Appropriation

A law passed by Congress that authorizes federal agencies to spend a specific amount of money for a specific purpose during a defined period.

How It Works

Appropriations are how Congress controls the federal purse. The annual appropriations process begins with the President's budget request, followed by Congressional hearings, committee markups, and floor votes. There are 12 annual appropriation bills covering different parts of the government. When Congress can't pass all 12 bills on time (which is most years), it passes a Continuing Resolution (CR) to fund the government at prior-year levels temporarily. If neither appropriations nor a CR is enacted, the government shuts down.
