MLK's 9-year-old granddaughter, Yolanda Renee King, rallies crowd at March for Our Lives

WASHINGTON — Yolanda Renee King, the nine-year-old granddaughter of the Rev. Martin Luther King Jr. and daughter of Martin Luther King Jr III, took the stage in Washington Saturday to deliver a message at the March for Our Lives rally.

"My grandfather had a dream that his four little children would not be judged by the color of their skin but by the content of their character," she told the crowd. "I have a dream that enough is enough."

She then led in chanting: "Spread the word. Have you heard. All across the nation. We are going to be. A great generation"

“All of these movements are leading to change in this great country,” he said, noting that soon these youth will be of voting age.

King III, in a CNN interview with his daughter, talked about the power of this movement and others in recent years, such as Black Lives Matter.

“The best is yet to come,” he said.
