Energy Secretary Rick Perry plans to leave his post in the Trump administration by December, according to The Washington Post and The New York Times.

No formal announcement has been made. “While the Beltway media has breathlessly reported on rumors of Secretary Perry’s departure for months, he is still the Secretary of Energy and a proud member of President Trump’s Cabinet. One day the media will be right. Today is not that day,” Energy Department spokeswoman Shaylyn Hynes told CNN.

In an administration with high turnover, Perry is among one of the longest serving Cabinet members who has remained on the job since the start of Donald Trump’s presidency. He was confirmed as energy secretary on March 2, 2017, with a 62-37 vote in the Senate. The former Texas governor, who has largely kept a low profile throughout his tenure, will likely return to the private sector in the energy industry, two people close to Perry told the New York Times.
