ADDING SECOND SENTENCE TO CAPTION - Attorney General Eric Holder acknowledges applause before speaking at a rally to commemorate the 50th anniversary of the 1963 March on Washington on the steps of the Lincoln Memorial in Washington Saturday, Aug. 24, 2013. Holder, the nation's first black attorney general, said he would not be in office, nor would Barack Obama be president, without those who marched. "They marched in spite of animosity, oppression and brutality because they believed in the greatness of what this nation could become and despaired of the founding promises not kept," Holder said.
