WOODBURY - Today marks two years since a gunman opened fire at a supermarket in Arizona where former Congresswoman Gabrielle Giffords was meeting with constituents.

Giffords and her husband Mark Kelly have launched a new initiative to stop gun violence.

The initiative is aimed at curbing gun violence and comes in the wake of the mass killing at Sandy Hook Elementary School in Newtown, Conn. 

Early this morning, Giffords and her husband launched the website called "Americans for Responsible Solutions.” 

The website calls on elected officials to work toward stopping gun violence and raising funds to balance the influence of the gun lobby.

Giffords says she has one word about gun violence in America, "enough."
