Congress approved a stopgap spending bill on Wednesday to avoid a potential government shutdown.
The president is expected to sign the continuing resolution, which will fund the federal government through December 9. Without the continuing resolution, funding to keep the government operating would run out at midnight Friday.
October 1 is the start of the new federal fiscal year.
American Federation of Government Employees National President J. David Cox Sr. voiced frustration with legislative leaders and yet another close call on a government shutdown.
"Averting a government shutdown with only days to spare is no reason to celebrate. Congress has merely kicked the can down the road for another 10 weeks, when we will face yet another budget showdown," he said via statement. "Public servants and American families deserve better. This November, we need to elect lawmakers who will lead this country forward and remove the obstructionists who are standing in the way of progress."
The short-term spending bill includes $1.1 billion to prevent the spread of the Zika virus, $500 million in disaster aid for flood-ravaged Louisiana as well as one year of funding for the Department of Veterans Affairs. The measure does not provide immediate aid to address the lead water-poisoning crisis in Flint, Michigan. Lawmakers plan to provide funding to Flint through a different bill. Senate and House versions of the Flint aid legislation are expected to be combined when lawmakers return for the post-election lame-duck session.
