George Santos waves after leaving court as he pleads not guilty to new fraud charges

George Santos has pleaded not guilty to revised charges 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 Republican appeared at a Long Island courthouse, where a lawyer entered the plea on his behalf.

Santos previously pleaded not guilty to other charges, first filed in May, accusing him of lying to Congress about his wealth, receiving unemployment benefits he didn't deserve, and using campaign contributions to pay for personal expenses like designer clothing.

The court appearance came the morning after some of Santos' Republican colleagues from New York launched an effort to expel him from Congress.

Santos didn’t speak to reporters as he left the courthouse, but smiled and waved at a small group of protesters shouting insults from across the street.

A judge tentatively scheduled a trial for September, which would come after the state's congressional primary. U.S. District Judge Joanna Seybert turned down a request by prosecutors to have the trial as soon as May.

Santos is 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".

Recently, she told a judge when pleading 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.

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

On Thursday US Rep. Anthony D'Esposito, who represents a congressional district next to the one that elected Santos, introduced a resolution calling for him to be expelled from the House.

He argued Santos wasn't fit to serve his constituents. He was joined by four other New York Republicans - U.S. Reps. Nick LaLota, Michael Lawler, Marc Molinaro and Brandon Williams.

Santos posted a cryptic note on X, formerly Twitter, writing: "Everything has an end in life."

But in a later post, he added three points of clarification: "1. I have not cleared out my office. 2. I’m not resigning. 3. I’m entitled to due process and not a predetermined outcome as some are seeking."

The New York Republican has previously said he intends to run for re-election next year, but could face a lengthy prison term if convicted.
