Rep. George Santos, R-N.Y., admitted to being "a terrible liar" in a candid interview this week, having made numerous false claims about his mother's having been in the Twin Towers on 9/11 and his "Jew-ish" ancestry. Host Piers Morgan grilled Santos about how he thought he could get away with the fabrications, to which Santos responded that he didn't think he'd ever be found out. Questions about Santos' biography have swirled since a New York Times investigation last year, and it remains to be seen if he will be held accountable for his actions.
