The article explains at the beginning: "An eight-month investigation ... reveals that the post-millennium Trump business model is different from what has been previously reported. The Trumps were typically way more than mere licensors or bystanders in their often-troubled deals. They were deeply involved in these projects. They helped mislead investors and buyers — and they profited handsomely from it."
"Patterns of deceptive practices occurred in a dozen deals across the globe, as the business expanded into international projects, and the Trumps often participated. One common pattern, visible in more than half of those transactions, was a tendency to misstate key sales numbers."
Hopefully federal prosecutors are already investigating these incidents for possible crimes.
I recommend reading the linked article. It's on the long side but nonetheless provides a clear picture of the President's dishonesty and potential criminality.
