pathogen as “a microorganism . . . including
    bacteria [or] viruses . . . that can cause disease in humans or animals.” § 173.134(a)(1). It is
    indisputable that the question of what an infectious substance is “has been duly delegated to the
    [DOT], with its expertise, to [answer].” Chrysler Corp. v. Dep't of Transp., 
    472 F.2d 659
    , 675
    (6th Cir. 1972). Rathburn fails to demonstrate how the DOT’s definition of infectious substance
    runs contrary to § 46312(a)(1)’s purpose. That Rathburn would prefer that substances “reasonably
    - 11 -
    Case No. 18-1652, United States v. Rathburn
    expected” to contain an infectious substance not come within the purview of the statute is
    insufficient to challenge its constitutionality. This argument fails.
    Sufficiency of the evidence. Rathburn’s sufficiency of the evidence challenge fairs no
    better. At trial, the government charged Rathburn with transporting via air carrier a human head
    that was obtained from a body whose cause of death was “bacterial sepsis and bacterial
    pneumonia”—both Category B Biological Substances under § 46312. See C.F.R. § 173.134.
    Category B infectious substances are defined as substances not generally capable of causing “life-
    threatening or fatal disease in otherwise healthy humans or animals when exposure to it occurs.”
    Id. As relevant here, prior to shipping a Category B infectious substance, it “must be packaged in
    a triple packaging consisting of a primary receptable, a secondary packaging, and a rigid outer
    packaging.” C.F.R. § 173.199(a)(1)–(3). The primary receptacles must be packed “in such a way
    that, under normal conditions of transport, they cannot break, be punctured, or leak their contents
    into the secondary packaging.” § 173.199(a)(2). Finally, the wording “Biological substances,
    Category B” must be marked on the outer packaging, with UN337 in contrasting color.
    § 173.199(a)(5). Knowledge of the regulations is “not an element of an offense . . . but shall be
    considered in mitigation.” 
    49 U.S.C. § 46312
    .
    Rathburn does not dispute that the specimen he shipped overseas and back to the United
    States was not packaged in accordance with the DOT regulations. Nor does he dispute that the
    package failed to include the required Category B labeling.9 Instead, Rathburn contends that the
    9
    Though Rathburn argues that the infectious status has been neutralized at the time of
    shipment, Mark Razny with DOT testified that a specimen maintains its designation as a Category
    B substance until it is either cremated or autoclaved, neither of which Rathburn did prior to
    shipment. In any event, whether the specimen was infectious at the time of shipment is
    inconsequential to the relevant question under the DOT regulations of whether it was “known or
    reasonably expected” to be an infectious substance. 
    49 C.F.R. § 173.134
    .
    - 12 -
    Case No. 18-1652, United States v. Rathburn
    donor summary provided by BRC indicated the cause of death as “Parkinson’s disease” and
    “pelvic fracture.” But the government provided contrasting testimony from Stephen Gore, who
    testified that the burial transit form that accompanied the specimen when it was sent from BRC,
    indicated the donor’s cause of death as “bacterial sepsis and bacterial pneumonia.” Viewing this
    conflicting evidence in favor of the government, a reasonable trier of fact could conclude that
    Rathburn was aware of the donor’s cause of death when he shipped the specimen without proper
    packaging or labeling. See United States v. Tilton, 
    714 F.2d 642
    , 645 (6th Cir. 1983) (“[A]n
    appellate court must view all the evidence in the light most favorable to the government, resolve
    all inferences which may reasonably be drawn from the evidence in the government’s favor and
    resolve all conflicts in the testimony in the same way.”) (citation omitted). Therefore, Rathburn’s
    sufficiency of the evidence challenge fails,
    3. Confrontation Clause
    Next, Rathburn asserts the district court denied him his right to confrontation by allowing
    the government to introduce evidence to suggest that the specimens were likely infected, but failed
    to permit him to cross-examine and present evidence to demonstrate that the specimens were not
    actually infected.   We review de novo “[e]videntiary rulings relating to violations of the
    Confrontation Clause.” United States v. Henderson, 
    626 F. 3d 326
    , 333 (6th Cir. 2010) (citation
    omitted). The Confrontation Clause guarantees the right of an accused in a criminal prosecution
    “to be confronted with the witnesses against him.” Delaware v. Van Arsdall, 
    475 U.S. 673
    , 678
    (1986). The Confrontation Clause does not prohibit a trial judge from imposing reasonable limits
    on cross-examination based on concerns about confusion of the issues. See 
    id.
    Rathburn asserts that the district court denied him his right of confrontation by permitting
    the government to elicit testimony “that [IBI customers] would have rejected the human remains
    . . . because they feared infection,” but refused to allow Rathburn to elicit cross-examination or
    - 13 -
    Case No. 18-1652, United States v. Rathburn
    present evidence to show the specimens were not infectious at the time of the courses. We disagree
    with Rathburn.      The district court proscribed Rathburn from presenting evidence or cross-
    examining witnesses about whether the specimens were infectious at the time of the courses,
    reasoning that their infectiousness during the courses was irrelevant to whether Rathburn
    intentionally defrauded customers and would unnecessarily confuse the jury.
