Nancy Marks, the former campaign treasurer of Rep. George Santos, is set to appear in federal court Thursday afternoon to plead guilty to unspecified charges related to the criminal case against the congressman. Santos was indicted in May on 13 counts, including seven counts of wire fraud, three counts of money laundering, one count of theft of public funds, and two counts of making materially false statements. Marks was responsible for signing off on Santos' expenses related to the 2022 election, and it is unclear what specific charges she faces. It remains to be seen how Marks' plea will affect the outcome of the case against Santos.
