Trump has never abandoned the work of tax reform nor dismantling the bureaucracy. He should definitely not drop this thing as it goes to the heart of "draining the swamp". When you have beaten your enemy down, you don't let them back up. You continually stomp their heads until their eyes bulge out. (or until they are dead, which ever comes first)
Love your attitude, and, no, Trump never stopped. He puts cheese in the maze to distract every couple of days
