WASHINGTON — Republicans controlling Congress Tuesday unveiled $10 billion in supplemental war funding and $4 billion more for disaster relief for Louisiana and other states as key additions to must-pass legislation to keep the government running into next spring.

The bill would also deliver $170 million in long-delayed help for Flint, Michigan, to fix its lead-tainted water system.

The legislation would prevent the government from shutting down this weekend and buy several months for the new Congress and incoming Trump administration to wrap up more than $1 trillion worth of unfinished agency budget bills.

Democrats complained the GOP measure shortchanged New York City by giving it just $7 million, rather than the $35 million requested, to cover police overtime and other security costs for President-elect Donald Trump, who lives in midtown Manhattan. And they complained that a provision to help retired Appalachian coal miners keep their health benefits for a few months was woefully inadequate.

The bill attracted attention as the final legislative locomotive to leave the station before Congress closes shop this year. Nothing else on Capitol Hill’s agenda had the power to tow other unfinished legislation into law.

The White House and mainstream Republicans were denied in a bid to revive the Export-Import Bank’s ability to approve export financing deals exceeding $10 million. But the trucking lobby appeared poised to win permanent relief from recent Transportation Department rules mandating longer rest breaks for long-haul carriers.

Democrats complained about a proposal to help speed a congressional waiver required next year to confirm retired Gen. James Mattis as secretary of defense. Mattis would otherwise be ineligible to serve because of a law that requires a seven-year wait for former members of the military to serve in the post. A late change aimed at mollifying Democrats would maintain the 60-vote filibuster threshold to deliver the waiver.

One major dispute centered on protecting health care benefits for about 16,000 retired coal miners facing the loss of coverage on Dec. 31.

The measure had divided coal-state Republicans. Several supported longer-term legislation tackling the loss of health care, but GOP leaders – including Senate Majority Leader Mitch McConnell of Kentucky – were wary of bailing out unionized workers.

McConnell said Tuesday that the temporary health care help for miners would be part of the spending bill. Sen. Joe Manchin, D-W.Va., protested that the fix would last just a few months and vowed to push for a permanent solution.
