President Obama speaks on the 50th Anniversary of Martin Luther King Jr's "I Have A Dream" speech

From USA Today:

In his address to thousands who gathered on the Washington Mall on Wednesday to mark the 50th anniversary of the March on Washington, President Obama paid tribute to civil rights leader Martin Luther King Jr. and to the anonymous millions who stood by King's side during the civil rights fight of the 1960s.

Obama remembered those who could not marry the ones they loved because of so-called anti-miscegenation laws, African-American soldiers who fought for freedom abroad that they could not enjoy on U.S. soil and white Americans who could not stand by discrimination and sacrificed sometimes with their own blood.

"Because they marched, America became more free and more fair," Obama said. "Not just for African-Americans but for women and Latinos, Asians and Native Americans, for Catholics, Jews and Muslims, for gays, for Americans with disabilities. America changed for you and for me. And the entire word drew strength from that example."

Before Obama took the stage on Wednesday, former presidents Jimmy Carter and Bill Clinton offered stirring tributes to King.
