President Donald TrumpÂ has announced that Deputy Defense Secretary Patrick Shanahan will serve as secretary of the Department of Defense on an interim basis starting Jan. 1, Military Times reported Sunday.
Mattisâ decision to leave the Pentagon reportedly stemmed from the presidentâs policies on national security such as his decision to pull out U.S. troops from Syria and previous views on foreign allies, according to the report.
Shanahan was confirmed by the Senate for the deputy defense secretary role in July 2017. Prior to DoD, he served as senior vice president of supply chain and operations at BoeingÂ (NYSE: BA).
He has pushed for changes to the Pentagonâs acquisition system and led efforts to eliminate duplicative programs, the report added.
