Is that something you could elaborate on? Just curious as most is second hand accounts or people with a different agenda.
When Trump formed his presidential exploratory committee in 1999 to then test the waters for a presidential run as a Reform Party candidate, I was hired to work on it. When Trump concluded that such a run would not be successful (the national Reform Party collapsed into a hopelessly dysfunctional mess) exploratory activities ended. That seemed to me to be a wise decision. That's exactly what exploratory committees are designed to do; test the waters and make decisions based on what is learned.
Despite proper billing and repeated submissions to the same address all previous invoices had been submitted and paid, my final invoice and all collections attempts were ignored. This was a long time ago. I do not remember the amount in question but do remember making the decision to suffer the loss instead of making a public stink, going to court or turning the invoice over to a collections agency.
So, years later, when I read reports in the news about how Trump stiffed certain people in his business operations, I am predisposed to believe them.
