Energy Secretary Rick Perry on Oct. 17 announced his resignation later this year.

Bloomberg News earlier reported that Perry had informed President Donald Trump of his resignation. During a visit to Texas on Oct. 17, Trump confirmed to reporters that Perry would be resigning and said he would announce a replacement soon.

Perry, who was expected to announce his resignation from the Trump administration by the end of November, was subpoenaed Oct. 10 by House Democrats as part of a congressional impeachment inquiry regarding the president.

Committee on Foreign Affairs Chair Eliot Engel, D-N.Y., Intelligence Committee Chair Adam Schiff, D-Calif., and former Committee on Oversight and Reform Chair Elijah Cummings, D-Md., specifically ordered Perry to produce a variety of Ukraine-related documents by Oct. 18, citing public reports that he participated in White House efforts to pressure Ukraine into interfering in the 2020 U.S. presidential election by denying military aid. Cummings died Oct. 17.

In his resignation letter, Perry told Trump on how the U.S. is now leading the world in energy production, exploration and exports. "From reviving our commercial nuclear energy industry to producing historic levels of domestic oil and gas and renewable energy, America has seen a remarkable turnaround in our energy industry," Perry said.

Perry added that he will be continuing to support the president's agenda after he returns home to Texas.
