Nassau County Republican officials on Wednesday called on newly sworn-in Rep. George Santos, the Republican who confessed to lying about key details of his background, to resign.

«George Santos’ campaign last year was a campaign of deceit, lies and fabrication,» Nassau County Republican Party Chairman Joe Cairo said at a news conference with other party officials.

Cairo took aim at Santos for having «disgraced» the House and made it clear that the freshman congressman «is not welcome here in the Republican headquarters.»

“We don’t consider him one of our congressmen,” Cairo said.

Moments later, Santos told reporters that he would not resign. He ignored further questions from reporters.

The lawsuit comes less than a week after Santos officially took office following the election of Rep. Kevin McCarthy, R-Calif., as Speaker of the House last week. Santos voted for McCarthy.

Nassau County Republican officials initially endorsed Santos in the 2022 election cycle. But after Santos admitted to lying about parts of his resume, including his education and employment history, county Republicans condemned his actions.

«Congressman-elect George Santos has breached public trust by making serious misstatements about his background, experience and education, among other issues,» Cairo said in a statement.
