The nine-year-old granddaughter of Martin Luther King Jr. made a rousing appearance at a huge protest for gun control in Washington on Saturday, saying that like the slain civil rights leader she too has a dream -- "a gun-free world."
The poised young girl made a surprise appearance at the "March For Our Lives" rally, held near the National Mall where her grandfather delivered his "I Have a Dream" speech calling for an end to racism in the United States in August 1963.
