There's not the slightest shred of evidence, Andrew McCarthy wrote in the National Review, that in making those payments Trump had any awareness of the underlying laws he's accused of trying to break.
Speaking only to this one narrow point- ignorance of the law is no more an excuse for crimes in the U.S. than it is in Canada. The offences Trump is alleged to have committed explicitly even actively involved legal counsel in their commission; he of all people can hardly claim lack of access to legal advice. He has even chosen not to mount an ‘advice of counsel’ defense despite having a personal lawyer directly involved.
So yeah, a claim that he didn’t know the law means nothing, and calls the rest of that piece into a bit of question.
