Not all laws!
Congress can override a presidential veto and thus pass a law the President did not sign
This “commission, etc.” is just fodder for the Rat “crazies”, keeps them energized. Nothing will pass that will have any real force of law. It gives Rat Congresscritters something to point to so they can say, “See I tried to stop Trump!”.
Well, you are correct, but if there are 290 votes in the House to establlish such a commission, and 67 votes in the Senate, then impeachment is a snap, and would be much less controversial.
