I believe the total authorized by Congress for Katrina and Rita assistance is somewhere around 110 billion dollars to be spread among all the states involved, Florida, Alabama, Mississippi, Louisiana and Texas. Louisiana will get the most because they suffered the most damage.
It should be noted though that nowhere near that amount of money has actually been distributed yet. In the end though it certainly amounts to a lot of money. And contrary to popular belief a lot of people down here do appreciate it.
