The Clinton administration on Friday proposed regulations that would disqualify companies with inconsistent records on federal environmental, labor, and tax laws from winning government contracts. The regulations now face a 120-day public review period, and the business community is mounting a major effort to stop the rules from taking effect. Congressional Republicans are siding with business against the regulations. Randy Johnson, a vice president with the U.S. Chamber of Commerce, said the chamber will press Congress to attach a rider to an appropriations bill that would prohibit the administration from using federal funds to implement the rules.
