The 21st century looks different. It's been very disruptive. It has created a lot of insecurity. We have to adjust to that, because the 21st century has real promise.

Barack Obama doesn't believe in free enterprise. He's never going to admit it. For instance, he's never going to come straight out and say, 'If you own a business you didn't build it.' Alright, maybe he will.

Obviously I don't agree with everything he [Donald Trump] says. There's a lot that we have a difference of opinion on.
