President Biden and his party searched for a way forward on their ambitious agenda after one of their own, Joe Manchin III, closed the door on ending the filibuster.

Mr. Schumer said on Monday that he had no intention of shelving the voting rights bill, which would nullify laws passed by 14 Republican-controlled state legislatures to curtail early and mail-in voting, empower partisan poll watching and give elected legislatures more power over election outcomes. Senate Democrats were to meet on Tuesday to discuss the path forward, the same day Mr. Manchin was set to meet with Derrick Johnson, the president of the N.A.A.C.P., and Marc Morial, the president of the National Urban League, to hear their pleas for his support.
Regardless of Mr. Manchins position, Mr. Schumer said a vote would be called the week of June 24, as planned, to protect voting rights and American democracy.
My colleagues need to be put on the record and held accountable, Senator Richard Blumenthal, Democrat of Connecticut, said on Monday.
At the same time, Mr. Biden and Senate Democratic leaders were working to keep Mr. Manchin on board with a push for a major infrastructure package. Mr. Biden was scheduled to speak again on Tuesday with Senator Shelley Moore Capito of West Virginia, the lead Republican negotiator, to discuss the scope of an infrastructure bill and how to pay for it. And senators were engaging Mr. Manchin on potential enticements for his vote, such as a long-sought clean manufacturing initiative that has already been incorporated in the Finance Committees provisions to pay for spending on roads, bridges, tunnels and transit.
Still, Democrats had to concede that their initial efforts to sway Mr. Manchin on perhaps their highest priority the voting rights measure had fallen flat after a weekslong effort. Democrats had been pursuing an inside-outside approach, deploying liberal organizations and civil rights activists to pressure Mr. Manchin politically, while small groups of senators reached out to him privately to identify his substantive concerns with the voting rights bill and what could be tweaked or jettisoned to win him over.
But Mr. Manchin did not lodge any specific policy objections that could be resolved. He simply wanted at least one Republican to support the bill effectively handing a veto to the minority party.
