Shut it, Chuckie:
One of the most wearisome aspects of politics is the party that doesn't have the White House at the time complaining about presidential overreach as if it weren't happening all the time, especially in the last decade or so. Schumer didn't think the Constitution was being trampled upon when The Lightbringer was doling out executive orders like they were candy on Halloween. Trump is actually a little light on national emergencies compared to his predecessors too.
A lot of the Executive branch hyperactivity is Congress's fault anyway. Both chambers have devolved into media grandstanding and kicking the can down the road for future legislators. On many important issues (illegal immigration, for example) they have all but abdicated their legislative responsibilities. Into that void steps whichever president happens to be in office.
Do your damn job, Chuck.
