Trump campaign national spokeswoman Katrina Pierson tells MSNBC's Steve Kornacki the Republican presidential frontrunner did not blame President George W. Bush for 9/11, but said he did not keep the country safe.



"Donald Trump didn't say that the Twin Towers coming down was George Bush's fault," Pierson said. "He said George Bush didn't keep safe, and there are thousands of families that would agree with that. But I will have to define safe for you. Donald Trump's measure of safety is very different than the Bush's. Donald Trump wants a border wall. He wants to stop illegal immigration. He wants to deport illegal aliens. There are a number of things that Donald Trump would determine safe that the Bushes just didn't quite agree at that time."



Pierson said some of the 9/11 highjackers did flight training in Florida while Jeb Bush was governor.



"You say he's not blaming George W. Bush, but he is saying that George W. Bush didn't keep us safe. So it sounds like he is saying, there are things that George W. Bush could and should have done that would have prevented the Twin Towers from falling," Kornacki said to Pierson.



"Well, we don't know for sure if it could have been prevented, but what we do know is that the hijackers did come into this country on visas from hostile territories," Trump's spokeswoman said. "We know that one was here on an expired visa and we know they trained in Florida under Jeb Bush's watch to take down those towers."



"We were not tracking those people and that's a problem. That's one of the reasons Donald Trump got into this race, protecting our sovereignty from radical Islamic extremists. So to Donald Trump's point of safety, he's absolutely right," Pierson told MSNBC.
