Following a mass shooting at an Orlando, Florida gay nightclub early Sunday morning that left 50 people dead, volunteers for Moms Demand Action For Gun Sense in America staged a demonstration outside New York’s Beacon Theatre before Sunday’s Tony Awards.

Moms Demand Action is part of Everytown for Gun Safety, a “movement of Americans working together to end gun violence and build safer communities.” The group encourages supporters to wear orange items of clothing (or #wearorange on social media).

The Orlando massacre will be a large focus of the 2016 Tony Awards ceremony. Earlier in the day on Sunday, Tonys organizers dedicated the show to the victims of the attack. “Our hearts are heavy for the unimaginable tragedy that happened last night in Orlando,” said representatives for the Tonys in a statement. “Our thoughts are with the families and friends of those affected. The Tony Awards dedicate tonight’s ceremony to them.”

In addition to the show dedication, the Tonys also created special ribbons to honor those who lost their lives in the shooting.
