The compromise, announced by the West Virginia lawmaker and a Democratic aide late Friday, seemed to clear the way for the Senate to begin a climactic, marathon series of votes and, eventually, approval of the sweeping legislation.
The overall bill, President Joe Biden's foremost legislative priority, is aimed at battling the killer pandemic and nursing the staggered economy back to health. It would provide direct payments of up to $1,400 to most Americans and money for COVID-19 vaccines and testing, aid to state and local governments, help for schools and the airline industry and subsidies for health insurance.
The Senate next faced votes on a pile of amendments that were likely to last overnight, mostly on Republican proposals virtually certain to fail but designed to force Democrats to cast politically awkward votes.
More significantly, the jobless benefits agreement suggested it was just a matter of time until the Senate passes the bill. That would ship it back to the House, which was expected to give it final congressional approval and whisk it to Biden for his signature.
White House press secretary Jen Psaki said Biden supports the compromise on jobless payments.
The day's lengthy standoff underscored the headaches confronting party leaders over the next two years — and the tensions between progressives and centrists — as they try moving their agenda through the Congress with their slender majorities.
