Celebrations of the historic March on Washington begin on Wednesday, and will stretch through the 50th anniversary of Dr. Martin Luther King Jr.'s "I have a dream" speech, delivered on August 28th, 1963.
A half-century later, one of the "four little children" whom Dr. King had hoped would one day be judged not by the color of his skin but by the content of his character, says his father's vision has not yet been realized.
Citing June's Supreme Court ruling that struck down a key provision of the Voting Rights Act and the shooting death of Trayvon Martin, Martin Luther King III said on NewsNation Wednesday that it's clear "we've just got more work to do."
