LOL .. Roberts says that he was just about to finish answering the question, but you Senator didn't want to hear it
Arlen slaps Biden again to let Roberts answer the question
Biden whines about his time is running out .. but yet Biden keeps on talking
I will give Arlen credit for understanding the difference between disagreeing and being disagreeable. It's one of my chief complaints with these Dems...they are unable to make their points without bullying, interrupting and disrespecting the nominee.
