A private Pennsylvania college says it has expelled three students over a school radio broadcast in which they made racist comments and used a slur.

Bucknell University president John Bravman (BRAHV'-mehn) met with about 1,000 students and staff Tuesday, a day after sending an email to the university community informing them of the expulsions.

He says the March 20 broadcast violated university standards.

Bravman didn't identify the students but shared their comments in "the interest of transparency." He says one used the N-word, a second said "black people should be dead" and the third said "lynch 'em."

The school says an inmate at a nearby prison told a prisoner advocacy group about the comments. The group then contacted a faculty member.

Bucknell is a liberal arts school in Lewisburg, about 50 miles north of Harrisburg.
