evidence: In a speech to service members and first responders on the anniversary of the terrorist attacks of September 11, 2001, President Joe Biden falsely claimed that he was at Ground Zero the day after the Twin Towers fell in Manhattan. [...] Facts First: Biden was not at Ground Zero the day after 9/11. He actually went to Ground Zero nine days after the attacks. Asked Monday night about the claim, the White House provided a photo and article showing that Biden, then a senator for Delaware, toured Ground Zero on September 20, 2001. A White House official then emailed this comment on condition of anonymity: "The President first visited the World Trade Center nine days after the September 11 terrorist attacks as part of a bipartisan delegation from the Senate."