    We find the district court’s limitation reasonable for two reasons. First, the Confrontation
    Clause “does not bar the use of testimonial statements for purposes other than establishing the truth
    of the matter asserted.”    Crawford v. Washington, 
    541 U.S. 36
    , 59 (2004).             None of the
    government’s witnesses testified that the specimens were infectious at that time of the courses.
    Although the doctors called by the government did testify that they would have rejected specimens
    that tested positive for an infectious disease out of general fear related to the spread of infection,
    this demonstrated the reason the doctors prefer disease-free specimens. But why the doctors would
    have rejected specimens known to have tested positive for infectious diseases goes to the
    materiality of Rathburn’s misrepresentations—not to the truth of whether the specimens were
    actually infectious at the time of the courses. Thus, Rathburn’s inability to cross-examine
    witnesses about whether the specimens were infectious during the courses did not violate his right
    to confrontation.
    Second, as an element of wire fraud, the government charged that Rathburn intentionally
    deprived IBI customers of money by misleading them into believing he would not knowingly
    supply them specimens that tested positive for infectious diseases. Whether the specimens were
    infectious at the time of the courses is insignificant to the relevant inquiry of whether Rathburn
    obtained money by falsely representing that he would screen against certain infections. See United
    States v. Phillips, 
    872 F.3d 803
    , 809 (6th Cir. 2017) (“District courts retain wide latitude insofar
    - 14 -
    Case No. 18-1652, United States v. Rathburn
    as the Confrontation Clause is concerned to impose reasonable limits on . . . interrogation that is
    repetitive or only marginally relevant.”) (internal quotation marks omitted) (quoting Van Arsdall,
    
    475 U.S. at 679
    ). Importantly, Rathburn was permitted to present evidence and cross-examine
    witnesses with respect to whether the specimens tested positive for the infectious diseases and
    whether he was aware that they did. This was sufficient for him to defend against the elements of
    wire fraud. See 
    id.
     (“[The Confrontation Clause does not guarantee cross-examination that is
    effective in whatever way, and to whatever extent, the defense might wish.”). The district court
    did not err in limiting evidence and cross-examination related to whether the specimens were
    infectious during the courses.
    Next, Rathburn raises two separate, but related, challenges: (1) the district court admitted
    inadmissible evidence by permitting witnesses to vary and add to the express terms of the contract,
    in violation of Michigan state law; and (2) the district court improperly refused to give jury
    instructions regarding contract interpretation under Michigan law.
    Inadmissible Evidence. We afford the district court “broad discretion on evidentiary
    rulings because this type of decision turns upon the evidence as developed during the course of a
    trial.” United States v. Todd, 
    920 F.2d 399
    , 403 (6th Cir. 1990) (citation omitted). Rathburn
    contends that, because the plain language of the Service Agreement provided only that the
    specimens would be “screened” for certain infectious diseases, the district court was obligated to
    invoke Michigan contract law to bar witness testimony regarding what they “believed the terms”
    meant. Relying on Michigan law, Rathburn argues that the Service Agreement must be “enforced
    as written,” and that “extrinsic evidence cannot be used to very (sic), add or contradict the express
    terms of the contract.” Appellant’s Br. at 37 (citing Henderson v. State Farm Fire and Gas Co.,
    
    460 Mich. 348
    , 354 (1999) and In Re Egbert R. Smith Trust, 
    480 Mich. 19
    , 24 (2008)).
    - 15 -
    Case No. 18-1652, United States v. Rathburn
    Rathburn is mistaken. The government charged Rathburn with wire fraud—not breach of
    contract. The elements of wire fraud are separate and district from Michigan contract law. See
    United States v. Perry, 537 F. App’x 347, 349 (5th Cir. 2013) (recognizing that common law
    contract rules are inapplicable to the crime of wire fraud); see also Daniel, 
    329 F.3d at 486
    (observing that “common law requirements of justifiable reliance and damages . . . have no place
    in the federal fraud statutes”). Rathburn points to no authority to support his contention that
    Michigan contract law should apply in this context.
    Jury Instruction. Rathburn’s contention that the district court improperly refused to give
    jury instructions regarding contract interpretation under Michigan law fails for the same reasons
    above—Michigan contract law is irrelevant to the federal charge of wire fraud. As the district
    court also noted, “[w]hile [Rathburn’s] preference would have been a civil suit charging breach of
    contract” this was not the case before the jury.
    4. Inadmissible Photographs
    Lastly, Rathburn takes issue with several photographs presented to the jury of specimens
    recovered by the FBI during its raid of Rathburn’s warehouse in December 2013 as well as
    photographs depicting the unsanitary conditions of the warehouse. “Evidence may be excluded if
    its probative value is substantially outweighed by the danger of unfair prejudice.” United States
    v. Boyd, 
    640 F.3d 657
    , 667 (6th Cir. 2011) (citing Fed. R. Evid. 403). Moreover, “the admission
    of relevant, potentially prejudicial evidence is placed within the sound discretion of the trial court.”
