They settled out of court both times. You do that if there wasn't actual evidence?
He "denounced" it after he got blasted over it on every major outlet after he wouldn't do it on air. I'm sure you believe the "faulty ear piece" excuse of why he wouldn't denounce them on CNN.
There were also first hand accounts of Trump's racism at that casino specifically involving him and his requests which is why they were fined. I'm sure no evidence gets you a $200,000 fine too.
You do realize that 95% of the time companies settle lawsuits because it is significantly cheaper than going through litigation, involves less time, and you don't admit any fault? You do know that right?
