A single person shut down the entire U.S. government for the first time in 17 years.
Not a congressman, but an unelected woman named Sylvia Burwell who, as the relatively new director of the Office of Management and Budget, sent the email that initiated the process that has closed national parks, visitors centers and even the panda-cam at the National Zoo.
....the same woman who ordered the shutdown of the war memorials during the so-called government shutdown last year.
