The president of Oberlin college says that the Ohio college is making "significant progress" investigating a series of hate speech crimes on campus during Black History Month. The college, known widely as a place that's liberal and forward-thinking, canceled classes on Monday in order to hold a series of rallies to help unify students. The incidents in question included a "whites only" being written above a water fountain and a swastika scrawled across a science center window, according to the college newspaper the Oberlin Review. The paper also reported a series of physical assaults on campus in which the assailant made derogatory remarks about a student's ethnicity.

"We have made significant progress in the investigation of these instances." "We believe these actions represent the work of a very small number of very cowardly people," he told a packed audience of 1,200 students. "I am shocked that this happened at our college, which I love. It hurts all of us."
