Nope. It's what the DHS Appropriation language says. It is CBP funding that Congress authorized to be transferred to FEMA for actual execution. Has absolutely nothing to do with the FEMA disaster relief funds.
A form of this program has appropriated by Congress since 2019. Hmmm....
I'll try once more. At some point, just admit you're wrong and move on.
Here from the Congressional Research Service report.....
Authority, Funding, and Allowable Activities
The DHS Appropriations Act, 2024 (P.L. 118-47, Div. C, Title II) directed Customs and Border Protection
(CBP) to transfer $650 million of its FY2024 appropriation to FEMA for the SSP. The funding is
to support sheltering and related activities provided by non-Federal entities, in support of relieving
overcrowding in [CBP] short-term holding facilities.
