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.
A report, conducted by the Interior Department's inspector general and released earlier this month, found that employees at the agency received improper gifts from energy industry officials and engaged with them in illegal drug use and inappropriate sexual relations. It looked at activities at the agency from 2003 through 2006.
Maxwell said the report doesn't surprise him. The agency, he said, is corrupt "top to bottom." Watch a failure to "protect America's interests" »
"It sounds like they forgot they work for the government," he said. "It's disgusting. ... There's no excuse for that. Those people should not be working in those positions at all.
"They crossed a lot of lines that should never have been crossed," he said. "They lost all objectivity."
