WASHINGTON (AP) - President Barack Obama says slavery is a terrible part of the United States' history and should be taught in a way that connects it to current events.
Obama compared the legacy of slavery to the history of the Holocaust. He said both are horrible parts of history that cannot be ignored. He said in a CNN interview that their lessons must never be forgotten and applied to current situations in Darfur and Congo.
Obama returned to Washington early Sunday morning from a trip that took him to Russia, Italy and Ghana. It was the first trip to sub-Saharan Africa for America's first black president.
Obama and his family visited a West African castle where traders once shipped slaves to the New World.
Obama was interviewed Saturday for CNN's "Anderson Cooper: 360." A brief excerpt was released on Sunday.
