Trump biographers agree Democrats ‘will discover amazing things’ in Trump’s sketchy business practices

Biographers who have written about President Donald Trump joined CNN's Don Lemon on Monday to outline his unethical business practices that date back decades.

"Is the president in for a rude awakening when Democrats take over the House?" asked Lemon.

"Well, he is," Michael D'Antonion explained. "And if they go back far enough, they're going to discover amazing things. I mean, the number of Russian mobsters who were investing in Trump properties is stunning."

He recalled that one man who lived in the unit right below Kellyanne Conway was shot and killed.

"There was a fellow who went into one of Trump's buildings, actually bought the unit right below Kellyanne Conway's unit," he explained. "He invested in it, sold it a month later for a half-million-dollar profit, [and] a year after that he gets shot to death on the sidewalk in New York City. There is such a mess in this Trump Organization. There are so many frauds to be investigated, so many crimes to be investigated."

He went on to discuss the 2015 Trump Taj Mahal casino scandals, where the company was forced to pay a $10 million fine for money laundering.

"They had to confess to this practice going on for years," he continued. "So, I think Congressman [Adam] Schiff (D-CA) is absolutely right. There's a red line they should march across and deploy the troops in all directions."

David Cay Johnston agreed, recalling an illegal gambling operation that was going on right underneath Donald's triplex with "Russian gangsters." The FBI ultimately shut it down.

"And Donald was 'What? What? There's gambling going on in my building!?" Johnston joked, quoting the notorious line from Casablanca. "And the other was when Donald's close business associate, for whom he did favors, the international cocaine smuggler Joe Wexelbaum, got out of jail he didn't have money to pay his federal fine. I think it was $30,000. But somehow ended up living in a multimillion-dollar Trump Tower [apartment] there are just so many of these stories. The ones Michael mentioned and the one I did, and there are others, that will lead to all sorts of corruption around Trump involving money and money laundering."
