What false statements did Don Jr. make?
By any reasonable standard he probably didn’t make any false statements, however, the FBI has used sketchy “false statement” tactics to nail whoever they want. Similar to the old “tax evasion” charge often used to nail difficult targets.
But I do know that Mueller and the judge and/or jury are the ones to decide if a false statement was made. It's not up to Don Jr. or you or I.
It does say the Stone predicts an indictment of Don Jr. in a process crime, which is basically getting caught in a trap by the prosecutors so they can nail you for "lying to the FBI".
I was merely pointing out that indicting Don Jr. would more than likely cross Trump's "red line" for the Mueller witch hunt having gone one step too far.
It would precipitate some action by Trump. Putting his foot down to stop this could get ugly.
