One problem is that, if President Trump is innocent, he doesnt need leverage. He just needs the truth.
Read the book “THree felonies a day”. That is the average number of felonies an average white collar person in America is likely to commit in a day, whether they want to or not.
I was just explaining this to people today who said if Trump nothing to hide then don’t worry. I remember reading somewhere years ago the avg American commits 3 crimes a day without knowing it. And the FBI could indict a ham sandwich I’d they wanted to. Innocence is not enough anymore.
