Appellant Morris James was convicted of twenty-three counts of mail fraud, violating 18 U.S.C. § 1341. He raises several issues on appeal. The court has carefully considered appellant’s position in light of the briefs, oral arguments, and pertinent portions of the record. We conclude that, viewing the evidence in the light most favorable to the verdict, there was sufficient evidence to demonstrate specific intent to defraud and thus to sustain James’s convictions. Further, the district court did not abuse its discretion in denying James’s request for subpoenas or an investigator because James failed to make the requisite showing of necessity at trial, and has not demonstrated to this court that the district court’s ruling was prejudicial to his defense. No Batson violation was present in the Government’s use of peremptory challenges. Additionally, the district court did not err in its instruction to the jury concerning a matter of tax law. Finally, we hold that the district court’s admission of evidence at trial did not violate the Sixth Amendment’s confrontation clause. The district court judgment is AFFIRMED.
