Perhaps it was the 80s or 90s, but I suspect he knew Trump to be a con artist more than 20 years ago. Because businessmen know how other business men act and treat others. His name? Michael Bloomberg. ... He has lots of money, and has donated his funds to defeat Trump. (lots of money)
..I think Bloomberg ran for president, because he already knew about Trump. He interacted with him in as mayor and before that. I think he saw Trump to be a con artist long before Bloomberg got active in politics.........
.....Business executives know the kinds of people that other business executives are. Through experience, and through making deals and watching how others act and not act.
...Bloomberg knew or knew many other businessmen who knew exactly who and what Trump is...A Con Artist of the very worst kind
....I think Bloomberg will do everything and anything to defeat Trump. He has had experience with Trump for many years and has seen some things that would be hard to believe. But at this point, nothing is hard to believe about Trump...
