Former congresswoman Gabrielle Giffords (D-Ariz.) and her husband, Mark Kelly, will headline a fall fundraiser for a leading Senate candidate, Rep. Bruce Braley (D-Iowa), the congressman announced Friday.

Giffords and Kelly will attend Braley's ninth annual "Bruce, Blues, and BBQ" fundraiser on Oct. 27. The event will be held in Des Moines for the first time.

Braley is running for retiring Democratic Sen. Tom Harkin's seat and is widely expected to cruise to his party's nomination.

Along with Kelly, Giffords, who nearly lost her life in a 2011 assassination attempt, have been among the most outspoken gun-control advocates in the country.
