An interfaith service is planned in Tucson on Sunday to commemorate the two-year anniversary of the shooting of former Congresswoman Gabrielle Giffords and others at a political event.
Six people died Jan. 8, 2011. Giffords, along with 12 others, were hurt, including her district director, U.S. Rep. Ron Barber.
Barber spoke at two events Saturday - one in Green Valley and one in Tucson - that are part of a movement called BEYOND.
It was started by the family of Gabe Zimmerman, who was one of those killed.
Giffords was shot in the head and later resigned from Congress.
Jared Lee Loughner was sentenced in November to life in prison.
Barber also is set to speak at Sunday's interfaith service at St. Augustine Cathedral in Tucson.
A TV interview with Giffords and her husband will air on Tuesday.
ABC says Giffords and retired astronaut Mark Kelly will speak during the interview about a new initiative they're launching. The network didn't specify what the initiative would aim to do.
Giffords and Kelly met Friday with the families of victims in last month's shooting in Connecticut that left 26 people dead inside an elementary school.
The couple met earlier in the week with New York Mayor Michael Bloomberg, a longtime gun control advocate.
