presidents over these years here in washington. i don't remember a president of the united states having an exchange like this, simply going off the rails. he certainly does not like to admit he made a mistake. he certainly does not apologize. but this was certainly something i haven't seen. i don't remember a time when a president has done something like this, especially when you're dealing with neo-nazis, kkk supporters, white supremacists. this was an extraordinary moment, i must say. all right, jim accosta, thanks very much. i want to get reaction now from the former president and ceo of the naacp, our cnn contributor cornell william brooks. you must have been pretty shocked listening to the president. >> shocked, disturbed, unsettled. this president, in the 200 plus days he's been in office, 200 days ago, 200 plus days ago, he took an oath of office. he has yet to assume the moral gravitas of the office.
