NEW BRUNSWICK, N.J. — A growing number of faculty at Rutgers University are calling for additional firings after a video surfaced of the men’s basketball coach shoving and berating players with gay slurs.

Coach Mike Rice was fired Wednesday.

More than 50 faculty have signed a letter calling for the dismissal of athletic director Tim Pernetti. They also want President Robert Barchi to explain why he didn’t fire Rice immediately after learning of the video in December.

Meanwhile, the number of professors signing a separate letter demanding Barchi step down has more than doubled to at least 28. That letter calls the president’s handling of the whole episode “inexcusable.”

The president had initially agreed with a decision to discipline the coach rather than have him let go. But he says he changed his mind after viewing the video this week.

A group of 13 faculty members Wednesday demanded that university President Robert Barchi resign for his “inexcusable handling” of the situation.

Alumni, lawmakers and a gay-rights group are among those calling for an investigation into why university officials took months to fire Rice after getting the video from a former basketball program employee in a scandal that touches on two long-standing issues on campus: the role of sports and the treatment of gays.
