See, Trump can't piss off the Senate TOO bad, or they'll roll over to the Dems on judges.
My best idea would be to abolish DHS (I think it was created by Executive Order), and just have the military staff the border.
Or better yet, the FBI (it'll keep them out of D.C.)
It was not created by Exec Order. It was passed by Congress. A president can’t magically create/abolish cabinet level departments.
