Nassau County Republican leaders will call on Rep. George Santos to resign Wednesday for fabricating his biography to win his congressional seat, three people with knowledge of the plans told POLITICO.

« They’ll issue a rebuke of him for running as a complete liar in an effort to resuscitate the image of the party, » said one person familiar with the pending announcement by Nassau County GOP Chair Joe Cairo and other Republican elected officials, speaking on condition of anonymity.

That person told POLITICO in an interview that the announcement is necessary to help Republicans win future elections in New York’s 3rd congressional district, which is a swing seat formerly held by Democrat Tom Suozzi.

Santos has lied about everything from where he went to college to his Jewish ancestry. He’s being investigated by local, state and federal authorities.

The Nassau County GOP will officially make the rebuke at 11:30 a.m Wednesday at its Westbury, N.Y., headquarters. Two other individuals familiar with the announcement confirmed the news to POLITICO.

The same day, Speaker Kevin McCarthy told reporters he wouldn’t sit Santos on any of the so-called « A Committees » — including more powerful panels such as Judiciary, Ways and Means and Budget, which typically don’t go to first-term lawmakers anyway. It’s still unclear if Santos will be seated on committees at all, as some of his GOP colleagues have called to totally exclude him from panel spots.

McCarthy and other House Republican leaders still haven’t publicly signaled how they plan to handle Santos’ fabrications internally.
