"I can relate to Martin Luther King probably the most because we haven't carved him in marble yet. He's still a man, and that's the message," said Beck.
Beck said he wanted to recognize America's military and their families.
Some civil rights leaders said he was sending the wrong message.
They want to disgrace this day, and we not giving them this day, this is our day and we're not giving it away," said the Rev. Al Sharpton of the National Action Network.
Sharpton and others held a "Reclaim the Dream" rally at a nearby Washington DC high school. They said Beck's rally was anti-government, and that it's timing was disrespectful.
