House Republicans are hoping to vote Tuesday on a stopgap bill aimed at funding the federal government through September 30 and preventing a shutdown after Friday.

U.S. Senate Democrats were wrestling on Wednesday with how to respond to a stopgap funding bill passed by the Republican-controlled House of Representatives, choosing between voting for a bill many of them oppose or allowing a government shutdown.

House Republicans passed a critical test of their unity on legislation to avoid a partial government shutdown, teeing up a final vote for a measure that keeps federal agencies funded through September.
