It depends. If the GOP Congress accepts Trump as a fellow Republican, they will do his bidding up to and including destroying the planet. After all, Congess is mostly political hacks, and everything is measured in terms of political consquences. If they don't accept him as a fellow R, they'll shut him down. But most GOP hacks get their marching orders from interests that collide with environmental protection, so I anticipate wholesale slaughter of natural resources at least through the mid-terms.
