A former public official sent to prison for corruption is now getting stimulus money for a Louisiana sidewalk project. A newspaper investigation uncovers shoddy work in Ohio’s weatherization program. And the government’s housing watchdog raises questions about a Pittsburgh nonprofit’s application for lead paint removal.

These are among the cases we’ve added to our stimulus investigations chart.

The chart, which we’re updating regularly, tracks inspector general reports, auditor investigations and news accounts about questionable contractors. If you have new information about a case or know one we should add, e-mail it to [email protected].
