A police officer watches over the pro-Palestinian encampment at Drexel University, in Philadelphia, Wednesday, May 22, 2024. University administrators tried to open a line of communication to the protesters but were rebuffed, Drexel President John Fry said in a statement Tuesday. Lecture classes will remain virtual for a third day Wednesday because of the encampment, and some events will have to be rescheduled, Fry said. (Alejandro A. Alvarez/The Philadelphia Inquirer via AP)
