CNN Chief Executive Officer Chris Licht has stepped down from the cable news channel after a brief and tumultuous year at the company.

The move marks a swift downfall for Licht, a longtime television executive who in 2022 replaced CNN’s well-liked leader, Jeff Zucker, after he failed to disclose a consensual relationship with a longtime co-worker.

Licht’s departure is immediate and the company will look for a replacement, CNN’s parent company Warner Bros. Discovery Inc. said in a statement.

“I have great respect for Chris, personally and professionally,” said David Zaslav, president and CEO of Warner Bros. Discovery, in the statement. “The job of leading CNN was never going to be easy, especially at a time of huge disruption and transformation, and he has poured his heart and soul into it.

Licht, a former executive producer of “CBS This Morning” and “The Late Show with Stephen Colbert,” arrived at CNN with the goal of creating a less divisive network. CNN had taken a combative stance during the Trump era, and Licht wanted the network to be less opinionated.

But Licht struggled in his first year. One of his first moves was shutting down the CNN+ streaming service just a few weeks after its launch. With Warner Bros. cutting costs, Licht oversaw layoffs of hundreds of CNN employees.

In May, Licht faced a backlash after hosting a town-hall event with former President Donald Trump. The event was widely criticized, including by CNN anchor Christiane Amanpour, for a format that allowed the former president to spread misinformation and talk over the moderator, Kaitlan Collins. A few weeks later, the Atlantic published an embarrassing profile of him in which he criticized the network’s pandemic coverage and appeared aloof to his staff. Following the article, Licht apologized to CNN employees for becoming a distraction and said he’d “fight like hell” to win back their trust.

In early June, David Leavy, a longtime lieutenant of Zaslav, was named CNN’s chief operating officer. While Leavy would run the business side of the network, Licht could focus on CNN’s programming, which had not been going as planned. Most notably, Licht’s new morning show was thrown into turmoil after he fired one of the co-hosts, the controversial longtime CNN anchor Don Lemon.

Meanwhile, CNN’s ratings continued to decline. The network has fallen to third place in the cable news ratings, behind both Fox News and MSNBC.
