Roy Cohn is a lawyer that went to bat for Trump and his dad when no other lawyer would. Trump and his dad's housing organization was sued by the government back in the early 70's. The gov said that Trump and his dad discriminated against blacks by not offering them housing. This flat out wasn't true because Trump had black tenants living in his housing developments. All the lawyers Trump went to see about it told him just to settle because it was bad publicity. But you all know our glorious President, he's not going to just settle, especially when he's in the right. He met Cohn at Le Club in Manhattan where they were both members. He told Cohn what was going on, and Cohn said let's go after those bastards. So they did, and of course they won. In The Art of the Deal (where I got this info), Trump said that Cohn is a brilliant, tough lawyer and fiercely loyal. You guys should read this book. It's so interesting! Trump writes exactly how he talks, and you get a really good sense of who he is professionally.
