The Democratic bill is led by Sen. Ed Markey of Massachusetts and Rep. Jerry Nadler of New York, the chair of the House Judiciary Committee. It is co-sponsored by Reps. Hank Johnson of Georgia and Mondaire Jones of New York... The lawmakers, who intend to announce the introduction of the bill outside the Supreme Court building, will be joined by progressive activists Aaron Belkin, who leads Take Back the Court; Chris Kang, a co-founder and chief counsel of Demand Justice; and Meagan Hatcher-Mays of Indivisible, according to an advisory notice. All three groups advocate adding justices. "This bill marks a new era where Democrats finally stop conceding the Supreme Court to Republicans," said Brian Fallon, a former Senate Democratic leadership aide and a co-founder of Demand Justice, who described the court as "broken and in need of reform."
