Yes, they should be banned and charged with a crime. Anyone person knowingly involved with foreign agents who plan to ‘help’ a candidate get elected should also be charged with a crime and severely punished. This gets to the very heart of our democratic republic’s ability to be, well, Democratic. I am very concerned about the wanton in-your-face disregard of senior politicians, political appointees, and even congressional staffers to honor their oath’s to protect our country and to honor one of the more sacred founding principles of this country’s Constitution. We constantly see this being disregarded the administration, the trump’s supporters, and the trump’s enablers - as they all feel they are too entitled to be bound by such a ‘quaint’ principal of honoring their primary duties of office, to honor and protect our country and our Constitution.
