@dickflatteningenthusiast as i have just learned, the president does not need any permission from congress to do this. he can just do it. the only reason why he'd need that is if it were publicly funded. since it is privately funded, it's fair game.
also, it's fucking hilarious to complain about it being privately funded, especially if they don't want it there in the first place. "how dare they put something i don't want in the white house without using my money to do it!"
