U.S. Rep. George Santos is set to be arraigned Friday on a revised indictment accusing him of several frauds, including making tens of thousands of dollars in unauthorized charges on credit cards belonging to some of his campaign donors.

The New York Republican was scheduled to appear at a courthouse on Long Island to enter a plea to the new allegations. He has already pleaded not guilty to other charges, first filed in May, accusing him of lying to Congress about his wealth, applying for and receiving unemployment benefits, even though he had a job, and using campaign contributions to pay for personal expenses like designer clothing.

Santos has been free on bail while he awaits trial. He has denied any serious wrongdoing and blamed irregularities in his government regulatory filings on his former campaign treasurer, Nancy Marks, who he claims “went rogue.”
