The federal government is operating on a Continuing Resolution (CR) that funds government operations only through next Friday, March 23. Unless something is passed before then the entire federal government, including Social Security, will shut down.
Congress is working on an omnibus funding bill to fund all of the federal government through the rest of the fiscal year. In more normal times, this is done with a series of bills covering different parts of the federal government.
There are still disagreements over the omnibus and some predictions that another short CR will be needed.
The current draft or drafts of this bill have not been released to the public. There's no definite sign that Social Security's appropriation is in dispute but we can't be sure.
