A Drug Enforcement Administration (DEA) group supervisor had an “improper personal relationship” with a confidential source and approved payments to the source without justification, according to a report from the Justice Department’s Office of Inspector General.

The Department of Justice (DOJ) watchdog started the investigation following a tip from the DEA’s Office of Professional Responsibility saying the unnamed supervisor both made the unjustified payments and “caused false statements to be made” to justify them.

The report also found the supervisor misused their government vehicle to take the source on dates and shared nonpublic information relating to personnel matters within the DEA, and that their then-supervising DEA assistant special agent in charge (ASAC) authorized the payments.

The probe also found the source went on two personal trips with the supervisor and the supervisor allowed the source to accompany them on visits to the supervisor’s family and friends, none of whom were made aware that they were a DEA source.

“The OIG concluded that the GS violated DEA policy and federal law when the GS approved payments to the CS without proper justification and when the GS approved a form relating to the CS knowing that it included false statements,” the report states.

“Further, the OIG concluded that the ASAC failed to properly supervise the GS,” the OIG summary adds.

While the OIG found the conduct was a violation of DEA policy and federal law, criminal prosecution was declined.
