Senate Democrats struck a deal Friday evening on extending unemployment insurance in the President Biden's $1.9 trillion COVID-19 relief package after deliberating for most of the day, per a Senate aide.

Why it matters: The deal allows Congress to move forward with voting on amendments to the bill, though it caused a massive delay in the 20-hour debate over the legislation.

• Sen. Joe Manchin (D-W.V.) backed his party’s proposal, after reluctance to support an earlier version.

The big picture: Democrats will now offer an amendment extending the enhanced unemployment insurance of $300 per week through Sept. 6. The bill passed by the House pushed the program through Aug. 29.
