President Biden’s $1.9 trillion Covid-19 relief bill, the American Rescue Plan Act, passed the Senate 50-49 on Saturday. Chuck Schumer and Mitch McConnell addressed the Senate before the vote, which followed a more than 25-hour marathon of amendment votes that was completed only after a lengthy interruption while Democrats settled an intra-party dispute over unemployment aid. The measure, the American Rescue Plan Act, now heads back to the House, with Democrats aiming to have it signed into law next week. Enactment would hand Biden his first legislative victory and set the stage for work this spring on a massive infrastructure and manufacturing recovery bill that he wants. But because of changes made in the Senate to satisfy moderate Democrats, it’s not clear if more negotiations with progressives might be necessary to win final passage in the House.
