“Her dedication to her country, and to her community, will make her a rising star in Congress. That means the people of the 6th District will have an effective champion in Congress. We are proud to endorse her,” VoteVets Chairman Jon Soltz said in a statement.
Houlahan served as an officer in the Air Force.
VoteVets was founded in 2006 by Soltz to help elect veterans. According to OpenSecrets.org, VoteVets gave donated $167,500 nationally last year to Democratic candidates, including $5,000 to Mike Parrish who challenged Costello and $2,500 to Joe Sestak in for his bid for Senate.
Houlahan is one of three Democrats looking to challenge Costello next year.
