Called the “largest COVID-19 fraud scheme in the nation,” U.S. Rep. Virginia Foxx, R-N.C., on Wednesday sent a letter and subpoena to Tim Walz and his state administration associated with the federal child nutrition programs and Feeding Our Future, and to the Biden administration’s U.S. Department of Agriculture and its Office of Inspector General. Walz is Vice President Kamala Harris’s running mate on the Democratic ticket.
