 Giffords and husband Mark Kelly announced Tuesday that they had formed a political action committee to prevent gun violence and bring changes to laws, such as requiring comprehensive background check for firearms sales. They outlined the effort in an editorial in USA Today and in an interview on ABC News that also provided a new glimpse at Giffords' recovery since she was shot in the head two years ago by a mentally ill gunman. "Physical therapy, yoga, speech therapy," she said. She has a service dog named Nelson that helps her keep balance and guides her. Full Coverage: Tragedy in Newtown 
 
 "Strength," Giffords said she told the families in Newtown. She said "daggers" to recount her tense, face-to-face encounter with shooter Jared Lee Loughner at his November sentencing. She said "sad" to describe his mental illness. She's made a remarkable recovery since then, but still has a long way to go. The couple marked the second anniversary of the Tucson shooting by sitting down with Diane Sawyer to discuss their recent visit to Newtown and their new initiative to curb gun violence, "Americans for Responsible Solutions."

 The first change the couple hopes to enact is to require a comprehensive background check for the private sale of firearms. You can walk up right in front of a cop and buy a gun, no background check, nothing," said Councilman Steve Kozachik, who led the gift card program.

 Giffords, 42, and Kelly, 48, are both gun owners and supporters of the 2nd Amendment, but Kelly had strong words for the National Rifle Association after the group suggested the only way to stop gun violence is to have a "good guy with a gun." An attorney who lives in the Sandy Hook section of Newtown, Monte Frank, is organizing a bicycle ride from Sandy Hook to Washington, perhaps in March, to call for stronger gun control laws. He said he is eager to help Giffords in any way he can. There was a good guy with a gun, Kelly said, the day Jared Loughner shot Giffords and 18 other people, six fatally, at her "Congress on Your Corner" event. "It was just very tough and it brought back a lot of memories about what that was like for us some two years ago."
– Gabby Giffords and Mark Kelly sat down with Diane Sawyer last night to talk about their new gun control group and their emotional visit to Newtown in the wake of the school shooting there. Highlights from ABC News: Giffords and Kelly, both now retired, initially imagined a life out of the spotlight, but after the Sandy Hook shooting, Giffords says, she thought: "Enough." That was what convinced them it was time to take action. Giffords' message for Newtown was "strength," she says. "Gabby often told them, 'You got to have strength. You got to fight for something,'" Kelly adds. "Yes, a Glock," Giffords says when asked if she still owns a gun. "Gabby and I are both gun owners," says Kelly. "We are strong supporters of the Second Amendment. Why can't we just make it more difficult for criminals and the mentally ill to get guns?" They also oppose extended magazines: "An extended magazine is used to kill people," he says. "Lots of people." As for the argument that more people with guns could actually stop gun violence, Kelly says there was "a good guy with a gun" nearby when Giffords got shot, and he almost shot the wrong person. "After the shooting in Tucson, there was talk about addressing some of these issues, [and] again after [the movie theater massacre in] Aurora," Kelly says. "I'm hopeful that this time is different, and I think it is. Twenty first-graders being murdered in their classrooms is a very personal thing for everybody." The couple also talks about Giffords' progress since her injury. She calls it a "struggle," but says she is still improving. "You're walking faster, and if I tug you along, you can go even faster," Kelly says. And she plans to walk through the Capitol talking about gun control. Meanwhile, yesterday in Tucson, the second anniversary of the shooting that wounded Giffords and killed six others was marked by competing events in a police station parking lot, the AP reports. A councilman on one side of the lot gave out $50 gift cards to people who turned firearms in to police; a state senator on the other side organized an unregulated marketplace where guns were legally exchanged with no paperwork required. And Roxanna Green, mother of the youngest victim Christina-Taylor Green, released an ad calling for gun control.
