The president did not approve their “law” therefore it is not a law and is meaningless. There are three co-equal branches of government and the senate is only half of one branch.
Trump could tell the senate that they can’t take a crap for a year. That does not make it a law and the senate could still crap when nature stirs them, although I would agree that those losers should have giant anus screws with locks to prevent cheating.
I agree Trump shoe form a search party right now. That would make them think.
Trump can also call Congress back into session and he should because it is a national emergency.
