“It’s a very strange phenomenon,” he said on Fox News’s “The O’Reilly Factor” Monday. "We get along. I don’t know if he’ll admit this, but he likes me.”

“I like him because I can feel it,” Trump added of his predecessor, who leveled hash criticism against the businessman during the campaign. "That’s what I do in life — it’s called like, I understand.”

“Now we had a rough campaign. He was fighting better for Hillary than she did,” he said of Obama’s former secretary of State. "He was vicious during the campaign toward me, and I was vicious toward him.”

“We said horrible things about each other and then we hop in the car and we drive down Pennsylvania Avenue together. We don’t even talk about it,” Trump added of his Jan. 20 inauguration in Washington, D.C.

"Politics is amazing.”

Trump then revealed Obama considers “a military problem with a certain place” to be America’s greatest upcoming challenge. He refused to say more, but added that the former leader was not referencing China.

“I said, ‘What would you say the number one, two and three problems are?’” Trump recounted. "And the number one problem that he felt — I was a little bit surprised, but I fully understand why he said it.”

“I can’t do that, I can’t do that,” he added when O’Reilly urged him to reveal Obama’s specific concern. "I don’t think [Obama] would mind if I said it. I don’t want that particular place to know that that’s the way he or I feel.”

Trump repeatedly hammered Obama’s leadership during the 2016 race, challenging his handling of issues ranging from the economy to radical Islamic terrorism.

Obama endorsed Clinton over Trump, questioning Trump's temperament for the presidency and portraying him as a threat to his administration’s progressive accomplishments.
