Drug Smuggling Air Marshals?

For a law enforcement agency that works hard to be invisible, the Federal Air Marshals have been generating a lot of attention lately. On Thursday, two of the agency's several thousand highly trained traveling armed guards were taken into custody in Houston. Although the US Attorney's office would not comment beyond acknowledging that the Air Marshals were arrested by agents from the Federal Bureau of Investigation and the Department of Homeland Security's Inspector General's office, Government sources tell TIME that the two Air Marshals, are allegedly involved with the possession or transportation of cocaine, and may have been paid several thousand dollars to move the drugs.
