Former U.S. Rep. Gabrielle Giffords (D-AZ) and her husband, Mark Kelly, launched a political action committee aimed at curbing gun violence today, the second anniversary of the Tucson shooting that killed six people and left her critically injured, reports the Associated Press. Giffords and Kelly wrote in USA Today that their Americans for Responsible Solutions initiative would help raise money to support greater gun control efforts.

"Achieving reforms to reduce gun violence and prevent mass shootings will mean matching gun lobbyists in their reach and resources," they said, aiming to "raise funds necessary to balance the influence of the gun lobby." The couple last week visited Newtown, Ct., where a gunman opened fire in an elementary school, killing 20 children and six adults. They also met with New York City Mayor Michael Bloomberg. In ABC News interviews, Kelly described a meeting with a father of a Connecticut victim in which he "just about lost it" after the parent showed him a picture of his child. When asked by ABC's Diane Sawyer about when such violence happens to school children, Giffords responded: "Enough."
