(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.

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."
