If stuttering is a credibility issue for you than why is kavanaugh a gop endorsed supreme court justice? He was brutal on that tip. Taylor has stuttered and made long pauses his whole career. That and he's old. It makes him no less credible and the information he provided is widely accepted as factual by everyone on both sides. If he was thought as non-credible, the GOP would have been attacking his credibility and not the bidens. Everyone believes this man's word. It's just a matter of how you feel about it. But if you're implying he's not being truthful, you're in a pool with basically no one else in politics.
