Penn State University's president says an investigation into the Facebook posting of nude photographs by a now-suspended fraternity points to the possible need for a re-evaluation of the entire fraternity system.

Eric Barron issued a statement Wednesday night to the Penn State community, saying some senior university leaders see a need for such a review.

He says, "We are considering our options."

Kappa Delta Rho was recently suspended for a year by its national organization over allegations that members shared frat house photos of nude and partly nude women on a private, invitation-only Facebook page.

It was one of several recent scandals in the U.S. involving fraternities, despite a push to reduce drinking and sexual assault on campuses.

Fraternities, social organizations for male students, have a big influence on life in many campuses.
