WASHINGTON — In the spring, Defense Secretary Pete Hegseth decided not to promote a senior Army officer who had led troops over five tours in Afghanistan and Iraq because Hegseth suspected, without evidence, that the officer had leaked sensitive information to the news media, according to three people with knowledge of the matter.
When Lt. Gen. Douglas A. Sims II was cleared of the allegations, Hegseth briefly agreed to promote him, only to change course again early this month, the officials said. This time, Hegseth maintained that the senior officer was too close to Gen. Mark Milley, a former chair of the Joint Chiefs of Staff whom President Donald Trump has accused of disloyalty.
Hegseth’s sudden reversal prompted a rare intervention from Gen. Dan Caine, the current chair of the Joint Chiefs. He urged Hegseth to reconsider, said the officials, who spoke on the condition of anonymity to discuss internal deliberations.
Hegseth met with Sims one final time but refused to budge. Sims is expected to retire in the coming months after 34 years in the military, officials said. Through a spokesperson, Sims and Caine declined to comment. A Pentagon spokesperson declined to comment on Hegseth’s role.
The standoff over his promotion reflects an ongoing clash between Hegseth’s highly partisan worldview, in which he has written that the Democratic Party “really does hate America,” and the long-standing tradition of an apolitical military that pledges an oath to the Constitution.
Hegseth’s actions could shape the military’s top ranks for years to come. His insistence on absolute loyalty, backed with repeated threats of polygraphs, also creates uncertainty and mistrust that threaten to undermine the readiness and effectiveness of the force, officials said.
The tension between top military officers and their civilian leaders has been persistent since the earliest days of Trump’s second term, when senior administration officials ordered the removal of Milley’s portrait from a Pentagon hallway.
Caine, who pressed Hegseth on Sims’ behalf, got the job of Joint Chiefs chair after Hegseth and Trump fired Gen. Charles Q. Brown Jr., his predecessor. Hegseth accused Brown, who is Black, of prioritizing diversity over the combat effectiveness of the force.
