A changing of the guard at the Small Business Administration has done little to lift the veil of secrecy surrounding government contract awards to small businesses. If anything, the SBA's stonewalling is even stronger, according to one group.

In the three months since taking office, SBA Administrator Steven Preston has rejected all requests – even from the media – to release a list of companies that have won federal contracts earmarked for small businesses, says Lloyd Chapman, founder and president of the American Small Business League.

Chapman has been waging a public campaign to force the SBA to follow up on government investigations that have documented hundreds of cases where small business contracts went to major corporations, from Lockheed Martin, Boeing, and General Dynamics to Microsoft and Wal-Mart.
