Vice President Joe Biden was to announce the list Friday as part of an effort to cut down on waste and fraud.
The "do not pay" list is meant to keep benefit checks, grants and contract money from going to people who don't qualify. For example, it targets companies that have been barred from government projects.
Other efforts include a new online fraud-detection tool to keep tabs on the administration's stimulus plan. In a new pilot program, it'll be used by the agency that runs Medicare and Medicaid.
