WASHINGTON — Congress is quickening its pace toward adjourning this week, marching toward a final vote on legislation boosting medical research and speeding drug approvals and readying a stopgap spending bill to prevent the government from shutting down this weekend.

The temporary budget bill to be unveiled today would keep federal agencies functioning into next spring, giving the new Congress and the incoming Trump administration time to approve more than $1 trillion to fund federal agencies through the Sept. 30 end of the current government budget year.

Current spending expires at midnight Friday. Since the measure is the only absolute must-do bill before Congress adjourns, it’s likely to carry several add-ons, including flood relief, money for overseas military operations, and help for Flint, Mich., to fix its lead-tainted water system. Other possibilities include language to help speed a congressional waiver required next year to confirm retired Gen. James Mattis as secretary of defense and help to maintain health benefits for retired members of the United Mine Workers. Lawmakers will deny themselves a cost-of-living pay hike.

The overall measure would keep the government running through April 28.

The Senate, meanwhile, appears on track today to pass the $6.3 billion biomedical bill, which includes a $1.8 billion cancer research “moonshot” strongly supported by Vice President Joe Biden, whose son Beau died of the disease, as well as $1 billion over two years to prevent and treat abuse of opioids and other addictive drugs like heroin. The nearly 1,000-page package cleared the House last week, with backing from President Barack Obama.
