CNN has promoted Jim Acosta to Chief White House Correspondent, the network announced  Tuesday. Acosta previously served as the network’s Senior White House Correspondent.

Over the last year, Acosta has become a fixture in the White House briefing room. His often combative exchanges with Trump administration officials have routinely made the rounds on social media and earned the ire of conservative critics — including President Donald Trump.

In one famous exchange from the White House in August, Trump refused to take a question from Acosta and accused him of spreading fake news.

“Mr. President, haven’t you spread a lot of fake news yourself, sir?” Acosta shot back. Trump has also trashed CNN’s ratings to Acosta’s face on live television.
