A former top Pentagon spokesperson has slammed Pete Hegseth's leadership of the department of defense, as pressure mounts on the US's top military official following reports of a second Signal chatroom used to discuss sensitive military operations. John Ullyot, who resigned last week after initially serving as Pentagon spokesperson, said in a opinion essay published by Politico on Sunday that the Pentagon has been overwhelmed by staff drama and turnover in the initial months of the second Trump administration. Ullyot called the situation a "full-blown meltdown" that could cost Hegseth, a 44-year-old former Fox News host and national guard officer, his job as defense secretary.
