Newark Mayor Corey Booker offered an unflattering opinion on Republican vice presidential candidate Paul Ryan last night on Piers Morgan Live.

"The Ryan congress under his leadership, his votes drove up the federal deficit in a dramatic way," Booker said. "And then if you now see what Romney is doing, which is adopting basically much of what Ryan stands for, you see a tremendous amount of draconian cuts that are undermining the urgencies in America right now."
