A pouting Donald Trump said Friday that he may cancel his Republican presidential debate altogether after all but two candidates refused to participate.

"You know who I'm very disappointed [in]?" Trump asked Fox Business News's Don Imus. "Michele Bachmann. She came up to see me four times. Four times! She'd call me, she'd ask me for advice. She said I should be her vice presidential -- you know, if she wins [the nomination], she'd like to think about me for the vice president."

"And most importantly, I did like a two-hour phone call for her -- with her people, and it caused me certain problems. People said, 'Are you endorsing her?' The answer was no. And then after all of that, she just announced she's not going to do the debate. It's unbelievable! It's called loyalty. It's actually called loyalty. How do you do that?"

"I'm surprised you like [Newt] Gingrich," Imus noted. "He's really creepy."

"He's got courage," Trump replied.

"So, are you still going to do the debate with just Gingrich and Rick Santorum?" Imus wondered.

"I don't know," Trump admitted. "I have to look into it. I have to see. They really want me to drop my status as a potential person to run as an independent and, honestly, I don't think I'm going to do that."

Appearing on Fox News Thursday, Republican National Committee Chairman Reince Priebus said it was "a problem" that Trump wouldn't rule out an independent run, while at the same time moderating a GOP debate.

“[The] issue here is whether the moderator should still be a person who’s still batting around the idea of running as an independent,” the RNC chairman explained. “I think that should give some of these candidates some concern.”
