Former GOP Rep. George Santos is expected to plead guilty on Monday to multiple charges related to campaign finance fraud, less than a month from when his trial was set to begin, two sources familiar with the matter tell NBC News.

The disgraced former lawmaker faces a 23-count superseding indictment in the Eastern District of New York, including charges of wire fraud, aggravated identity theft and making materially false statements to the Federal Election Commission.

The superseding indictment is an addition to a 13-count federal indictment on charges of wire fraud, money laundering and theft of public funds that Santos was hit with in May 2023.
