People Protest Outside the White House after a Mass Shooting in El Paso, Texas

Hundreds of people seeking tougher gun control laws marched on the White House and the Capitol on Saturday night in a demonstration inspired by the shooting in El Paso, Texas.

Some of the participants from the activist group, Moms Demand Action, chanted “El Paso” as they marched with banners.

The groups, wearing their traditional red t-shirts, are pushing for a Senate bill on background checks for people wanting to buy guns.

Police officials in El Paso, Texas, say they are investigating as a possible hate crime the mass shooting Saturday at a Walmart that ended with at least 20 people killed and 26 wounded.

Police chief Greg Allen said the police have an online posting reportedly written by the 21-year-old white male suspect now in custody, that indicates the shooting spree was intended to target Hispanics. See Less
