NASHVILLE (AP) — The Tennessee Bureau of Investigation is looking into Nashville District Attorney Glenn Funk's enrollment in the state pension plan before taking office.

WTVF-TV and The Tennessean report that TBI special agents were requested by Attorney General Herbert H. Slatery III and have begun investigating Funk's employment in a part-time job before becoming D.A. and state benefits.

The Tennessee District Attorneys General Conference hired Funk to work as a prosecutor after he was elected but before he was sworn in. That allowed him to enroll in the retirement system before employee contributions increased.

The conference's executive director was suspended and resigned. Funk has said he will return state money and adjust his retirement plan.
