All tickets for the lecture will be voided and information about the rescheduled date will be posted later, the university said in an online post about the postponement. Pre-paid parking will be automatically refunded, the university added.

Additional pro-Palestinian protests took place Tuesday afternoon at the university in front of Coffman Memorial Union. The protests prompted university officials to temporarily close down at least a dozen buildings in a Tuesday alert. Those included: Coffman Union, Weisman Museum, Hasselmo Hall, Ford Hall, Vincent Murphy Hall, Tate Lab, Morrill Hall, Northrop Auditorium, Johnston Hall, Walter Library, Smith Hall, and Kolthoff Hall. All other East Bank campus buildings were switched to keycard access only, according to the alert.
