Leading Republican Sens. Marsha Blackburn (R-Tenn.), Ted Cruz (R-Texas), and Lindsey Graham (R-S.C.) on Thursday held a press conference expressing their opposition to the Democrat proposal to expand the Supreme Court from 9 to 13 seats.

The three senators compared the Democrat-led effort as a push to “rig” the Supreme Court that would ultimately “destroy judicial independence.”

“Packing the court and tearing down the institutions that protect our rights is fundamentally wrong,” said Cruz at a press conference in front of the Supreme Court. “They’re [Democrats] trying to rig the game … fix the system.”

The Judiciary Act of 2021, which was put forward last week, would add four seats to the nation’s top court, effectively flipping the balance from six to three in favor of conservative-appointed justices, to seven to six in the opposite direction.

Lobbying efforts by liberal activists to “pack the court” have ramped up in recent months following their unsuccessful attempt last year to stop then-Judge Amy Coney Barrett’s nomination.

Sen. Ed Markey (D-Mass.) introduced the bill with Reps. Jerrold Nadler (D-N.Y.), Hank Johnson (D-Ga.), and Mondaire Jones (D-N.Y.).
