In the United States, President Donald Trump's choice, Philip Bilden, has withdrawn his nomination as Secretary of the US Navy. Defense Secretary Jim Mattis said in a statement that the withdrawal was a personal decision driven by privacy concerns and significant challenges he faced in separating himself from his business interests. He said President would soon suggest a new nominee.<br/><br/>The secretary of the Navy serves as the chief executive officer for both the Navy and the Marine Corps. Bilden's move came on the heels of similar decisions by US Army secretary nominee Vincent Viola, and Labor Secretary nominee Andrew Puzder.
