From the text of the bill referred in the previous post:
"SEC. 4501. (a) IN GENERAL.—Notwithstanding any other provision
of law, including any agreement, the Federal share of assistance,
including direct Federal assistance, provided for the States
of Louisiana, Mississippi, Florida, Alabama, and Texas in connection
with Hurricanes Katrina, Wilma, Dennis, and Rita under sections
403, 406, 407, and 408 of the Robert T. Stafford Disaster Relief
and Emergency Assistance Act (42 U.S.C. 5170b, 5172, 5173, and
5174) shall be 100 percent of the eligible costs under such sections."
Seems pretty clear cut. Obama lied.
