The Senate — following a grueling vote-a-rama on Friday and Saturday — has finally approved a $1.9 trillion Covid-19 relief bill, bringing it one step closer to becoming law.

The legislation, which passed 50-49 on a purely party-line vote, with Sen. Dan Sullivan (R-AK) not voting due to a family funeral, now heads back to the House, where a vote is expected as early as Tuesday. This step is significant and follows intense back-and-forth in the upper chamber over multiple provisions, including some — like the $15 minimum wage — that were stripped out for procedural reasons, and others, like unemployment insurance, that have been changed in response to pressure from moderate Democrats.
