The FBI and Justice Department public integrity prosecutors in New York City and Washington, D.C. are investigating accusations that Santos lied in his campaign finance filings, among other allegations.
"George Santos needs to resign or be immediately expelled from the House."
Last December, Nassau County, New York District Attorney Anne T. Donnelly—a Republican—also announced that her office was investigating Santos, then a congressman-elect, over his myriad lies.
"The numerous fabrications and inconsistencies associated with Congressman-elect Santos are nothing short of stunning," Donnelly said at the time.
From intrigue surrounding how his net worth skyrocketed from almost nothing to $11 million in less than two years; to demonstrable lies about his education, employment history, residence, and purported Jewish heritage; to allegations of fraud perpetrated in Brazil and against a U.S. combat veteran and his dying dog, Santos' lies have dominated his short congressional career.
While he has admitted to lying about his life, Santos has denied any criminal wrongdoing. Earlier this year, he vowed to serve out his term despite growing calls for him to resign—including from Republican officials in his own district.
Those calls mounted anew following news of Santos' impending indictment.
"We are waiting to see the charges, but we all knew this was where things were heading," said Rep. Nicole Maliotakis (R-N.Y.).
"The sooner he leaves," she added in reference to Santos, "the sooner we can win the seat with someone who isn't a liar."
Rep. Robert Garcia (D-Calif.)—who three months ago introduced a resolution to expel the congressman that more than 40 Democratic lawmakers endorsed—tweeted that "George Santos needs to resign or be immediately expelled from the House."
"Today's news that federal prosecutors are filing criminal charges against George Santos makes it crystal clear that we must act," he added.
