Photos show thousands rallying in Washington for racial justice on the 57th anniversary of MLK's 'I Have a Dream' speech

• Large crowds gathered on Friday for the "Get Your Knee Off Our Necks" rally for racial justice in Washington, DC.
• The march came on the 57th anniversary of Martin Luther King Jr.'s 1963 "I Have a Dream" speech.
• Speakers included prominent Black leaders, activists, lawmakers, and people whose relatives have been injured or killed by police violence.

Large crowds of thousands of protesters rallied in Washington, DC, on Friday for the "Get Your Knee Off Our Necks" march against police brutality and racial injustice.

The event, organized by the National Action Network, came on the 57th anniversary of the 1963 March on Washington for Jobs and Freedom, where Martin Luther King Jr. delivered his famous "I Have a Dream" speech.

"The objective is to put on one platform, in the shadow of Abe Lincoln, the families of people that ... have lost loved ones in unchecked racial bias," Rev. Al Sharpton, founder of the National Action Network and one of the key organizers of the event, told the Associated Press."On these steps, Dr. King talked about his dream, and the dream is unfulfilled. This is the Exhibit A of that not being fulfilled."

The event came amid civil unrest across the country after the police shooting of Jacob Blake in Kenosha, Wisconsin. It also came on the heels of the death of George Floyd in Minneapolis who died when an officer knelt on his neck, and several months after the fatal shooting of Breonna Taylor in Louisville, Kentucky.

The NAACP organized a 2020 Virtual March on Washington Thursday and Friday. Stacey Abrams, Nancy Pelosi, Cory Booker, and Rev. Dr. William J. Barber II were among those who spoke at the virtual event.

George Floyd's sister, Bridgett Floyd, urged people to fight injustice for future generations, and not to become complacent. "My brother cannot be a voice today. We have to be that voice. We have to be the change, and we have to be his legacy. Thank you, from the Floyd family," she said.

The mother of Ahmaud Arbery asked people to "say his name" and "please let their names live forever." Arbery was fatally shot in February after being pursued by armed white men attempting to make a citizen's arrest.
