WASHINGTON (AP) -- House Republicans have introduced legislation to immediately infuse $1 billion into federal disaster aid accounts as part of a stopgap funding bill that's required to keep the government running past the end of the budget year on Sept. 30.

Overall, the measure would provide $3.7 billion in disaster aid, with more money likely to flow in future legislation.

The House move sets up a battle with the Senate, where Democrats are muscling through a separate $7 billion disaster relief measure on a different track. That legislation matches the administration's recent aid request.

Republicans seem to have the procedural edge in the clash, but the continuing tensions over how to deal with disaster aid come as the government's main disaster relief fund is on track to run dry within two weeks.
