CNN parted ways with Chief Executive Chris Licht, a person briefed on the matter said, ending a tenure of a little over a year that was marked by a series of perceived missteps.

Licht stepped down several days after a blistering profile in the Atlantic led to something of an insurrection inside the news network as both on-air talent and producers voiced their growing frustrations and anger over his leadership.

Licht, who was installed as CEO when Warner Bros. Discovery WBD 0.83%increase; green up pointing triangle took control of the network, also had been under fire for some of CNN’s programming decisions, including a recent town hall with former president and current Republican front-runner Donald Trump, whose format was widely criticized.

Since Licht took over, CNN’s ratings have been at historic lows. Licht has been experimenting with new programming to counter the ratings slide, including a new morning show that has struggled to gain traction, and attracted controversy earlier this year when co-host Don Lemon said on the show that Republican presidential candidate Nikki Haley wasn’t in her prime. Lemon has since left the network.
