Three Presidents and a First Lady

President Barack Obama, former President Jimmy Carter, first lady Michelle Obama, and former President Bill Clinton celebrated the 50th anniversary of the March on Washington in front of the Lincoln Memorial.
"On a hot summer day, they assembled here, in our nation’s capital, under the shadow of the Great Emancipator — to offer testimony of injustice, to petition their government for redress and to awaken America’s long-slumbering conscience," President Obama said of the marchers.