    United States v. Brady, 
    595 F.2d 359
    , 361 (6th Cir. 1979).
    Rathburn claims that the government’s “deliberate” and “repeated” use of inflammatory
    photographs was “demonstrably prejudicial” and “therefore a new trial is mandated.” The first set
    of photographs that Rathburn challenges depict: an open cooler with several human heads frozen
    together; frozen blood at the bottom of a freezer unit and floor; a human head and torso in a semi-
    - 16 -
    Case No. 18-1652, United States v. Rathburn
    frozen state; dried blood in the bottom of a cooler; and a pile of dead flies on the floor. The
    remaining photographs depict: a human head, a cooler lined with blood, packaging that dripped
    with blood-like fluid, and the outer shipment packaging. The photographs were relevant to the
    government’s charges of wire fraud, illegal transportation of hazardous material, and making
    materially false statements; any prejudice to Rathburn was neither unfair, nor did it substantially
    outweigh the probative value of the evidence.
    With respect to the first set, as Rathburn acknowledges, in addition to charging that
    Rathburn materially misled customers to believe he would not provide specimens that tested
    positive for certain infectious diseases, the government charged Rathburn with intending to
    defraud IBI customers into believing that the specimens were procured under “clean” conditions.
    The government presented these photographs to demonstrate that Rathburn stored specimens flesh-
    to-flesh, without any protective, sanitary barriers to prevent cross-contamination, and that his
    representation that specimens were procured under “clean” conditions was fraudulent. Though
    potentially unpleasant, Rathburn does not demonstrate that the probative value of these
    photographs was substantially outweighed by unfair prejudice. United States v. Hardy, 
    228 F.3d 745
    , 750 (6th Cir. 2000). Indeed, we have recognized that probative “[e]vidence is not unfairly
    prejudicial simply because it is gruesome or disturbing.” Boyd, 
    640 F.3d at
    667–68; see also
    United States v. Mellies, 329 F. App’x. 592, 600 (6th Cir. 2009) (observing that, although photos
    of child pornography, “by its very nature, [are] inherently disturbing,” they were not unfairly
    prejudicial because they were “essential to proving an element of the charged crime” (emphasis
    removed)).
    The next group of photographs that Rathburn challenges relate to his charges of illegal
    transportation and making false statements. The government introduced photographs of the bloody
    - 17 -
    Case No. 18-1652, United States v. Rathburn
    packaging that Rathburn used to ship the specimen into the United States as evidence that Rathburn
    failed to package the specimen according to the DOT regulations because liquid dripped
    throughout the internal packaging. The photographs of the external packaging revealed neither
    blood nor human specimens and were merely relevant to the government’s charge that Rathburn
    failed to properly label the shipment as a Category B substance as required by DOT regulations.10
    Again, Rathburn fails to establish that the probative value of these photographs was substantially
    outweighed unfair prejudice to him.
    The remaining photographs that Rathburn challenges relate to two charges of making
    materially false statements to the FBI, of which he was acquitted. The government sought to
    disprove two statements made by Rathburn: that the human heads he shipped from overseas were
    embalmed, and that the fluid discovered in the bottom of the cooler and dripping from the
    packaging was “Listerine,” and not blood. To disprove the first, the government introduced a
    photograph showing that the human head that Rathburn claimed to have embalmed prior to
    shipment was not in fact embalmed.11 As to Rathburn’s second statement, the government
    introduced a photograph of the shipping package dripping in liquid to disprove Rathburn’s claim
    that the fluid was Listerine instead of blood. These photographs were relevant to each charge
    brought by the government. Rathburn was ultimately acquitted of making false statements. This
    cuts against Rathburn’s claim: that he was acquitted of these charges tends to illustrate that the
    photographs introduced by the government to establish his guilt were not unfairly prejudicial. See
    10
    Rathburn contends that the photographs “were so prejudicial that one juror [indicated] he
    was in need of counseling.” Two reasons demonstrate why this does not amount to prejudice.
    First, this was limited to a single juror and that juror was made an alternate. Second, that the
    photographs were disturbing does not, alone, rise to the level of prejudice. Boyd, 
    640 F.3d at
    667–
    68.
    11
    The government introduced two photographs of the same human head to show that it
    decayed over time—evidence that it was not embalmed.

    United States v. Johnson, 726 F. App’x 393, 401–02 (6th Cir. 2018) (holding that a defendant
    failed to demonstrate prejudice in large part because he was acquitted of the charges where the
    jury would have been most likely to be prejudiced). Rathburn’s evidentiary challenge fails.
    III.
    CONCLUSION
    For these reasons, we affirm Rathburn’s convictions.
