BALTIMORE (WJZ) — According to WJZ’s media partner, the Baltimore Sun, Dr. Ben Carson is retiring.

“In 106 days, I will be retiring,” Carson said in a speech Saturday morning at the Conservative Political Action Conference.

A speech that he gave recently went viral. He spoke about the need for a flat income tax–which he compared to tithing–in the speech, which led to many conservatives calling on him to run for office.

Carson refused to discuss whether he would enter politics after he retires from Hopkins.

Carson was the first surgeon to separate conjoined twins and was the subject of a TV movie. He received the Medal of Freedom in 2008.

Carson is 61 years old and is the head of Hopkins’ pediatric neurosurgery department.
