Trump took the witness stand Tuesday at a civil trial where the developer-turned-TV personality is accused of wooing investors into buying condos at his namesake Chicago skyscraper by promising profit-sharing, then reneging on that promise after the sales.
Plaintiff's attorney Shelly Kulwin sought to establish that Trump was a hands-on manager, while Trump said he was a big-picture executive.
"The primary thing is to build a great building," Trump told jurors, leaning into a microphone and speaking calmly and steadily. "You can't fool people."
"That's an interesting infomercial," Kulwin responded. The attorney later told the judge that Trump wasn't answering his questions, saying "he's giving a speech."
Both sides have said Trump's testimony is key to the trial's outcome and so he could remain on the stand for days talking about the development of his glitzy Trump International Hotel & Tower.
The trial stems from a lawsuit filed by Jacqueline Goldberg, 87, who in 2006 agreed to buy two condos for around $1 million apiece at the 92-story luxury building. It boasts more than 300 hotel rooms and nearly 500 condominiums in a prime location - along the Chicago River and just two blocks from Michigan Avenue.
The lawsuit that alleges breach of contract and deceptive practices seeks the return of a $500,000 deposit Goldberg made for the properties and other unspecified damages.
Goldberg's lawyer portrayed the sale of the condos to his client as a bait-and-switch, where Trump and his executives sought to make the properties more attractive investments by telling would-be buyers they would reap a percentage of profits from banquet hall rentals, food sales, laundry, parking and other services.
Trump's stardom and real estate successes were also touted in condo sales pitches.
"'Who better to go into the hotel business with than Donald Trump?' she thought," Kulwin told jurors during opening statements Monday.
One reason Trump summarily canceled the profit-sharing plan, Kulwin said, was because he had failed to entice a corporate tenant to rent several floors of the building - cutting into the tower's potential profit. The profit he had promised to make condos a more attractive investment he now needed for himself, Kulwin said.
By the time Goldberg went ahead with her purchase in 2006, Kulwin alleged, Trump and other executives already knew the profit-sharing offer would be withdrawn. It was only formally withdrawn in 2009, however, a few months before the tower's grand opening, he said.
"They made a deal and then they said, 'Surprise! No deal,'" he said.
But Trump attorney Stephen Novack said Goldberg was a sophisticated, longtime investor who signed documents explicitly giving Trump executives the power to revoke the profit-sharing offer if they saw fit.
In an apparent bid to deflect any blame from Trump himself, Novack in his opening statement also sought to counter the plaintiff's portrayal of Trump as a hands-on executive.
"Donald Trump delegates most decisions," Novack said, noting he had 2,500 employees. "It would be impossible for him to be in the details of each project."
He insisted the decision to change the profit-sharing provision was someone else's and it was one that Trump only agreed to later.
