It's been over three years since Hurricane Katrina hit, and still there are some 28,000 people receiving free rent and assistance from a guilty-feeling federal government. But not for long. Housing Secretary Steve Preston, asked how long the feds are planning to pay, says: "That's a great question, and that's an important point of conversation right now." At issue is the rental assistance aid that ends in February. Recipients are being advised on what federal programs they can apply to for further help. In the end, only 4,000 are expected to get aid.
