Vice President Joe Biden speaks at a campaign rally at Renaissance High School in Detroit, MI. Biden criticizes Republican presumptive nominees Mitt Romney and Representative Paul Ryan (R-WI) for their economic and tax proposals. He says the Republican Party had lost touch with ordinary Americans, noting "Folks, this is not your father's Republican Party. This is not Mitt Romney's father's Republican Party." He praises Detroit and Michigan for their resilience and perseverance. Biden is introduced by Flint native and Olympian Claressa Shields, winner of the gold medal in women's boxing.
