Englewood, Colorado-based Liberty Media Corp. announced in a Securities and Exchange Commission filing Tuesday that a longtime partner at Baker Botts has been made its new chief legal officer.

Renee Wilm’s first day as Liberty Media’s chief legal officer was Monday, according to the SEC filing. She replaces Rich Baer who served as the chief legal officer at Liberty Media since 2013. Baer left the company this week to become the chief legal officer at Airbnb Inc. as the company prepares to go public. Baer had also served as Liberty Media’s chief administrative officer since July.
