 Look, I'd be happy if both the president and Donald Trump took... No, no, Joe, no. How about just Joe Biden? Because he hasn't taken one. Cognitive test. So that's a yes? You think he should take a cognitive test? I think they both should be willing to take a test. I think, frankly, a test would show Donald Trump has serious illness of one kind or another. What is that? What is that, Russia collusion guy? What exactly illness does he have? Because you are a pathological liar.
