Retired neurosurgeon and former 2016 Republican presidential candidate Ben Carson has opted against accepting a cabinet position in the Trump administration, his spokesman said on Tuesday.

Carson has been a close adviser to Trump and is a vice chairman of his transition team.

He has been mentioned as a possible secretary of health and human services or education.

Carson's business manager, Armstrong Williams, said Carson has made clear he has no experience in running a federal bureaucracy.

"Dr. Carson feels he has no government experience, he's never run a federal agency. The last thing he would want to do was take a position that could cripple the presidency," he said, according to The Hill

Carson will continue to advise Trump in an unofficial capacity, Williams reportedly said.
