U.S. Rep. Ron Barber, D-Ariz., center, meets with constituents Jim Tucker, left, and his wife Doris who are the first in line to greet him during a "Congress On Your Corner" event at a grocery store on the corner of North Craycroft and East Grant Roads in Tucson, Ariz. on Saturday, June 23, 2012. The Tuckers were also one of the first people in line when Rep. Gabrielle Giffords was shot and wounded and six people were killed outside a supermarket on Jan. 11, 2011. Sworn into office earlier in the week, this is the first such event in Congressional District 8 since the shooting. Barber, who was Giffords' district director at the time, was also wounded during the shooting. (AP Photo/Arizona Daily Star, A.E. Araiza) MANDATORY CREDIT: ARIZONA DAILY STAR, A.E. ARAIZA
