George Santos, the 34-year-old New York Republican who has confessed to lying about part of his background, was sworn into the House of Representatives on Jan. 7 amid several investigations into his campaign and calls for him to resign. Santos was elected in November to represent New York’s 3rd Congressional District covering a part of Queens and Long Island’s North Shore.

Santos has faced intense scrutiny after The New York Times published a report indicating that much of his résumé appeared to have been manufactured, including claims that he owned numerous properties, was previously employed by Goldman Sachs and Citigroup, and had graduated from Baruch College. The report also raised questions about how Santos was able to lend his 2022 campaign $700,000 after having claimed on a campaign finance form in 2020 that he was making $55,000 a year.

And despite presenting himself as Jewish during his congressional campaign, Santos told the New York Post that he never claimed to be Jewish. “I am Catholic,” he said. “Because I learned my maternal family had a Jewish background, I said I was ‘Jew-ish,’” he added. During the campaign, Santos claimed his grandparents were Holocaust survivors, that his mother was in the World Trade Center on 9/11, and that he had employees at the Pulse nightclub when it was attacked.

Santos is now under investigation by the Nassau County district attorney, the New York State district attorney, and federal prosecutors in New York.
