Washington (CNN) President Donald Trump announced Friday that he plans to nominate Deputy Energy Secretary Dan Brouillette to replace Secretary of Energy Rick Perry.

"Dan's experience in the sector is unparalleled," Trump wrote on Twitter Friday. "A total professional, I have no doubt that Dan will do a great job!"

Perry said on Thursday that he plans to leave his post later this year after he informed Trump of his intention to resign.

Trump also praised the current secretary, thanking Perry for "the outstanding job he has done." The President said on Thursday that he had already picked Perry's replacement, and that Perry had been involved in choosing his successor.

Brouillette has been serving as the No. 2 in the Energy Department since he was confirmed to the role in August 7, 2017. As deputy, he has been behind the department's work on "reviving and revitalizing the nuclear industry" and is supportive of the Trump administration's backing of oil and gas industries.
