congress is not a superior branch to the executive
they have no power to limit how and when a president appoints to the surpreme court
this clearly demonstrates they care nothing for the law and only want things in place to make things better for THEM and their plans
they care nothing if it makes government worse or cripples a particular branch of government if it works in their favor
"The Congress, whenever two thirds of both Houses shall deem it necessary, shall propose Amendments to this Constitution, or, on the Application of the Legislatures of two thirds of the several States, shall call a Convention for proposing Amendments, which, in either Case, shall be valid to all Intents and Purposes, as Part of this Constitution, when ratified by the Legislatures of three fourths of the several States, or by Conventions in three fourths thereof, as the one or the other Mode of Ratification may be proposed by the Congress; Provided that no Amendment which may be made prior to the Year One thousand eight hundred and eight shall in any Manner affect the first and fourth Clauses in the Ninth Section of the first Article; and that no State, without its Consent, shall be deprived of its equal Suffrage in the Senate."
Terms of appointment for Federal Judges is fixed by law, and could theoretically be changed. Of course the President’s signature is required on any bill unless there is a 2/3 supermajority in both houses of Congress that will vote to override a veto. This is a political stunt intended for the leftwing base. I’m not losing sleep.
