Thousands gathered at the National Mall Saturday to commemorate the 50th anniversary of the March on Washington. Speakers including Martin Luther King III and Democratic Rep. John Lewis, who was the youngest speaker at the 1963 march, encouraged the crowd to continue fighting for social justice. Attorney General Eric Holder kicked off the celebration, acknowledging the work of civil rights leaders from the Martin Luther King, Jr. era.

“But for them, I would not be Attorney General of the United States and Barack Obama would not President of the United States of America,” Holder said.

The president will deliver an address from the Lincoln Memorial Thursday at 3 p.m., the exact hour King gave his landmark “I Have a Dream” speech.
