Defense Secretary Pete Hegseth has forced Colonel David Butler, a key communications chief for Army Secretary Dan Driscoll, into retirement, escalating a power struggle within the Pentagon. This action, stemming from ongoing tensions between top Trump administration officials, saw Hegseth instruct Driscoll to dismiss Butler during a meeting last week. Butler, who was nominated for promotion to brigadier general, had his advancement blocked by Hegseth for reasons yet to be clarified. Butler subsequently chose to retire to avoid further delaying his colleagues' promotions. This move occurs as Driscoll is engaged in crucial diplomatic talks regarding the Russia-Ukraine war, while Hegseth focuses on military restructuring and defense industry modernization. The article suggests Butler's prior role as spokesperson for General Mark A. Milley, a target of Trump and Hegseth, may have contributed to his dismissal.
