Wormuth to step down

Under Secretary of Defense for Policy Christine Wormuth will step down in June, according to a statement issued today by Defense Secretary Ash Carter.

Wormuth will leave "to spend more time with her family," Carter said in the statement.

He said Brian McKeon, Wormuth's principal deputy, will serve as acting under secretary of defense for policy, and David Shear, assistant secretary of defense for Asian and Pacific security affairs, will assume McKeon's responsibilities.
