WASHINGTON �� President Donald Trump said Sunday that he would replace outgoing Defense Secretary James Mattis with his top deputy, Patrick Shanahan, as of Jan. 1, ending the former general's tenure two months before he had planned to leave the Pentagon.
Mattis announced his resignation last week in a letter emphasizing his policy differences with the president, but he said he would stay on the job until Feb. 28. The retired Marine Corps general quit after Trump announced his plans to withdraw U.S. troops from Syria and Afghanistan.
Shanahan is a former Boeing Co. executive who joined the administration in 2017.
