After OFI became USIS, the timeliness and quality of the security background checks conducted on Federal employees quickly deteriorated according to former OFI employees. They saw USIS being turned into a cash laundering operation whereby a few officials at the top became instant millionaires. Insiders also report that USIS "branched" into other operations never before conducted by OFI/OPM. These other operations were the focus of Col. Ted Westhusing's investigation when he was "suicided" in Baghdad. It is also noteworthy that USIS assumed control of a converted limestone mine in Boyers, Pennsylvania. The mine, built during the Cold War to safeguard files in the event of a nuclear conflict, contains millions of government files, including those held by the federal Employee Service and Records Center. That means that The Carlyle Group now has access to sensitive personnel files on millions of current and past government employees as well as contractors who have applied for security clearances.
