I don't know if you actually GET in the white house, but the objective is to get to the west wing... and the white house is the only building with power, making it where you're heading... it's just a pain in the ass, because you have to sprint from tree to tree to foxhole meanwhile shooting bitches on the balcony and roof... there's a mounted gun back by where you start to come up on the white house lawn, but it seems like even if you manage to somehow use it to clear some out, that by the time you start moving, they've all respawned. Unfortunately, I only have the standard M4A1 ironsight grenade launcher and some sort of LMG (maybe?) with an ACOG. Neither good for long range pot shots.
