Former chief Pentagon spokesman John Ullyot, who was once a strong backer of Defense Secretary Pete Hegseth, is now warning that the “total chaos” of the last month at the Defense Department, including Signalgate and the recent firings over supposed leaks, could lead to Hegseth’s ouster.

In an op-ed in Politico, Ullyot detailed his shift from once arguing that Hegseth was the “best man to shake things up” at the DOD to now observing that the Pentagon is in “disarray” under his leadership and that he may not have much time left as defense secretary.
