President Trump intends to nominate the Pentagon's acting Chief Management Officer Lisa Hershman to serve in the post as a Senate-confirmed official.
Hershman has been in the acting role since Dec. 1, 2018, after former CMO Jay Gibson resigned.
Government officials say Gibson was forced out by then-Defense Secretary Jim Mattis, who was underwhelmed by the office's effort to shave excess spending.
Pentagon officials say they expect Hershman's nomination to be addressed after those of Mark Esper, Trump's pick to be defense secretary, and David Norquist, the president's pick for deputy defense secretary.
Esper's confirmation hearing is scheduled for Tuesday morning.
