The reason Biden was thrown off by Trump talking is because Trump’s words were interfering with the info his team was pumping into the earpiece in Biden’s right ear. The crosstalk was throwing Biden off. He can’t admit what really happened. It would have been funny if the had said, “Shut up! I can’t hear what they are telling me!”
Happened many times before...they must have decided to try it again. Wait for obama to say “I can’t hear myself”.
