Trump’s former business partner warns his 'temper, bluster and racial rhetoric’ will 'risk permanent damage'

A former business partner begged Americans not to vote for Donald Trump -- who he described as unfit for office.

Phil Satre, writing in the Reno Gazette-Journal, recalled his time as a senior vice president for Harrah's 34 years ago, when the casino company entered a joint venture with Trump at his Atlantic City hotel.

"Over a period of four years I met with Donald frequently, often multiple times a month," Satre wrote. "It was not a happy marriage, and it ended badly. Before the divorce, I had ample opportunity to form an opinion of him — an opinion that leaves me appalled by the very thought he could become our president."

Within a year of the joint venture, Harrah's was involved in a lawsuit with Trump, who claimed the casino company had mismanaged the project -- and Satre said the real estate developer displayed the same negative character traits as a business partner that he shows as a presidential candidate.

“His written response to my letter of May 10 is characteristic of the bluster, threats, intemperance and unsupported and unsupportable falsehoods that have permeated the correspondence we have received from him and his key management employees almost since the beginning of our partnership,” Satre wrote in a 1985 affidavit filed with the court.

Harrah's ended its partnership with Trump in 1986, and Satre said Trump eventually ran the casino into the ground -- and "his employees, shareholders and bondholders suffered."

"I am convinced he simply does not have the temperament to be president, or more importantly, commander in chief," Satre warned. "His hair trigger temper, bluster, racial rhetoric and divisive domestic and international views will endanger our democracy and risk permanent damage to our society."
