CNN president Jeff Zucker, who helped the news outlet become the dominant name in cable news, intends to leave the media organization at the end of the year.

“This organization has been through a lot. I’d like to be here to get us all back to a new normal, one that feels much more like it once did around here,” Zucker said in a Thursday call with CNN producers that was obtained by Variety. “So, as a result, I am going to stay and finish my current contract — which, as I said, will keep me here until the end of this year. At that point, I do expect to move on.”

It is unclear who will replace Zucker. A representative from CNN parent company WarnerMedia did not return a request for comment.

Zucker, who joined CNN in 2013, helped catapult the outlet to the top of the cable news game during Donald Trump’s presidency.
