About 1.5 percent of the $1.6 billion awarded by the Federal Emergency Management Agency has gone to minority businesses, less than a third of the 5 percent normally required.

On Tuesday, Sen. Olympia J. Snowe, R-Maine, and Rep. Donald A. Manzullo, R-Ill., asked the Government Accountability Office to investigate whether small and minority-owned businesses have been given a fair opportunity to compete for Katrina contracts.

Andrew Jenkins doesn't think so.

Once Katrina's destructive waters receded, he began making calls in hopes of winning a government contract for his Mississippi construction company.

Jenkins, who is black, says he watched in frustration as the contracts went to others, many of them larger, white-owned companies with political ties to Washington.

"That just doesn't smell right," said Jenkins, president of AJA Management and Technical Services Inc. of Jackson, Miss., noting the region has a higher percentage of blacks and minority-owned businesses than other areas of the country.

To speed aid, many requirements normally attached to government contracting were waived by Congress and the administration. The result has been far more no-bid contracts going to businesses that have an existing relationship with the government.

There also was an easing of  affirmative action rules for contractors and a suspension of a "prevailing wage" law that black lawmakers and business people believe will hurt the disproportionately large number of black hourly workers in the region.

"It sends a bad message," said Harry Alford, president of the National Black Chamber of Commerce. "What they're basically saying to the minority in New Orleans is, 'We'll make it harder for you to find a job. And if you do, we'll make sure you get paid less.'"
