Congressional Democrats are calling on New York Republican Congressmember-elect George Santos to resign, after he admitted he repeatedly lied about his work, education and family history. On Monday, Santos admitted to the New York Post he fabricated his claims that he’d worked for Goldman Sachs and Citigroup and that he’d earned a degree from Baruch College. Santos also spoke with New York radio station WABC.

Rep.-elect George Santos: “I’m not a fraud. I’m not a criminal who defrauded the entire country and made up this fictitional character and ran for Congress. I’ve been around a long time. I mean, a lot of people know me. They know who I am. They’ve done business dealings with me. And I’m not going to make excuses for this, but a lot of people overstate in their résumés or twist a little bit or aggrandiate themselves. I’m not saying I’m not guilty of that.”

Santos also admitted that he falsely claimed that his grandparents were Jewish and fled the Holocaust. He told the New York Post, “I am Catholic. Because I learned my maternal family had a Jewish background I said I was 'Jew-ish.'” Texas Democratic Representative Joaquin Castro responded that Congress should expel George Santos if he refuses to resign, and called on authorities to investigate him. Castro added, “Just about every aspect of his life appears to be a lie. We’ve seen people fudge their resume but this is total fabrication.”
