Republican candidate Donald Trump has claimed the 9/11 attacks would not have happened if he had been president. Speaking on Fox News Sunday, Trump said his tough immigration policies would have stopped the hijackers.

Donald Trump: “I am extremely, extremely tough on illegal immigration. I’m extremely tough on people coming into this country. I believe that if I were running things, I doubt those families would have—I doubt that those people would have been in the country. So there is a good chance that those people would not have been in our country. With that being said, I’m not blaming George Bush, but I don’t want Jeb Bush to say, 'My brother kept us safe,' because September 11 was one of the worst days in the history of this country.”
