The Department of Commerce and the Treasury Department are two Poketops that pave the way toward the White House.
The White House Pokestop is now held by users Aizuh, Pokepam, Jheero08. Players can access the Gym outside the gate by the North Fountain. I asked a White House security officer whether he had any problems with Pokémon Go players trying to access the grounds but he wasn’t familiar with the game.
