Watch: Sean Spicer Tells Anxious Reporter "Calm Down, It's Not Your Press Briefing"

Once again, the White House press briefing became heated on Monday when ABC News’ Jonathan Karl began interrupting the AP’s Julie Pace during her question to Press Secretary Sean Spicer.

Karl objected to Spicer's response to the question regarding Paul Manafort's responsibilities during the 2016 campaign.

“Hey Jonathan, hold on can you stop interrupting other people’s questions? Hey, Jonathan somebody is asking a question. It’s not your press briefing. Julie is asking a question. Please calm down,” Spicer reminded Karl.
