Clinton apologized personally to Obama for Shaheen’s remarks at Reagan National Airport before they headed for today's debate in Iowa. "I deeply regret my comments yesterday and say again that they were in no way authorized by Senator Clinton or the Clinton campaign … I made a mistake and in light of what happened, I have made the personal decision that I will step down as the co-chair of the Hillary for President campaign," Shaheen said in a statement.
