While it was mildly funny in a bababooey sort of way, it was pretty stupid and trashy to do on a kids Christmas show. He should be accountable for his actions, if only that he should be ashamed of himself for dragging politics into an event for kids.
But holy sweet Jeebus, how does the president have absolutely zero self awareness there? And please don't try to claim that Biden had any idea WTF he was talking about, either. Biden has such a short fuse that he would have probably challenged the guy to a pugulistic battle at the 5 and dime at high noon if he knew what "let's go Brandon " meant. Which further begs the question, how is it possible that Biden STILL doesn't know what that means? Is je not allowed to watch the news? Was he told and forgot?
