Family members, friends and others are at the University of Arizona in Tucson tonight for a "Together We Thrive: Tucson And America" service to honor and remember the victims of Saturday's shooting rampage.
President Obama will be among the speakers. First lady Michelle Obama is also in Tucson, and they have visited some of the victims and family members of those who did not survive. Six people were killed and another 13 were shot and injured when a lone gunman attacked a community event being held by Rep. Gabrielle Giffords (D-AZ).
