The son of Dr. Martin Luther King Jr. is in the Twin Cities today to mark his late father's birthday, and to spread a message of diversity. Martin Luther King THE THIRD is the second oldest of the four children of the late Dr. King and Coretta Scott King, and he continues to carry out his father's work in civil rights by leading "Americans United for Affirmative Action" based in Atlanta. I asked him what he thinks of the way America celebrates the holiday named in honor of his father.
