NEW: Socialist Bernie Sanders says he has to spend $221,000 on private jets to "fight the oligarchy," scoffs at the thought of flying on a commercial plane.

Baier: You spent 221,000 on private jets fighting the oligarchy tour, paid for by friends of Bernie Sanders

Sanders: When's the last time you saw Donald Trump during a campaign mode at National Airport?

Baier: He's also not 'fighting the oligarchy.'

Sanders: You think I'm going to be sitting in a waiting line at United? ... That's the only way you can get around. No apologies for that.

Total scammer.
