There is a consent decree the Republicans signed preventing them from doing that.

Well, I am an American, not a Republican or Democrat, and it is long past time we flushed Congress and brought the Government back under the limitations of the Constitution. Our law structure is so in opposition to the Constitution, its foundation, that very little fits inside those limitations these days. Law precedent should not override plain text, and tends to be circular logic. With circular logic as a guide, you can make statements that are clearly false such as you cannot stop corrupt voting, or illegals are entitled to social security funds.
All of that is crap, and a fifth grader knows it. Too bad our Judges are too corrupt to be smarter than a fifth grader.
