A law professor at the University of Missouri has filed a lawsuit that challenges the school's gun ban. 

Royce de R. Barondes' lawsuit argues that voters in Missouri approved a constitutional amendment last year that allows people to keep a gun in the passenger compartment of a vehicle. 

But Barondes, who has a concealed-carry permit, is prohibited from bringing his firearm on campus because of the university's ban. 

The professor, who is being represented by one of his former students, Jennifer Bukowsky, talked to Brian Kilmeade this morning on "Fox and Friends."

Eight states - Mississippi, Wisconsin, Kansas, Oregon, Texas, Utah, Colorado and Idaho - allow guns to be carried on public college campuses.

Barondes and Bukowsky said the university should respect state law and the Second Amendment. 

"The right to bear arms is a natural right. It's necessary for our own self-defense and the university doesn't have a right to choose how we defend ourselves. Under the Missouri Constitution and the federal Constitution, as well as state law, my client should be able to possess a firearm in his vehicle and on his person on university-controlled property," said Bukowksy.

She said she's looking forward to the case going to court, arguing that "bad guys" target campuses where they know students and faculty are not armed.

The university has not commented on the lawsuit.
