Supreme Court Justice Samuel Alito is warning students that "support for freedom of speech is declining" -- especially on American college campuses. 

Alito made the remark over the weekend during a commencement speech at the Franciscan University of Steubenville in Ohio. Anti-Israel protests have been rocking college campuses nationwide. 

"Right now in the world outside this beautiful campus, troubled waters are slamming against some of our most fundamental principles. Support for freedom of speech is declining, dangerously," Alito said Saturday. "Especially where it should find broadest and widest acceptance." 

"In a book called The Idea of a University, St. John Henry Newman saw the university as a place for reason to debate. Today, very few colleges live up to that ideal," he continued. "This place is one of the few that does and you are very fortunate to have had that experience."
