President Joe Biden says he plans to nominate Russell Rumbaugh as the Navy department’s top financial management official. Rumbaugh currently works as a systems director at the Aerospace Corporation’s Center for Space Policy. Before that, he served as a budget expert for multiple D.C. think tanks and for DoD’s office of Cost Assessment and Program Evaluation. The Navy comptroller’s position is one of many top civilian leadership jobs that have been vacant since the start of the Biden administration.
