@Kozmo except, that sort of thing violates the notion that we have an independent judiciary.
You can't both have an independent court and a Congress with such power over it. The two are contradictory.
We already have a solution here: impeachment. It is the one and only way to address such a situation, should it be warranted.
Of course, in this case Jeffries just comes across sounding like a partisan, an extremist stirring the pot for political points.
