By KC Baker Published on October 2, 2017 11:27 AM Share Tweet Pin Email Photo: Todd Williamson/Getty For a summer 2017 issue of PEOPLE, Academy Award-winning actress Julianne Moore spoke to staff writer KC Baker about participating in the Wear Orange campaign, which takes place annually on June 2, National Gun Violence Awareness Day. Moore, 56, also opened up about what inspired her to take action to promote gun safety. On Monday, Moore tweeted “#endgunviolence” in the wake of the Las Vegas mass shooting that occurred late Sunday night — now the deadliest mass shooting in U.S. history. “I mourn this senseless loss of life,” she wrote. “What will it take, #Congress, for you to act?” When the Sandy Hook shooting happened on Dec. 14, 2012, my daughter was 10 and was coming to work with me on a movie set. I asked hair, makeup, crew and other actors, “Please don’t mention this to her.” I was going to wait to tell her with her dad. But somebody posted something about it on her monitored Instagram account. She said, “Mommy, did a bunch of little kids get shot today?” It occurred to me that I wasn’t protecting my daughter by trying to keep the news away from her, so I wanted to get involved. Chris Hardy I reached out to the nonprofit organization Everytown for Gun Safety and started the Everytown Creative Council in 2015 — gathering other members of the creative community including Jennifer Lawrence, Amy Schumer, Alec Baldwin and Jennifer Aniston, who support gun-violence prevention. That’s why the Wear Orange campaign is so important. It calls for people to wear orange on June 2 to send a message to end gun violence. The Wear Orange campaign shows that you can make a difference. This is not an anti-gun or pro-gun argument. It’s a safety issue. In our country we have a right to bear arms. But we also have a responsibility to bear arms safely. On an average day, seven kids or teens are killed by guns. With regulation, you reduce deaths.

We’re talking about closing the background loophole, when guns are allowed to be sold without background checks, so there are fewer illegal guns in the world. If we can manage to do that, that’s a pretty awesome thing and something we need to ask our legislators to do as well. How to Help and Learn About Loved Ones Friends and family are asked to report missing people believed to be connected to the shooting using the hotline 1-800-536-9488. Anyone with photo or video evidence of the shooting is asked to call 1-800-CALL-FBI. The city of Las Vegas has established a Family Reunification Center to help connect relatives with the more than 500 people who were injured. In addition, city officials urged those locally who wish to donate blood to visit one of two donation centers operated by United Blood Services, either at 6930 W. Charleston in Las Vegas or at 601 Whitney Ranch Drive in Henderson, Nevada. A victims’ fund has been started on GoFundMe by Steve Sisolak the Clark County, Nevada, commission chair. Other groups providing relief include the local chapter of the American Red Cross and the National Compassion Fund.
