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.

Jim Acosta, former Knoxville TV news reporter and anchor, has left his longtime job at CNN. Acosta, who worked at Knoxville's NBC affiliate WBIR from 1995 to 1998, was a prominent face of CNN until his sudden departure this week. He was known for holding President Donald Trump to account.

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.
