Former FBI Director James Comey’s convocation address at Howard University on Friday was interrupted repeatedly by student chants and protests.

Comey joined the faculty of Howard in a part-time capacity this fall, filling the Gwendolyn S. and Colbert I. King Endowed Chair in Public Policy. He is expected to deliver a series of five lectures in that position over the course of the year.

But on Friday, Comey was shouted over by the students he was addressing. As Comey began his speech to the Howard class of 2021, some students burst into a chorus of black civil rights anthem “We Shall Not Be Moved.”

The singing students rose in one section, fists raised in the air in a sign of solidarity. They then proceeded to chanting, including phrases like “I love being black” and “no justice, no peace, no racist police.”
