Donald Trump’s labor secretary Lori Chavez-DeRemer is stepping down, the administration announced on Monday, after a series of misconduct allegations including having an affair with a subordinate and drinking on the job.

“Labor Secretary Lori Chavez-DeRemer will be leaving the Administration to take a position in the private sector,” Steven Cheung, a Trump spokesperson, wrote on social media. “She has done a phenomenal job in her role by protecting American workers, enacting fair labor practices, and helping Americans gain additional skills to improve their lives.”

Chavez-DeRemer is the third cabinet member – all women – to depart during the president’s second term, following homeland security secretary Kristi Noem and attorney general Pam Bondi. She wrote on the X social media platform: “It has been an honor and a privilege to serve in this historic Administration and work for the greatest President of my lifetime.”

But Chavez-DeRemer’s exit comes after she became entangled in a string of political and personal controversies. The labor secretary and her close aides are currently under investigation by the department’s inspector general over allegations of professional misconduct.
