Attorney General Jeff Sessions said Tuesday on “Fox & Friends” that he believes there is a bias against conservative speech on college campuses.

“Fox & Friends” co-host Steve Doocy referred to conservative commentator Ben Shapiro’s recent appearance at University of California Berkely as an example of bias on campuses. The event cost $600,000 for security related expenses, and reports leading up the event described how the university was “bracing” for Shapiro. Doocy argued that it hasn’t been all sides whose free speech rights are “suffocated.”

“It is just one side,” that is being suffocated, Doocey said.

“Right. What we see often is the heckler’s veto, we call it,” Sessions responded. “That means that a group of protesters raise a ruckus before a speaker comes. Often the speech is either canceled or put in a secondary location that is not effective.”
