(CBS News) Dr. Ben Carson was already a world-renowned doctor when he was invited to speak at a Washington, D.C. panel a week ago. But he was launched into the political spotlight — and perked the ears of conservatives — when he spoke out against President Obama’s health care and economic policies with the president just feet away.

In an exclusive interview with CBS Baltimore WJZ, the neurosurgeon responded to speculation about his political future and what he plans on doing when he retires from Johns Hopkins in four months.

Although Republicans have expressed a lot of support, Carson said he doesn’t align himself with a political party.

“I call myself a logical person,” Carson told WJZ-TV’s Adam May. “I happen to be an independent — registered as an independent — but anything I talk about or advocate, I would challenge anybody to show me where it’s not logical.”
