Gabrielle Giffords' two year anniversary of Tuscon shooting that left her injured

Gabrielle Giffords is talking about her personal struggles to ABC News on the second anniversary of the mass shooting that left her gravely wounded. This comes as the former congresswoman and her husband talk about their plan to talk about gun law reform across the nation.

Lawmakers on Capitol Hill who refuse to support gun law reform will have to look at Giffords in the eye and tell her why not. A victim of gun violence, she is now a vocal gun control advocate. Giffords is making remarkable progress, even though she still has some trouble getting the right words out.

“So slowly, so slowly,” she says.

Two years ago at a constituent rally in Tucson a gunman opened fire, killing six and injuring 13. One of his bullets pierced the Arizona congresswoman’s brain. It’s still difficult for her to get around, but she is vowing to walk the halls of Congress promoting her new cause.

In an exclusive interview with ABC’s Diane Sawyer, Giffords and her husband, former astronaut Mark Kelly, say they’ve formed a new group, “Americans for Responsible Solutions,” and they’re taking aim at powerful gun lobby groups.

“The gun lobby even opposes a gun purchaser being checked against the terrorist watch list. Doesn’t that seem like a common sense thing to do?” asks Kelly.

They say it was the Newtown massacre that moved them to act and what they’re pushing for is common sense change led by gun owners.

“Gabby and I are both gun owners,” says Kelly. “We are strong supporters of the Second Amendment. I bought a gun at WalMart recently and I went through the background check. Why can’t we just make it more difficult for criminals and the mentally ill to get guns?”

The White House welcomes Giffords’ help on the issue. Vice President Biden has a taskforce looking at gun control reform and in a sign of the times has invited the NRA to the White House this week to be a part of those talks.
