President Donald Trump announced he has fired Gen. Charles Q. Brown Jr., the now-former chairman of the Joint Chiefs of Staff.

The president said he will nominate Air Force Lieutenant General Dan “Razin” Caine to the position, which will require senate confirmation.

“Today, I am honored to announce that I am nominating Air Force Lieutenant General Dan ‘Razin’ Caine to be the next Chairman of the Joint Chiefs of Staff,” Mr. Trump said in a message on Truth Social. “General Caine is an accomplished pilot, national security expert, successful entrepreneur, and a ‘warfighter’ with significant interagency and special operations experience.”

Secretary of Defense Pete Hegseth said in an announcement that he is also relieving Chief of Naval Operations Adm. Lisa Franchetti and Air Force Vice Chief of Staff Gen. James Slife of duty.

The decision to fire Brown, whom he nominated to serve as the Air Force chief of staff during his first administration, is the first in what could be a series of changes at the top of the Department of Defense.

“I have also directed Secretary Hegseth to solicit nominations for five additional high level positions, which will be announced soon,” he added.

Secretary of Defense Pete Hegseth said prior to his appointment to the position that he believed Brown should be fired over his support for the department’s diversity and inclusion efforts during the previous administration. Despite those comments, he gave Brown a nod of approval during his first day at the Pentagon last month.

“First of all, you’ve got to fire the chairman of the Joint Chiefs,” Hegseth said in an appearance on the “Shawn Ryan Show” in November.

After the president’s announcement on Friday, he said Brown “has served with distinction in a career spanning four decades of honorable service,” and added, “I have come to know him as a thoughtful adviser and salute him for his distinguished service to our country.”
