evidence: Biden said, "Democracy is at stake, folks. Our democracy is under attack. And we gotta fight for it. I taught at the University of Pennsylvania for four years. And I used to teach political theory. And folks, you always hear every generation has to fight for democracy. And I found myself – it's automatic, we didn't have to believe it – but we do. We do." [...] Conservative digital strategist Greg Price shared the clip to X and commented, "Biden claims he ‘taught political theory’ at the University of Pennsylvania. He never taught a single class at UPenn." [...] As Biden's critics on social media claimed, there is little to no evidence that Biden ever taught "political theory" at the University of Pennsylvania. Though UPenn's website notes that the president was the Benjamin Franklin Presidential Professor of Practice from 2017 to 2021, a Snopes.com fact-check on his previous but similar claim – that he was a "full professor at the University of Pennsylvania" for four years – found that "he did not teach a semester's worth of courses" while in this role.
