(Washington, DC) -- President Obama is calling for reflection and understanding in remembering a St. Louis-area teen who was shot to death by police last weekend. In a statement on Tuesday, Obama called the death of Michael Brown "heartbreaking." The President said the Department of Justice is investigating. The Reverend Al Sharpton is in Ferguson, Missouri to offer support for Brown's family and to try to bring calm to the city. Tuesday afternoon, the civil rights leader said protesters who responded to the deadly shooting with violence are dragging Brown's name "through the mud."
