Health Care Trust Fund; reestablish and transfer $1 billion into.

HB 663 reestablishes Mississippi's Health Care Trust Fund, directing the transfer of $1 billion from the Capital Expense Fund to create a new principal balance. The bill requires the fund's principal to remain untouched ("inviolable") and mandates that only investment earnings (not the principal) be used for healthcare purposes. It aims to restore the original 1999 vision of a growing, perpetual healthcare funding source from tobacco settlement payments. The fund would be managed separately, with earnings exclusively allocated for healthcare programs under legislative appropriation.
