WASHINGTON - The Senate passed a resolution Thursday calling on the U.S. to apologize officially for the enslavement and segregation of millions of African-Americans and to acknowledge "the fundamental injustice, brutality, and inhumanity of slavery and Jim Crow laws."

The resolution, sponsored with little fanfare by Sen. Tom Harkin, D-Iowa, passed on a voice vote. It now moves to the House of Representatives, where it may meet an unlikely foe: members of the Congressional Black Caucus.
