Former New York City Mayor Rudolph Giuliani introduced Trump onstage in Youngstown on Monday, where Giuliani sparked outrage when he appeared to momentarily forget about the events of 9/11.

Rudolph Giuliani: “By the way, under those eight years before Obama came along, we didn’t have any successful radical Islamic terrorist attack in the United States. They all started when Clinton and Obama got into office.”

That was Rudolph Giuliani, who was mayor of New York City during the 9/11 attacks. In response,the cover of the New York Daily News today printed Giuliani’s words superimposed upon an image of the falling twin towers.
