Energy Secretary Rick Perry is being considered to lead the Department of Homeland Security by President Trump after former Marine Gen. John Kelly left the job to become his chief of staff, sources told Bloomberg News on Wednesday.

President Trump named Kelly as his chief of staff on Friday, and is considering other individuals to fill the vacant Cabinet position as well.

"Secretary Perry is focused on the important mission of the Department of Energy," Robert Haus, director of public affairs at the Department of Energy, said to Bloomberg. "He's honored to be mentioned, but he loves what he's doing."

The Department of Energy released a similar statement in a tweet on Wednesday, saying, "While @SecretaryPerry is honored to be mentioned, he is happy where he is and focused on carrying out mission POTUS gave him to lead @ENERGY."

Deputy Secretary of Homeland Security Elaine Duke is currently filling in as acting secretary until the Trump administration finds a new secretary to fill the position.

During his time as secretary of Homeland Security, Kelly supported Trump's mission to build a border wall along the U.S. border with Mexico.

Perry, a former governor of Texas, does not completely align with Trump on immigration. While running for president in 2012, he said Republicans didn't have a "heart" regarding immigrants, although Bloomberg noted he is supportive of further reinforcements along the border.
