The use of "high treason" against political enemies had faded by 1788, but the memory of its use for this purpose was still vivid for the Founders. It is for this reason that "treason" is the only crime that is defined in the US Constitution, and its why there is only one grade of treason in our law.
Oh that’s right, yes I must have heard that a million times in movies and read it in books “High treason against the King” but never in the US. Ha that’s funny, I don’t know why I thought it existed in the US as well. Well either way, if Hillary was actually involved in selling or just giving secrets to foreigners she is mince meat, or SHOULD be. I’m reminded of that guy former FBI agent Robert Hanssen who sold secrets to the Russians and is now doing life in Colorado Supermax. 23 hours a day in a cell the size of a broom closet, one hour out a day to walk 10 paces in a hole. If they don’t indict her and it’s leaked out that she WAS involved in something like that, what do you think will happen? I guess the people really couldn’t do anything, but man oh man, it would just be such an extreme betrayal. “Only little people go to jail, Hillary gets to play President”
