(CNSNews.com) - In a lengthy, taped interview that aired on Sunday, Fox News's Chris Wallace asked President Donald Trump some expected questions -- about the Mueller investigation, "fake news," the election, the Kashoggi murder, his divisive tone -- and then came something unexpected.



Wallace wondered if Trump would try to amend the Constitution so he could serve a third term.

The exchange began when Wallace asked the president to rank himself "in the pantheon of great presidents."



"There is Lincoln and Washington, there's FDR and Reagan. Do you make the top 10?" Wallace asked Trump.



"I think I'm doing a great job," Trump said. "I would give myself, I would -- look, I hate to do it, but I will do it. I would give myself an A-plus, is that enough? Can I go higher than that?"



Wallace followed up: "Can you envision a situation well into your second term where you think you're so good for the country and so essential to the progress of the country that you would try to amend the Constitution so you could serve a third term?"



"No, no," Trump responded.



"Why not?" Wallace asked.



"Just won't happen," Trump said. "It's not -- I think the eight-year limit is a good thing, not a bad thing."



Wallace's out-of-the-blue question about Trump changing the Constitution -- which he couldn't do even if he wanted to -- followed a somewhat testy exchange about "fake news." Notably, Wallace lumped himself in with the liberal media, saying he is "in solidarity" with CNN and "The New York Times."

First, Wallace complained about Trump calling the media the "enemy of the people."



Trump responded that there is a lot of "dishonest reporting."



"See, I know it, because I'm a subject of it," Trump said. "A lot of people don't know, but when I explain it to them, they understand it. And, Chris, you know that better, you don't have to sit here and act like a perfect little, wonderful, innocent angel. I know you too well, I knew your father too well, that's not your gene. But let me tell you --" Trump started to say.



Wallace interrupted him, admitting that some of the Trump coverage is "biased."



"Most of it is biased, most of it," Trump said, adding that he was not calling Wallace an enemy of the people.



"We're all together," Wallace said. "When you call CNN and "The New York Times" -- and we're in solidarity, sir," said Wallace.



"I am calling fake news, fake reporting -- is what's tearing this country apart because people know, people like things that are happening and they're not hearing about it," Trump said.
