“ The question presented in this case is the scope of federal jurisdiction under 18 U.S.C. § 1001, which criminalizes the making of false statements "in any matter within the jurisdiction of any department or agency of the United States." Petitioner was convicted under that statute for making false statements on an application for Georgia state unemployment insurance benefits. The state program is certified by the United States Department of Labor to receive federal funds which are used only for administrative expenses, not for benefits. ”
