The reason for the long delay before answering is because the video feed is delayed due to the distance he is from the broadcast center. Dr. Paul was actually answering as soon as Wolf finished talking to him. It did seem like it was much more delayed than it should have been though.
Glad to see him talking about the inhumane, crime-feeding federal war on drugs. He is a doctor, he took an oath to preserve life. He knows that ending this bloody war on drugs will save so many Americans from death and bereavement that he is willing to take on the ruthless establishment to do so.
Dr. Paul is a true American patriot who would lay down his life for our freedom.
