Colorado Chief Medical Officer Resigns

DENVER (AP) — Colorado's chief medical officer is resigning, less than a week after the release of a state report raising questions about a laboratory under his supervision.

Gov. John Hickenlooper announced the resignation Thursday. Dr. Chris Urbina is executive director of Colorado's Department of Public Health and Environment.

A March report from an employee consulting firm said some workers of the lab at CDPHE complained that a supervisor made statements suggesting a bias in favor of prosecutors. The state released the report last week. Urbina said the supervisor was later reassigned.

Defense attorney said the report raised the possibility of thousands of appeals to drunken-driving convictions.

Hickenlooper's spokesman Eric Brown said in an email he didn't "have anything to add to what's in the press release."
