The funding for DHS, FEMA, and their various programs is multi-layered through multiple channels; FEMA is kind of in control of the Disaster Relief Fund (DRF), which is intended ONLY as a frontline defense for emergencies, while Congress decides on allocating additional funds for each major emergency. And these latter funds remain locked for use only for the given emergency for years. However, please note that almost every fund is marked as "discretionary" in their budget documents. FEMA supposedly can't divert funds from DRF. But all the funds go into one slush fund that can have funds "borrowed" for one cause or another - to be returned at some latter date. Ask the federal accountants and treasurers about the mechanics of doing that. But yes, they most likely CAN obtain funds from the DRF through bookkeeping machinations. Especially, when some of these funds have been sitting idle for more than a decade (e.g. where does the interest on these funds go?).
DHS budget is split into different programs, via itself, FEMA and the CBP (US Customs and Border Protection), and Emergency Food and Shelter Program - and they do this through a number of grants. It appears the grants for 2022-2024 amount to about $2B. Now, one could say it is really the DHS who is divying up its budgeted funds to different departments rather than FEMA.
FEMA takes the view, that once Congress allocates funds to the DRF, they remain with the DRF. But is that just an accounting ploy? So, yes, you can say a fund exists for the DRF of so many billions of dollars - on the books. But in reality, in the chart of accounts, cash assets can be replaced by debts (or notes) receivable, and when some auditor looks at these books, all the accounts still in balance, - and of course, they report precisely what they see in some report that goes to Congress oversight, who sees the Account Receivables booking and probably considers it just as normal as for any business, as long as the ratios are acceptable.
Now, Trump understands all of this gimmickry - but not the public. So what does Trump do? He simplifies things and leaves the details till later, which will never come, because the Democrat leadership is certainly intelligent enough to know how this works.
Then we have the Dodos on this forum, who think they understand what they are discussing, -- but should know better.
The Department of Homeland Security (DHS), through the Federal Emergency Management Agency (FEMA) and U.S. Customs and Border Protection (CBP), announced more than $77 million in grants to support border and interior communities receiving migrants through the Shelter and Services Program (SSP).
