This supreme court has been stomping the other branches of government.
Congress created the EPA. If they don't like what they created, it's on them to fix it.
Congress delegating it’s power is suspect at best, and likely unconstitutional entirely (something something, War Powers Act).

Making law is Congress’ job.
