evidence: Joe Biden has come under fire after claiming to have visited the ruins of the World Trade Center on September 12, 2001, one day after the 9/11 attacks, despite there being no records of the then-senator being in New York at all that day. [...] While there is no record of Biden being at Ground Zero on September 12, 2001, he did give a speech that day to the Senate, during which he said the attackers had managed to unite the civilized world against them. [...] When contacted for comment by Newsweek, a White House spokesperson noted Biden did visit Ground Zero on September 20, 2001 as part of a Senate delegation, but didn't comment on his claim to have been at the site on September 12.
