Congressional Appropriations in AP US Government
Congressional appropriations are laws passed by Congress that provide federal money for specific agencies and programs, usually for one fiscal year. The Constitution says no money can leave the Treasury except through appropriations made by law, so this is Congress's power of the purse. When Congress can't agree on these bills, the result can be a stopgap continuing resolution or a government shutdown.
This definition is part of Fiveable's AP US Government review, which also has guided practice questions.
Authorizing a program vs. appropriating money for it
The mix-up that costs points is treating authorization and appropriation as the same thing. An authorization creates or continues a program or agency and sets the rules for it, sometimes with a ceiling on spending. An appropriation provides the legal authority to actually spend money.
These two kinds of authority are often enacted in separate bills, but both can appear in the same law. What matters is the difference in what each one does.
A program can be fully authorized and still sit unfunded if Congress never appropriates money for it. A quick way to hold the difference: authorization gives permission to exist, and appropriation writes the check.
The constitutional anchor is Article I, Section 9, which says money can only be drawn from the Treasury "in Consequence of Appropriations made by Law." That clause is why the House and Senate Appropriations Committees matter so much inside the committee system. They write annual spending bills that fund many federal agencies and programs.
Why yearly spending bills stall under polarization
Appropriations come with a hard deadline, which makes them a clean example for Topic 2.3: Congressional Behavior in Unit 2: Interactions Among Branches of Government. That topic asks how partisanship, polarization, divided government, and elections shape what Congress actually gets done.
The fiscal year starts October 1. To keep funding going that expires then, Congress has to pass new appropriations or a continuing resolution through both chambers and get the president's signature, unless it overrides a veto.
When parties are polarized and members vote along party lines, reaching consensus on spending gets harder. That can produce gridlock, the course's term for Congress being unable to act. Divided government raises the stakes, since one party in the White House and the other controlling at least one chamber means either side can block a spending bill.
When deadlines slip, there are two common outcomes. Congress can pass a continuing resolution, which temporarily keeps funding at roughly current levels, or it can miss the deadline and trigger a shutdown of agencies that lack funding. The shutdown that began in December 2018 lasted 35 days, making it the longest at the time, and centered on a dispute over funding for a border wall.
The president's budget is a request; the appropriation is the law
A second confusion is giving the president the spending power. The president sends Congress a budget proposal each year, but that document has no legal force on its own. Congress can rewrite it, ignore parts of it, or fund things the president didn't ask for. The president's leverage comes later, through the veto and through negotiation.
That's why appropriations count as a check in the Unit 2 story of branches limiting each other. Congress can shrink an agency's funding, attach conditions to how money is spent, or refuse to fund a president's priority, all without passing a new policy law. Funding decisions often follow congressional oversight hearings, where committees question agency officials about how earlier money was used.
Earmarks connect here too. They're provisions in spending bills that direct money to specific projects, often in a member's home district. They show the delegate side of representation, a member using the budget process to deliver for constituents.
Writing a stalled spending bill into a Concept Application answer
The concept fits several exam tasks. In multiple choice, a question might ask which branch controls federal spending, or what happens when Congress misses a funding deadline. A stimulus might be a news excerpt about a shutdown or a chart of continuing resolutions across years, and you'd connect it to polarization or divided government.
For Question 1 (Concept Application), a scenario about a budget standoff between a president and an opposing-party House is a natural fit. A strong answer names the behavior (partisan voting, divided government), explains the mechanism (appropriations require majority support in both chambers before money can be spent), and states the effect (gridlock, a continuing resolution, or a shutdown). For Question 2 (Quantitative Analysis), the same chain helps you link a pattern in data on shutdowns or late budgets back to party conflict.
The wrong answers to avoid: writing that "the president sets the budget," or that authorizing a program automatically funds it. Say that Congress must pass an appropriation before an agency can spend, then explain what partisanship does to that process.
