Former Democratic Rep. Gabrielle Giffords of Arizona has announced a new initiative to take on gun violence. Giffords suffered major head injuries and nearly lost her life in the Tucson shooting rampage that killed six people in 2011. On Tuesday — the second anniversary of her shooting — Giffords and her husband Mark Kelly announced a new group called Americans for Responsible Solutions, which they said will “raise the funds necessary to balance the influence of the gun lobby.” Writing in USA Today, Kelly and Giffords said that in the aftermath of the Newtown massacre, “We can’t just hope that the last shooting tragedy will prevent the next. Achieving reforms to reduce gun violence and prevent mass shootings will mean matching gun lobbyists in their reach and resources.”
