There is no place to leave your personal belongings in the
White House , I recommend leaving them at the Union Station left luggage facility while touring the White House, then you can pick them up afterwards. Not convenient, but better than leaving it on the ground. It's on first floor, near where the the commuter trains arrive. Best Lockers (202) 898-1592 Street Level - Gate A-Luggage storage.
Station address: 701 First St. NE, Washington, DC 20002
If you are driving is only about 12 minutes away. Driving directions from the White house to the station:
