Melissa McCarthy, Emma Stone, More Stars Urge People to #RejectTheNRA

Julianne Moore, Bill Hader, Laura Dern, Sheryl Crow and Adam Scott also participate in the clip encouraging Americans to reach out to their Congressional representatives in the wake of the Las Vegas shooting.

In response to the devastating mass shooting in Las Vegas on Oct. 1, stars including Melissa McCarthy, Emma Stone, Bill Hader, Laura Dern, Sheryl Crow and Adam Scott have teamed up for a video showing how everyday Americans can call on their congressional lawmakers to reject legislation that would roll back gun silencer safety laws and to reject a national concealed carry reciprocity bill.

Emma Stone starts off the clip. "The mass shooting in Las Vegas has left all of us grieving, scared and angry," she says. "Knowing what to do about it can be confusing. Here's one thing that can make a difference right now," Bill Hader adds. A slew of stars then urge viewers to text "REJECT" to 644-33 to connect them to Everytown Gun Safety, which will then connect people with their Congressional representatives. The group also provides a script to use when speaking to lawmakers.

The video is part of a large grassroots effort to #RejectTheNRA. Everytown for Gun Safety Action Fund and Moms Demand Action for Gun Sense in America, part of Everytown, announced Tuesday that they will send 1 million phone calls to reject the NRA and its policies. Through November 2018, Moms Demand Action volunteers and supporters of Everytown will work to get the word out to demand that legislators stop efforts to roll back gun silencer safety laws and to pass so-called concealed carry reciprocity. They will also back candidates who support gun safety.

"The NRA has spent millions electing the President and Congress it wants — but grassroots momentum is on the side of gun safety,” said John Feinblatt, president of Everytown for Gun Safety, in a statement. “By sending 1 million calls, we’ll prove the power — and passion — of Americans hungry for change. The NRA’s leadership is deeply out of touch with the American people, and we’ll make sure Congress and lawmakers in states hear their constituents loud and clear.”
