The University Of North Carolina at Chapel Hill is facing some heat over how it's treating a Christian fraternity.

Alpha Iota Omega refused to sign on to an anti-discrimination clause on a university application because the fraternity only chooses members who agree with its religious beliefs.

As a result, the university pulled its official recognition of the fraternity, cutting access to student fee money and campus facilities.

Now, a national civil liberties organization is accusing the university of denying the students freedom of religion. But Chancellor James Moeser isn't budging. He says the school is bound by the constitution to ban discrimination.

Moeser is a former vice-president for academic affairs and provost at the University of South Carolina.
