Donald Trump Isn't Ruling Out Independent Run

Republican presidential candidate says he wants to be treated "fairly."

Trump has previously cited "fairness" as a reason he would run a third-party bid. In September, when he signed the pledge, he said he gained nothing besides "assurance that I’ll be treated fairly.”

Trump pointed out that he’s currently content with his position in the polls.

“I’m leading every poll by a lot,” Trump said. “It’s not even a little bit anymore -- it’s a lot.”

Trump also targeted Hillary Clinton, a potential rival in the general election, saying she didn't "have the strength or the stamina" to be president.

"She's not a strong enough person to be president," he said.
