The short answer is: Nothing. At least in Washington, D.C.

The story in New York is different.

Federal and local prosecutors are investigating whether his multiple lies broke any laws. Anne Donnelly, the local prosecutor in Nassau County, where he was elected, is a Republican, and she too has opened an investigation.

The New York Times, which broke the original story, reported last night:

Federal and local prosecutors are investigating whether Representative-elect George Santos committed any crimes involving his finances and lies about his background on the campaign trail.

Federal prosecutors in Brooklyn have opened an investigation into Mr. Santos that is focused at least in part on his financial dealings, according to a person familiar with the matter. The investigation was said to be in its early stages.

In a separate inquiry, the Nassau County, N.Y., district attorney’s office said it was looking into the “numerous fabrications and inconsistencies associated with Congressman-elect Santos” during his successful 2022 campaign to represent parts of Long Island and Queens.

It was unclear how far the Nassau County inquiry had progressed, but the district attorney, Anne Donnelly, said in a statement that Mr. Santos’s fabrications “are nothing short of stunning.”

Why are the Republicans in Congress silent?

Charlie Sykes, who used to be a conservative Republican, writes in The Bulwark that Kevin McCarthy needs Santos’ vote. End of story. His colleagues are saying “He’s learned his lesson,” although he remains defiant. Santos says “Everyone embellishes his resume.” But the proper word is not “embellish,” it’s “lie.” The Congressman-elect lied about his education, lied about his employment, lied about his religion, lied about his family. What part of his resume is true? No one knows.

Probably none of it except his name.

Sykes writes:

Of course, a political party with any sort of intact immune system would move quickly to send this sociopath back to ScamLand, whence he came.

But this is the GOP circa 2022, and so it faces a painful dilemma. With a narrow majority in the House, Republicans (and especially Kevin McCarthy) need his vote, of course.

But that’s not the real problem here, is it?

After years of ignoring, enabling, and rationalizing Big Lies and small ones, it will now be exceedingly difficult for the GOP to find their misplaced conscience that might morph into outrage and something like a moral standard. As Nick Catoggio writes:

Anyone willing to set aside their qualms about Trump for the sake of holding executive power logically should be willing to set aside their qualms about Santos for the sake of holding legislative power

So, not surprisingly, GOP leaders are either silent, or in a forgiving mood.
