The National Rifle Organization (NRA) on Thursday used armed security to force mothers of victims of gun violence to leave the organization's headquarters.

The groups and the Reston-Herndon Alliance to End Gun Violence traveled to NRA headquarters in Virginia on Thursday to deliver a petition with over 150,000 signatures calling for universal background checks, a ban on high-capacity magazines, a ban on military-style assault rifles and new laws to crack down on gun trafficking.

Included in the group were mothers like Lori Haas, whose daughter was wounded in the 2007 shootings at Virginia Tech, and Louisa Davis, whose nephew was killed by a gun in North Carolina.

But in video captured by WUSA, a plainclothes security guard and an armed uniformed guard are seen refusing to accept the large stack of signatures and then shooing the gun safety advocates off NRA property.

"They're not willing to listen to all members," one NRA member who was in the group told WUSA. "We're in a democracy, we need to have a conversation. And the NRA likes to shut down conversation."
