The gaffe-inclined leader of the free world was talking about abolishing the Senate filibuster on the campus of Clark Atlanta University and Morehouse College on Tuesday when he made a mistake he has done several times before.
Students and faculty listening to his speech at the Atlanta University Center Consortium did not seem to catch the slip-up, and he did not bother to correct himself.
Referencing last year's Capitol Hill riot on January 6, he told the crowd: "Last week, President Harris and I stood in the United States Capitol to observe one of those before and after moments in American history."
Biden has referred to his second-in-command as "President Harris" several times since coming into office - including at a speech in South Carolina last month.

Biden was fast to fix his tongue on Tuesday, making sure to change "damn" to "darn" and "hell" to "heck" - much to the amusement of the crowd, who laughed on both occasions.
When describing how hard he worked on getting Strong Thurmond to vote for extending the Voting Rights Act, he told the crowd: "You have no idea how damn ha- — how darn hard, I worked on that one."

And while citing a new Georgia law that will make it unlawful to deliver drinks or meals to people waiting in line to vote, he said: "What in the hell — heck are we talking about?"

He also seemed to joke about being seized while speaking about the Civil Rights movement.
Biden talked of how he had "walked" certain "grounds", adding: "Seems like yesterday, the first time I got arrested - anyway."
It was not clear what he was referring to but it comes after he had to excuse a claim that he was arrested while trying to see Civil Rights icon, Nelson Mandela.

One of the first moments Biden called Kamala "President Harris" was in March last year, while offering updates on the vaccination program.
"When President Harris and I took ..." Biden said, before taking a moment to pause, "a virtual tour of a vaccination site in Arizona not long ago, one of the nurses on that tour injecting people, giving vax each shot, was like administering a dose of hope."

Vice President Harris was present during the comments, but her reaction was not seen on camera.
Biden resounded the gaffe in December during a gaffe-laden appearance at the South Carolina State University commencement ceremony. He told the crowd: "Of course, President Harris is a proud Howard [University] alum."
And a year earlier, in December 2020, before the Biden Administration was sworn in, Biden called Harris the "President-elect."
