After Rep. Martin Sweeney of Ohio delivered a scathing attack on the Roosevelt administration for allegedly using conscription as a way to get the United States into the war, Rep. Beverly Vincent of Kentucky, who was next to Sweeney, loudly muttered that he refused “to sit by a traitor.” Sweeney swung at Vincent, who responded with a sharp right to the jaw that sent Sweeney staggering. It was, said the House doorkeeper, the best punch thrown by a member of Congress in fifty years.
