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.
