The resignation of Army Secretary Driscoll was not a surprise, though it brought renewed questions on the leadership of War Secretary Hegseth.

Dan Driscoll had been rumored to step down at some point between now and the end of the year but the White House announced his departure Monday.

Dan Driscoll, a former soldier who came into the roll from the finance world, reportedly had a strained relationship with Defense Secretary Pete Hegseth.

The development follows Driscoll publicly breaking with Hegseth's move to force Gen. Randy George, the ousted Army chief of staff, to retire.
