Donald Trump may be the most highly-recognizable Republican Presidential candidate in modern history - but what do you really know about him?  As the guest on this episode of Greta Talk, the world-famous billionaire opens up about where he learned his business skills, and the importance of having - and being - a brand. He's passionate about his patriotism, including those who fought for our country.

Listen as Greta van Susteren asks the man who made the phrase "you're fired!" a national catch-phrase whether HE has ever been fired. And if that's not enough... catch his response to her question about his hair, and why it looks the way it does. Was he a hippie back in the day?  And you'll be fascinated by what he says he would install in the White House if he wins the Presidency.

It's not all fun and games, though, as the host of On the Record gets Trump to to talk about his own upbringing, what he's had to give up to run for President, and why he believes the middle class could become virtually extinct.

Don't miss this chance to peer into the "other" side of this unique man.
