By now you've heard there was a budget deal signed by the President. The deal re-opened the shuttered federal government, but only through March 23.
It also sets the overall amount of money the federal government has, but not individual agency allocations. As Politico noted, it sets the overall size of the pie, but did not establish the size of the slices that each agency gets.
Between now and March 23, Congress needs to fight about the appropriation that each agency will receive. That exercise needs to be completed by March 23. If they don't succeed by the deadline, the government will either again close its doors, or they will need to pass another continuing resolution.
