President Joe Biden will order a bipartisan commission to study, over 180 days, whether to expand the Supreme Court, fulfilling a campaign promise urged by some Democrats who have called for adding seats to the bench or instituting term limits for justices.

Biden faced increasing pressure from members of his party after then-President Donald Trump named three justices to the court, resulting in a bench with a conservative 6-3 balance. One of those seats was filled days before the 2020 presidential election, when Justice Amy Coney Barrett was confirmed to the seat of the late Justice Ruth Bader Ginsberg.
