TikTok CEO Kevin Mayer, who only began the job on June 1, is heading right back out the door again as the company plans a sale under pressure from the White House.

“In recent weeks, as the political environment has sharply changed, I have done significant reflection on what the corporate structural changes will require, and what it means for the global role I signed up for,” Mayer wrote in an email to TikTok employees late Wednesday. “Against this backdrop, and as we expect to reach a resolution very soon, it is with a heavy heart that I wanted to let you all know that I have decided to leave the company.”

Mayer praised employees’ efforts, saying that “there is no doubt that the future [of TikTok] is incredibly bright.” But at the same time, he added, “I understand that the role that I signed up for—including running TikTok globally—will look very different as a result of the US Administration’s action to push for a sell off of the US business.”
