So?
The law has passed. It is the law.

Rescissions
Put simply, if the President wants to spend less money than Congress provided for a particular purpose, he or she must first secure a law providing Congressional approval to rescind the funding in question. The ICA requires that the President send a special message to Congress identifying the amount of the proposed rescission; the reasons for it; and the budgetary, economic, and programmatic effects of the rescission. Upon transmission of such special message, the President may withhold certain funding in the affected accounts for up to 45 legislative session days. If a law approving the rescission is not enacted within the 45 days, any withheld funds must be made available for obligation.
