While introducing Donald Trump at an event in Ocala, Florida Wednesday afternoon, former New York Mayor Rudy Giuliani to a blatant lie when he insisted the Hillary Clinton was lying about her reaction to 9/11 terrorist attacks.

“Don’t tell me if you said that you remember Sept. 11, 2001,” Giuliani said. “I remember Sept. 11, 2001. Yes, yes, you helped to get benefits for the people who were injured that day. But I heard her say that she was there that day. I was there that day, I don’t remember seeing Hillary Clinton there. That was like when she said she had to run through gunfire. That turned out to be, what do we call it? A lie.”

In reality, Clinton, who was the Democratic U.S. senator from New York at the time, is seen in a picture walking next to Giuliani and Gov. George Pataki only 24 hours after the attacks. There is also no record of Clinton saying she was at Ground Zero on the day of the attacks, according to Think Progress.

“But don’t tell me that you subscribe to the notion that all of us who were there on Sept. 11, and we’re lucky to have been alive and lost so many friends,” Giuliani said. “I lost so many friends on Sept. 11, I think about it every day. Don’t tell me you belong to our very, very tight group of ‘never forget.’ Don’t tell me that.”
