Democrat Ron Barber said Monday he will run for the Congressional District 2 seat in Southern Arizona this fall.

Barber made the announcement in a telephone conference call with reporters.

Barber is now a candidate for the June 12 special election in Congressional District 8 to finish the term of his former boss, Gabrielle Giffords, who resigned in January, saying she wants to devote full time to her recovery from the bullet wound she suffered to the head in the Jan. 8, 2011 shooting in Tucson.

Barber was seriously wounded in that shooting, too. Six people were killed and 11 others besides Giffords and Barber were wounded outside a Safeway store as Giffords began meeting constituents at what she called a "Congress on Your Corner" event.

Redistricting will change the configuration of Arizona's congressional districts. CD8 will become CD2, smaller in size geographically but covering largely the same territory, Cochise County, eastern Pima County and Tucson and part of Santa Cruz County.

Barber faces no opposition in the CD8 special election primary. Four other Democrats had announced for the CD2 primary, but on Monday, one of the four, state Rep. Steve Farley of Tucson, said he would instead run for a seat in the state Senate.
