The Associated Press reports that “The company with the biggest share of contracts is under a federal investigation into possible criminal violations involving its oversight of background checks, officials familiar with the matter told The Associated Press. They spoke on condition of anonymity because they were not authorized to discuss the investigation.”

“Even with fresh congressional scrutiny, the federal government appears wedded to the incumbent screening system. Nearly three-quarters of the government’s background checks are done by private companies, and of those, more than 45 percent are handled by the U.S. Investigations Services, or USIS, according to the U.S. Office of Personnel Management, the agency overseeing most of the government’s background checks.”

“USIS, which started out with 700 former government employees in 1996 and is now run by a private equity fund, dominates the background check industry, taking in $195 million in government payments last year and more than $215 million already this year.”
