Republican presidential nominee Donald Trump’s first wife, Ivana, says her ex-husband can be a big baby who cannot stand to be bested in public in an interview released with just 12 days to go until Election Day.

In an interview with Trump biographer Michael D’Antonio, Ivana Trump recounted an incident from their courtship, a ski trip to Colorado. She had not told the real estate mogul she was an accomplished skier.

Trump skied down first.

“So he goes and stops, and he says, ‘Come on, baby. Come on, baby,’ “ Ivana Trump said. “I went up. I went two flips up in the air, two flips in front of him. I disappeared. Donald was so angry, he took off his skis, his ski boots, and walked up to the restaurant. ... He could not take it. He could not take it.”

She said he stormed off, muttering, “I’m not going to do this for anybody, including Ivana.”

The interview was among those conducted with Trump and his three oldest children in 2014 for “The Truth About Trump.” Tapes of the interviews were made available to the New York Times and CNN. D’Antonio initially offered the tapes to the Clinton campaign, but the Democrats showed little interest.

The Trump campaign issued a statement Monday calling the tapes pretty old.

The tapes shed light on the disputes Trump has sparked during the campaign, including spats with Fox News host Megyn Kelly, whom he suggested was menstruating after she pressed him on his views about women during a Republican primary debate, and the Khan family, whose son was killed as he served in the U.S. military in Iraq, after Khizr Khan criticized Trump at the Democratic National Convention.

Trump told D’Antonio he’s always relished a good fight, describing himself as a rebellious youth.

“I loved to fight. I always loved to fight,” Trump told the interviewer, adding, “All types of fights. Any kind of fight, I loved it, including physical.”

The behavior got him sent to the New York Military Academy at age 13, indicating he was physically punished when he mouthed off to a drill instructor. But he loved it. “It was fantastic,” he said.

Trump also said he had been hooked on seeing his name in print since he was mentioned in a newspaper story for his performance as a high school baseball player. He also realized how to use the media to promote his business ventures without having to buy advertising time or space.

Trump said he doesn’t engage in introspection: “I don’t like to analyze myself because I might not like what I see.”

He also said he doesn’t have any heroes and doesn’t like to talk about the past. Additionally, Trump said he “never had a failure” despite his bankruptcies.
