WhiteHouse.gov is saying that DJT signed the bill.
He is asking for rescissions using the Impoundment Control Act of 1974, but I don’t know how effective that is or if Congress can just ignore it.

Recission
"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."
Deferrals
"The ICA defines a “deferral” as withholding, delaying, or – through other Executive action or inaction – effectively precluding funding from being obligated or spent. The ICA prescribes three narrow circumstances in which the President may propose to defer funding for a program: (1) providing for contingencies; (2) achieving budgetary savings made possible through improved operational efficiency; and (3) as specifically provided by law. The ICA requires that the President send a special message to Congress identifying the amount of the proposed deferral; the reasons for it; and the period of the proposed deferral. Upon transmission of such special message, the funds may be deferred without further action by Congress;"
