The growing push by some Democrats to reshape the Supreme Court reignited this week as the court heard oral arguments in the Mississippi 15-week abortion ban case that has the potential to limit abortion access across the U.S.

The court heard arguments in Dobbs v. Jackson Women’s Health Organization on Wednesday, and legal analysts have suggested the conservative majority will strike down decades of precedent following Roe v. Wade, the landmark ruling that limited government restrictions on abortion. If it does, it would open the door for state legislatures to pass laws banning abortions prior to fetal viability.

Former President Trump appointed three justices who were confirmed to the high court, shifting the makeup to six GOP-appointed justices and three Democrat-appointed justices. As a result, Democratic lawmakers have called to remove the Senate filibuster requiring 60 votes to pass legislation to add more seats to the court.

Republicans have characterized efforts to expand the Supreme Court as “court-packing” and a political power play by Democrats.
