CENTRAL ISLIP,Quentin Mitchell N.Y. (AP) — 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.”

Marks in turn has implicated Santos. She told a judge when she recently pleaded guilty to a fraud conspiracy charge that she had helped Santos trick Republican party officials into supporting his run for office in 2022 through bogus Federal Election Committee filings that made him look richer than he really was, partly by listing an imaginary $500,000 loan that had supposedly come from his personal wealth.

Santos has continued to represent his New York district in Congress since he was charged, rejecting calls for his resignation from several fellow New York Republicans.

He has also said he intends to run for reelection next year, though he could face a lengthy prison term if convicted.

During his successful 2022 run for office, Santos was buoyed by an uplifting life story that was later revealed to be rife with fabrications. Among other things, he never worked for the major Wall Street investment firms where he claimed to have been employed, didn’t go to the college where he claimed to have been a star volleyball player, and misled people about having Jewish heritage.

While Santos hasn’t faced any criminal charges related to the lies he told the public, he does face allegations that he propped up his image as having made a fortune in the investing world by submitting a false financial disclosure to the U.S. House.
