Tensions remain high in Tucson, Ariz., this morning after last week's shooting and an incident this weekend at a televised town hall event. ABC's Christiane Amanpour was hosting a special town hall edition of her program, "This Week," when in the middle of the taping, survivor of the shooting, James Eric Fuller, attempted to photograph TucsonTea Party Organizer Trent Humphries and said, "You are dead," when Humphries began to speak.
Fuller is undergoing mental health evaluations this morning. On American Morning today, Humphries talks to AM's Kiran Chetry about what may have provoked the exchange.
