Retired neurosurgeon Ben Carson, a confidant to President-elect Donald Trump since the end of the Republican primaries, says it is unlikely that he will join the administration but that he will remain an informal adviser.

“The way I’m leaning is to work from the outside and not from the inside,” Carson said in an interview Tuesday with The Washington Post. “I want to have the freedom to work on many issues and not be pigeonholed into one particular area.”

He has been under consideration for several positions in Trump’s Cabinet, including secretary of health and human services.

“I’ve said that if it came to a point where he absolutely needs me, I’d reconsider. But I don’t think that’s the situation with these positions,” Carson said.
