WASHINGTON—President Donald Trump nominated Mark Esper on Monday afternoon to succeed Gen. Jim Mattis as secretary of defense. The Department of Defense has not had a confirmed head since Mattis’ resignation in December. Following the nomination, Esper had to step down from his position as acting defense secretary while he goes through the Senate confirmation process, which could conclude as early as Thursday after a hearing on Tuesday.
