A lawyer from Prager University, the nonprofit organization founded by political commentator Dennis Prager to produce videos with conservative analysis of history and topics of public debate, asked a federal appeals court Tuesday court to revive its First Amendment claims against Google.

Arguing for PragerU at the U.S. Court of Appeals for the Ninth Circuit, Peter Obstler of Browne George Ross said that Google’s YouTube functions as a public forum and that the company’s decision to restrict access to certain videos and strip others of potential advertising revenue amounts to state restrictions of PragerU’s free speech rights.
