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.

CNN anchor Jim Acosta, who rose to acclaim as a hard-charging reporter who frequently clashed with members of the first Trump administration, said Tuesday that he will be leaving the network he has worked at since 2007.
