Whistleblower: Oil watchdog agency 'cult of corruption'

HONOLULU, Hawaii (CNN) -- Bobby Maxwell kept a close eye on the oil industry for more than 20 years as a government auditor. But he said the federal agency he worked for is now a "cult of corruption" -- a claim backed up by a recent government report.

"I believe the management we were under was showing favoritism to the oil industry," Maxwell told CNN.

Maxwell is referring to a tiny agency within the Department of the Interior called the Minerals Management Service, which manages the nation's natural gas, oil and other mineral resources on federal lands.
