The stopgap measure would keep the government running through Sunday while congressional leaders try to finalize a full-year funding and coronavirus relief package.The Senate will have mere hours to approve the bill before government funding expires. Any one senator can block swift passage of legislation in the chamber.Senators including independent Bernie Sanders of Vermont and Republican Josh Hawley of Missouri suggested they could delay approval of a spending bill as they lobby for leadership to include a $1,200 direct payment in a pandemic aid package. Hawley, for his part, tweeted that he would not block the legislation after top Republicans assured him a final relief deal would include “direct assistance to working people.” Lawmakers are expect to include $600 payments, down from the $1,200 checks approved as part of the CARES Act in March.The House initially tried to pass the funding bill unanimously on Friday. However, Rep. Chip Roy, R-Texas, objected and forced a full recorded vote.The move delayed the bill’s passage by more than an hour as Congress worked on a tight schedule to beat the shutdown deadline. The House approved it in a 320-60 vote.Lawmakers, for the second time this month, aim to give themselves more time to package a full-year spending bill and money to lift a health-care system and economy buckling under a relentless coronavirus outbreak. They already approved a one-week extension that kept the lights on through Friday.Congressional leaders have said for days that they are close to a desperately needed pandemic aid agreement.

Democrats say the measure would hamstring President-elect Joe Biden’s ability to respond to the ongoing economic crisis after he takes office on Jan. 20.Along with direct payments, the developing plan would include a $300 per week federal unemployment supplement. It would extend a pandemic-era expansion of jobless benefits, which 12 million people would lose the day after Christmas.It is unclear now how the proposal would handle a federal eviction moratorium. The provision lapses at the end of the year, potentially leaving millions vulnerable to eviction.The package would put at least $300 billion into small business aid. It would include money for Covid-19 vaccine distribution and testing, along with relief for hospitals.It would also direct funding to schools, which have had to adapt to stay open or go virtual during the pandemic.The bill will not address state and local government support or liability protections for businesses. Those issues divided Democratic and Republican leaders.Democrats and many rank-and-file GOP lawmakers, along with bipartisan governors, supported state and local aid as necessary to preserve first-responder jobs and allow officials to contain the pandemic.
