Kevin Tsujihara, the chairman and CEO of Warner Bros. Entertainment is stepping down following an investigation into a relationship he had with actress Charlotte Kirk, and ensuing allegations that he used his position to help her find work. No successor has been named.

Warner is still in the middle of an ongoing investigation on the issue with a third-party law firm and Tsujihara’s cooperation.

“It is in the best interest of WarnerMedia, Warner Bros., our employees and our partners for [Tsujihara] to step down as chairman and CEO of Warner Bros.,” said John Stankey, WarnerMedia’s CEO in a press release. “[Tsujihara] has contributed greatly to the studio’s success over the past 25 years and for that we thank him. [Tsujihara] acknowledges that his mistakes are inconsistent with the company’s leadership expectations and could impact the company’s ability to execute going forward.”

His resignation follows shortly after Tsujihara added the new global kids and young adults business to his remit as part of the WarnerMedia personnel shuffles. After the AT&T-Time Warner merger was completed, he took over the unit, which brings together linear cable nets Cartoon Networks, Adult Swim, Boomerang, Turner Classic Movies, digital content investment venture Otter Media, and anything involving licensed consumer products for WarnerMedia properties.
