re: Would someone please explain the crimes Trump committed?

You need to learn how to read. Where did I say it is against the law. I didn't. In fact read a few posts above that one I clearly stated it is NOT against the law. My point was had Trump just admitted the affair from the outset there is no reason to have an NDA which left a paper trail which lead to the questions about where the money came from for the payments etc.

Nowhere in that post you quoted did I say or even infer that NDA's are against the law.
