On Monday, CNN's Jim Acosta tweeted out a snarky response to White House Press Secretary Sarah Sanders' decision not to call on him for the third consecutive briefing. He was quickly shot down by her response.

As Monday's press briefing came to an end and Sanders started walking out of the room, Acosta shouted at her: "Sarah, can I ask a question? Sarah, that's the third briefing you've not taken a question from CNN. Do you expect the Justice Department to enforce all subpoenas, Sarah?"

Frustrated by her lack of response, Acosta tweeted: "Third press briefing in a row that @PressSec did not take a question from CNN. #courage."

Sanders did not ignore Acosta's tweet as she quickly fired back: "Courage isn’t taking “a question from CNN,” Jim. Courage is combat veterans Sgt. Peck and Staff Sgt. Dwyer - the two heroes at the briefing. #itsnotaboutyou"
