A former CNN producer has called out Jim Acosta for giving "all good journalists a bad name" after he heckled President Trump during remarks about the five journalists who lost their lives in Thursday's deadly newsroom attack in Annapolis, Maryland. 

"This attack shocked the conscience of our nation and filled our hearts with grief. Journalists, like all Americans, should be free from the fear of being violently attacked while doing their job," President Trump said.

This prompted CNN's Jim Acosta to start heckling Trump – asking the President "Will you stop calling the press the enemy of the people?"

A man in front of Acosta is visibly annoyed, turning around several times to shush the CNN employee.
