Tens of thousands of Americans are expected to gather at the Lincoln Memorial in Washington, D.C., today to commemorate 50 years since Rev. Martin Luther King Jr. made his "I Have a Dream" speech.

Tens of thousands of people marched to the Martin Luther King Memorial in Washington yesterday commemorating the 50th anniversary of his "I Have a Dream" speech.
But there was a strong theme of unfinished business, with speakers lamenting what they see as new attacks on civil rights.
"This is not the time for nostalgic commemoration," said Martin Luther King III, the oldest son of the murdered civil rights leader.
"Nor is this the time for self-congratulatory celebration. The task is not done. The journey is not complete. We can and we must do more."

And in an exclusive interview with ITV, Congressman John Lewis, who was a young speaker at the foot of the Lincoln Memorial during the march on Washington, recalled those heady days of 1963.
He talked about the racial tensions that still exist in the US, but also his hopes for the future, and for what Martin Luther King described as the "beloved Community" of whites, blacks, latinos, asians and peoples of all races.
The 50th anniversary of Martin Luther King's 'I have a dream' speech will be celebrated next week.
