Jim Acosta, CNN anchor and former White House correspondent, announced he's leaving the network on Tuesday. Why it matters: Acosta's departure comes after a nearly 20-year run at CNN, where he notably grilled President Trump during his first administration and was subsequently critical of how he interacted with the media.

The network is moving Wolf Blitzer, a well-known CNN anchor, into his time slot, along with a co-anchor, Pamela Brown. Mr. Acosta’s show is third place in his time slot for total viewers, behind both MSNBC and Fox News, though he has outperformed his MSNBC competitor in the key demographic for advertisers.

Acosta, who frequently clashed with Trump in his first term, is leaving CNN after being stripped of his morning show and offered a midnight program in its place.
