Rep.-elect George Santos admitted to the New York Post Monday that he lied while running for office.

Santos told the publication that he fabricated details about his work experience, education, family history and finances.

The 34-year-old who recently won the election for New York's 3rd District told the New York Post, "My sins here are embellishing my resume. I'm sorry."

According to The New York Post, Santos admitted that he lied about graduating from college and that he never worked for Goldman Sachs and Citigroup.

Santos also told the publication that he is "clearly Catholic" and was married to a woman for about five years. He told The New York Post he is now a happily married gay man.

Those revelations come after he spoke out about his grandparents escaping the Holocaust and fleeing to Brazil.

The admission comes after a New York Times article said much of Santos' resume may not be real.

The fallout from the article led New York state Attorney General Letitia James to launch an investigation into his claim.

Former congressional candidate Robert Zimmerman, who lost to Santos in the election, said his former opponent is not fit to hold public office.

"He actually acknowledged today that he defrauded the voters of the 3rd Congressional District, so while the election can't be overturned, he should in fact resign from taking office," Zimmerman said. "Because he's shown from his lying about his faith, lying about his jobs, lying about his education and admitting to writing bad checks and just disregarding his financial obligations, being a deadbeat tenant that he's not fit to hold public office."

Santos told the New York Post that he is not a criminal and he won't be deterred from having a good legislative session.

News 12 made multiple attempts Monday to contact Santos and his campaign but did not hear back as of 10 p.m.
