Gun Control Advocates Frustrated By Lack of Support in Congress

Despite mass shootings in the last year gun control legislation has not been passed by lawmakers

Joined by nearly 90 gun-control advocates, the Newtown Action Alliance, an organization formed after the deadly shooting at Sandy Hook Elementary School, went door to door to congressional offices Tuesday, meeting with lawmakers and their staff to discuss the need for universal background checks.

Sandy and Lonnie Phillips, who lost their daughter Jessica Ghawi, 24, in the massacre at the Aurora, Colo., movie theater, returned to Capitol Hill today for the first time since the background check bill failed last April.

"It's frustrating. When you're having a mass shooting every four months in America and our leaders are doing little to nothing, that's frustrating," Sandy Phillips told ABC News. "We're talking lives. We're talking about lives being taken."
