You know what, I couldn't find an example of Trump directly denying American citizens constitutional rights (though I didn't look in great depth, I'm sure he's come close, and I'm sure others would/will step up and say he has). However, I couldn't find anything that said Terry McAuliffe had done anything to the white nationalists outside of telling them “Go home. You are not wanted in this great commonwealth. You pretend that you are patriots, but you are anything but patriots.” It seems to me that those are only words and not official actions on behalf of his office; he's certainly not denying them their constitutional rights based on that.
