On Jan.20, what former White House usher Gary Walters once called a “very well-organized ballet choreography,” took place in just five short hours within 132 rooms of the White House as the Obama family departed and the Trumps made 1600 Pennsylvania Ave. their new “home on loan.” The famous Washington, D.C. address, the national landmark where American presidents live and work, belongs to all American citizens.
