Donald Trump Ends Fox News Boycott, Now Goes to War With 'Forbes'

Donald Trump ended his boycott of Fox News after six days and appeared on 'The O'Reilly Factor.'

Donald Trump's boycott of Fox News is over -- just six days after saying he wouldn't appear for the "foreseeable future" because he was being treated "very unfairly."

Trump told Bill O'Reilly: "You've always been fair to me, Bill. I've never had a problem with you. You've always treated me with respect and fairly."

The host then warned the billionaire: "Well, that's gonna change tonight."

O'Reilly asked Trump about the shot he took at Republican rival Marco Rubio that received boos last week. He told a crowd that Rubio is "a clown."

Trump walked back the comment Tuesday night – kind of.

O'Reilly told Trump: "Calling him a 'clown,' that's not presidential."

Trump seemed to get upset and said: "Okay listen, okay, excuse me Bill. He was a member of the 'gang of eight,' which was a disaster, he was totally weak on immigration and, by the way, he hasn't changed."

"That's fine; it's the 'clown' stuff that's not fine. Last question," said the host.

"Well, okay, I can understand that," said Trump.

And it's another day another feud. Trump is now on the warpath with Forbes magazine -- which just unveiled its annual list of the 400 wealthiest Americans.

Forbes says Trump's net worth is $4.5 billion not the $10 billion-plus he claims.

But Trump is firing back, telling the magazine: "Look, all I can say is Forbes is a bankrupt magazine, doesn't know what they're talking about. It's embarrassing to me."

Trump is also on the cover of the new People magazine -- along with wife Melania and his youngest child, nine-year-old Barron.

In her first major interview since Trump declared he was going to run for president, Melania says she's optimistic that her husband can win.

She told the magazine: "It's a long road. I take it day by day. My husband has a lot of people cheering for him. We will see."
