In a press conference following a rally in Nevada today, presidential candidate Ben Carson told reporters that he saw a video of American Muslims cheering on Sept. 11, 2001, in New Jersey when the World Trade Center’s twin towers fell.

When asked by ABC News if American Muslims were cheering on 9/11, Carson said “Yes.”

When asked if he specifically saw it happening he said, “I saw the film of it, yeah.”

Later in the press conference he clarified he saw it from “the newsreels” from the 9/11 coverage at the time.
