Federal prosecutors hit Rep. George Santos, R-N.Y., with 23 additional charges Tuesday, including allegations of identity theft and that he charged a supporter’s credit card in excess of their contribution and then transferred the money to his personal bank account.

In a press release, prosecutors said the scheme included falsely claiming that relatives of Santos and his then-campaign treasurer Nancy Marks had donated big bucks to his campaign to make it appear that he was raising more money than he actually had in order to qualify for assistance from the national party.
