Video: Trump Biographer Says President 'Tried to Show Me These Bone Spurs. I Didn't See Anything'

Yesterday, The New York Times published a report outlining claims from the daughters of a New York podiatrist who said that Donald Trump's medical diagnosis of bone spurs—which allowed the then 22-year-old to avoid the Vietnam War draft—was granted as a favor to his father, Fred Trump.

Then on Wednesday night, Trump biographer Michael D'Antonio told CNN's Don Lemon that he believed the claims of the daughters, while also revealing the strange moment when the President allegedly tried to show him what he thought were the bone spurs.

"I'm not even sure actually that the president knows the truth about this," D'Antonio told Lemon. "This is the odd thing: He may have been examined. He took off his shoes and tried to show me these bone spurs. I didn't see anything.

"This is the problem with the president; that so many of his biographical details are hazy, and in this case, I believe these women, I don't think there ever was a medical issue," he said.

In the Times article, one of the daughters, Elysa Braunstein, said that her father gave Donald Trump the diagnosis of bone spurs in exchange for preferential treatment as a tenant in a building where Fred Trump—a real-estate mogul—was the landlord. The foot doctor, Larry Braunstein, also recalled helping the Trump family on other occasions during the Vietnam War in the late 1960s.

"I know it was a favor," Braunstein told the Times. "If there was anything wrong in the building, my dad would call and [Fred] Trump would take care of it immediately," she said.

D'Antonio said he was inclined to believe the story because the Trump family were fond of using favors.

"The Trump's have forever dealt in favors: You do something for me, I do something for you," he told Lemon. "These daughters of this podiatrist talked about how forever more, he was able to call up and maybe talk about the rent not going up so quickly and get a repair made here and an adjustment made there. Fred Trump was good to people who were good to him."

If it was done as a favor, it's possible that even the President himself doesn't actually know the truth, according to D'Antonio.

The biographer went on to contrast the current situation in which the president's immigration policies are harming parents trying to enter the U.S. who are simply trying to do the best for their children, with how Fred Trump was trying to help his own son by getting him out of the Vietnam draft.

"The irony here is that Fred Trump was trying to do something for his son," D'Antonio said. "Donald was not a conscientious objector, but he really did not want to serve and he was like millions of other young men during the Vietnam War who tried whatever they could do to get out of their service. Now we have a situation where all these parents are trekking across Latin America trying to get their kids out of harm's way and now they're in custody in United States facilities."
