Shanahan’s confirmation for the Defense Department‘s no. 2 civilian post comes as the Trump administration’s 40 nominees for federal government roles face Senate vote delay.
The Senate Armed Services Committee approved his nomination on June 28.
He will succeed Robert Work, who is set to hand over a dozen reviews to Shanahan.
Shanahan is a three-decade Boeing veteran who previously served as VP and general manager of the aerospace and defense company’s missile defense systems and rotorcraft systems segments.
