Former New York City Mayor Michael Bloomberg has launched a new gun-control group aimed at taking on the National Rifle Association. Bloomberg has committed $50 million to funding Everytown for Gun Safety, a grassroots group of voters against gun violence. Lisa Wheeler-Brown, a Florida mother who lost her child to a shooting, and Seattle Mayor Ed Murray were among those to join the group’s unveiling.

Lisa Wheeler-Brown: “Someone murdered my son with an illegal weapon, so I’m going to do all I can to prevent another mother from losing a child to gun violence.”

Mayor Ed Murray: “Today we’re announcing Everytown for Gun Safety, a new organization that brings mayors, moms and the grassroots movement of Americans together to deal with the issue of gun violence. Gun violence kills 86 Americans every day. It happens everywhere—in big cities, small towns, on our streets, schools, shopping malls and places of worship.”
