WASHINGTON (AP) - A gun-control organization led by former Rep. Gabrielle Giffords and her husband, former astronaut Mark Kelly, is focusing on at least 11 congressional races this year.
    
Americans for Responsible Solutions says it will back a slate of mostly Democratic incumbents who have supported efforts to expand gun sale background checks that stalled in the Senate. The group has raised about $14.5 million since it was founded in January 2013.
    
Some of the Senate Democrats receiving help include Mark Udall of Colorado, Mary Landrieu of Louisiana and Kay Hagan of North Carolina. The group also plans to help two Republicans: Maine Sen. Susan Collins and Pennsylvania Rep. Mike Fitzpatrick.
    
Giffords was severely wounded in a January 2011 shooting in Arizona that killed six people.
