During the Center for a New American Security's annual conference, Biden spoke about the openly hostile environment that some candidates -- he didn't name names -- are creating for Muslims this campaign season.
"There are 1.4 billion Muslims in the world," Biden said. "Some of the rhetoric I'm hearing sounds designed to radicalize all 1.4 billion."
He also criticized Trump's foreign policy positions, as well as his stance on Russia, which Biden said would "call into question America's longstanding commitment to a Europe whole, free and at peace."
