WASHINGTON—Senate Democrats passed President Biden’s $1.9 trillion coronavirus relief package Saturday by the slimmest of margins, following an intraparty standoff over unemployment benefits.
The Senate approved the package along party lines, 50-49, after deliberating all of Friday and into Saturday morning. The package now heads back to the House, which must approve the Senate-revised legislation before sending it to the White House for Mr. Biden’s signature. The House is expected to take up the measure next week.
The legislation would provide $300 in weekly unemployment benefits through Sept. 6, send $1,400 direct payments to many Americans, direct $350 billion to state and local governments, fund vaccine distribution and expand the child tax credit, among other aid.
