Stephen Feinberg was confirmed by the Senate Friday to become deputy secretary of defense.

“His appointment is well-deserved, and he’s the right man for the job, the stakes couldn’t be higher. Let’s get to work,” Defense Secretary Pete Hegseth said, according to a DOD release.

Feinberg will largely run the Pentagon’s day-to-day operations and told lawmakers last month that his predecessors have not scrutinized the department’s activities closely enough.

“In my humble opinion, at times, some of the people in the operational execution jobs are not involved in detail,” Feinberg said during his confirmation hearing. “We’re going to set up a war room if I’m fortunate enough to be confirmed, and we’re going to go over every program, every cost, line by line, with an army of people until it’s done.”
