President Trump passed the two-year mark in his administration with a Cabinet filled with “acting” secretaries, raising concerns about the ability of agencies to implement policies effectively.

Acting secretaries currently helm three federal agencies: the Department of Defense, the Department of the Interior, and the Environmental Protection Agency. The U.S. ambassador to the United Nations is also a temporary stand-in, as is the director of the Office of Management and Budget. An acting attorney general ran the Justice Department until Thursday, when the Senate confirmed William Barr to head the agency on a permanent basis.
