While appearing on the "Late Show with David Letterman" in 2007, Biden was asked what it felt like to walk into the Senate chamber after having been elected as a 29-year-old to become freshman senator from Delaware.
Biden said he had already walked on the Senate floor.
"I walked in when I was 21 and I got arrested," Biden told Letterman. "It was a Saturday. I was down visiting some friends at Georgetown University, and I came up on a Saturday morning because I was fascinated with the Senate, and they had a Saturday session.
"I walked up. Those days, no guards stopping you everywhere, and they just got out of session. I walked in the back, all of a sudden, I found myself in the chamber and I was stunned. I walked up, sat down [in] the presiding officer's seat. A guy grabbed me by the shoulder and said, 'You're under arrest.'"
A few years later, Biden walked into the chamber to take the chair he got by defeating incumbent J. Caleb Boggs, R-Del.
"As I walked onto the Senate floor through the same door, that same guy, cop, said to me, 'Senator, you remember me?'" Biden said on the show. "I said, 'Geez, I don't.' He said, 'I arrested you nine years ago.' He said, 'Welcome back.'"
The trespassing arrest must’ve taken place in 1962 or 1963, well before modern-day terrorism and the decay of social trust in US society ordered comprehensive security restrictions in buildings such as the US Capitol. Biden didn’t face charges after his trespassing arrest. If he had tried such a thing in this century, he’d almost guaranteed face greater scrutiny, although the Democratic Party is famous for its double standards regarding criminal riots.
Biden has little to no grounds to demand aggressive prosecution of people who walked into the Capitol building and walked around aimlessly, considering he confessed to doing as such himself without facing any consequences.
There was no evidence Biden was arrested for trespassing. Biden's appearance on Letterman's show remains available on social media.
The president also once insisted he had been arrested while trying to visit Nelson Mandela in South Africa during the apartheid era. However, he later backtracked by saying he meant he was "not able to move," per Fox News.
The clip of Biden on Letterman's show has appeared on social media after protesters trespassed and violently rioted at the Capitol on Jan. 6.
