I think it was politically motivated. However, it doesn’t matter. An attack from behind on a defenseless person is a crime. Throw the bum in jail.
An assault on a member of Congress for political reasons carries a much stiffer penalty including serious prison time.
He’s is a Senator— it is a Federal Crime. Where is/are the Federal Prosecutors in Kentucky. Rand Paul (and/or his people) should be bringing charges to a Federal Prosecutor. The facts are not in contention— the guy attacked/assaulted a US Senator. If he was a foreign national, it would be even more so.
FReepers here familiar with US Code— chime in— this IS a federal crime- a serious one... is it NOT? This cannot be ignored, because the press doesn’t talk about it.
