In his 2013 National Prayer Breakfast speech, Dr. Ben Carson made several remarks that the media widely interpreted as insulting to President Barack Obama, who was seated nearby on the speaker's dais. Carson claims that event organizers later told him that Obama wanted an apology.
During the speech, Carson criticized political correctness, moral decay, the Affordable Care Act, and the government's role in increased national debt. He suggested simplifying the tax code, replacing it with something similar to the biblical tithe.
While there is no verification other than Carson's claim that his speech offended the president, and Carson denies he intended direct insult, the allegation catapulted Carson into the national spotlight. Overnight he became a prominent conservative voice, ultimately using his fame to become a major contender for the 2016 Republican presidential nomination.
