First ladies night, now women's studies

First, attorney Roy Den Hollander fought against ladies' night in New York bars.

Now, he's taking on women's studies.

Hollander is suing Columbia University in federal court, charging the women's studies program is unconstitutional.

The lawsuit claims the college program is discriminatory because there's nothing comparable for men.

No comment yet from Columbia.

Last year, Hollander sued to end ladies' nights at New York nightclubs.

That case is still pending.
