He worked alongside people with mafia connections...
Which people?
Also, what was the name of the construction company he owned that built Trump tower?
When he built Trump Tower, he first knocked down an existing building with a culturally important Art Deco facade. He promised to preserve the facade. In practice he had it destroyed with sledgehammers. He hired Kaszycki & Sons Contractors, a window washing business to do the work. The non union Polish immigrants doing the work didn’t wear safety gear despite the dangers. There was no safety inspection of the worksite, despite that being a legal requirement. It is well documented that Trump was aware of the safety violations as he talked to others about that. Most workers were not union members. A dissident union member sued the company, Trump and Trump’s financial partner. The court judge ruled that Trump would have been fully aware of safety violations and had engaged in a conspiracy to cheat the workers of their pay. Unfortunately the final settlement was and is sealed, which is all too common when Trump is sued and loses.
Trump was a senior board member of the American Academy of Hospitality, basically a scam company to give awards to Trump, alongside Joseph Cinque aka Joey No Socks and The Preppy Don, who was involved in organised crime. Trump also worked alongside Fred Satter, an organised crime figure, who confessed in court to a $40 million organised crime swindle. He’s worked with other people with a history in organised crime,
The above are just a few incidents from Trump’s life, it takes me time to search through books, so I’ll leave it at that. But you can also read biographies of Trump for yourself.
Woody Guthrie even wrote a song about Fred Trump, Donald’s father, and how he cheated people. Donald’s grandfather made a small fortune running brothels during a gold rush. It’s all well documented. Hardly surprising then that D. Trump created Trump University, which was essentially a scam investment advisory company, ripping people off by selling worthless courses. He was sued for fraud. He made countless false statements about the so called university and its staff. It was investigated by consumer protection agencies who declared the courses to be worthless. There were several investigations for fraud, oddly enough senior political figures received substantial campaign donations from Trump, and their investigations withered on the vine. a common occurence with Trump businesses.
