Per the president, Perry's departing by the end of the year.
Brouillette has also embraced Trump's call for US dominance of worldwide energy markets and says he backs an "all of the above" policy that promotes nuclear and renewable solar and wind energy as well as coal, natural gas and oil. On Thursday, he notified President Trump that his intention was to leave his job soon, according to two White House administration sources.
"Even if the inquiry was validly authorised, much of the information sought in the subpoena appears to consist of confidential Executive Branch communications that are potentially protected by executive privilege", said the letter, a copy of which was obtained by Reuters.
A Louisiana native, Brouillette worked at the Energy Department under former President George W. Bush as an assistant secretary for congressional and intergovernmental affairs. But like Perry, Brouillette has an easy relationship with many Democratic and Republican politicans, McMonigle said. Perry did not state specifically what day he will be leaving the administration. Members of Congress are investigating whether the White House withheld military aid to the country or offered a White House summit on the condition Ukrainian officials investigate former Vice President Joe Biden and his son, Hunter. There's a lot of money and corruption in the gas business in Ukraine, and most people I talk with say Perry was a force for trying to Westernize the gas business there, to open the markets and get rid of the corruption.
U.S. Energy Secretary Rick Perry stated his intention to resign was not connected with the scandal about the phone conversation between Presidents of the United States of America and Ukraine. "I never heard that said anywhere, anytime in any conversation". "So it was a right time for me to come back home", he said in the interview.
House Democrats had also sought documents related to Perry's trip to Ukraine for President Volodymyr Zelensky's inauguration, when Perry led the USA delegation in place of Vice President Mike Pence at Trump's instruction.
The deputy has been taking on increasingly high-profile roles for Perry, including sitting in for him at cabinet meetings.
He served as chief of staff to the House Committee on Energy and Commerce and is also a US Army veteran from San Antonio.
