evidence: His statement that he was a professor in college left many wondering when — or even if — Biden was ever a professor. Biden has taught constitutional law as an adjunct professor and worked at the University of Pennsylvania after his time as vice president. [...] Some, unaware about his time teaching law, believe Biden is being misleading when he says he was a professor, pointing to his time at the University of Pennsylvania. It is true, according to the University of Pennsylvania’s own newspaper, The Daily Pennsylvanian, that Biden has never taught a class at that university. However, he does hold an honorary professor position, according to The Daily Pennsylvanian. After finishing his eight-year stint as the vice president of the United States, Biden was chosen to be Penn’s Benjamin Franklin Presidential Practice Professor and he was also named the "driving force" behind the university’s Penn Biden Center for Diplomacy and Engagement.
