1) yes he can because one doesn’t justify the other, unless you’re going to suggest the left are the same as Trump..
2) he didn’t “ask” Russia for help, it was said in a sarcastic manner. Do you really think Trump is going to ask a foreign adversary, on national television, to hack the opposing candidate? Be serious.
No Russian collusion was ever found, Russia would have tried to interfere anyway, it’s what other countries do. Hell, the U.S. has interfered in elections too, I mean shit, we’ve helped to overthrow governments.
