NEW YORK (AP) — X CEO Linda Yaccarino said she’s stepping down after two years running Elon Musk’s social media platform.

Yaccarino led X through a tumultuous period as the social network tried to rebuild its relationship with brands concerned that their ads could show up next to offensive content.

Yaccarino did not provide a reason for her departure, but in an X post, she spoke fondly of the company and X owner Elon Musk.
