UNDATED (WKRC) -- The Republican field of candidates continues to widen. Retired neurosurgeon Dr. Ben Carson is expected to make a major announcement at an event tomorrow in his hometown of Detroit. But in an exclusive interview tonight, Dr. Carson tells our National Correspondent Jeff Barnd he is in the race for the White House in 2016. "I'm willing to be part of the equation and therefore, I'm announcing my candidacy for President of the United States of America." With that, Dr. Ben Carson is off and running. He rose from poverty in Detroit to the head of the pediatric neurosurgery at Johns Hopkins Hospital in Baltimore. He's now retired from medicine. "Many people have suggested to me that I should run for president, even though I'm not a politician," Carson said. Dr. Carson's political star rose at the National Prayer Breakfast two years ago when he admonished President Obama for several white house policies including Obamacare. "I began to ask myself why are people clamoring for me to do this? I represented a lot of the same thoughts that they have," Dr. Carson says. "I'm not 100% sure 'politics as usual' is going to save us. I think we are in a severe problema problematic situation." Dr. Carson's own words at times have caused controversy in recent months regarding Obamacare and homosexuality. "Now that you've announced you're running for President of the United States," Barnd asked, "what have you learned from those experiences?" "I don't wander off into those extraneous areas that can be exploited. I have learned that." Dr. Carson himself shuns political correctness and says today's society is too divisive. He calls himself "a reluctant warrior" and realizes he can't solve all the problems currently plaguing this country. "You must have enough humility to be able to work with others to recognize you're not necessarily the expert in everything. But you can with very good advice, make good decisions."Follow us on Twitter @Local12 and LIKE us on Facebook for updates!
