Biggs proposes constitutional amendment establishing that Supreme Court should have nine justices

House Freedom Caucus Chair Rep. Andy Biggs is proposing a constitutional amendment to fix the number of Supreme Court justices at the current level of nine.

"The Supreme Court of the United States shall be composed of nine justices consisting of one chief justice and eight associate justices," the amendment would say, according to The Hill which reported that it had acquired a copy.

Several congressional Democrats on Thursday unveiled legislation which would boost the number of Supreme Court seats to 13.

"The Supreme Court must faithfully interpret the Constitution. We cannot allow it to fall victim to partisan attempts to pack it with far-left radicals," Biggs, an Arizona Republican, said in a statement, according to The Hill. "This desperate power-grab by Democrats will only further divide our Nation. I will not stand for a 'Supreme Coup' of our highest court."
