I googleg my own question and I got this reply :
A budget rescission is the cancellation of previously approved government funding. It’s a process where the President can propose to Congress to eliminate previously allocated funds for specific programs before they are spent. Congress then has to approve the rescission for it to take effect.
Here’s a more detailed explanation:
Previously Appropriated Funds:
Rescissions involve money that has already been approved by Congress through the appropriations process, but has not yet been spent by the government.
Presidential Proposal:
The President can propose rescissions to Congress, essentially asking them to cancel the spending of those funds.
Congressional Action:
Congress must then act on the President’s proposal. They can either approve the rescission, effectively canceling the funding, or they can reject it, meaning the money will remain available for spending as originally intended.
Impoundment Control Act:
The Impoundment Control Act of 1974 provides the legal framework for the President’s rescission authority.
Purpose:
Rescissions can be used to reduce the overall budget deficit, redirect spending to other priorities, or signal a change in policy direction.
Good. They can pass with a simple majority. Expect a ton of them.
Don't you feel better now?
