Obama is calling his visit to a Senegalese island from which Africans were said to have been shipped across the Atlantic Ocean into slavery, a 'very powerful moment.' President Obama was in Dakar Thursday as part of a weeklong trip to Africa, a three-country visit aimed at overcoming disappointment on the continent over the first black U.S. president's lack of personal engagement during his first term.
