evidence: After Sen. Bernie Sanders (I-Vt.) suspended his campaign last week, Joe Biden became the presumptive Democratic nominee. Although he is not a Penn alumnus and has never taught a formal class, the former Vice President has strong ties to the University. But Biden's affiliation with the University has been met with confusion, and most recently scrutiny from right-leaning media outlets who question his recent campaign trail assertion that "rather than "taking a Wall Street job, [he] became a teacher, became a professor" after his term as vice president ended. [...] Although he does not teach regular classes, Biden has appeared on campus several times, and spoken at Penn on at least five occasions. Some of his visits include a dialogue at Irvine Auditorium with former U.K. Deputy Prime Minister Nick Clegg, Penn’s 2018 Silfen Forum, and an event with President Gutmann, where he discussed international relations and cancer research.
