Katy Perry, Lady Gaga and More Sign Billboard Letter to Congress Urging Gun Control

Those who signed support background checks.

In the wake of the massacre at Pulse nightclub in Orlando and the fatal shooting of singer Christina Grimmie, those who signed the letter are urging Congress to require a background check for every gun sale and block suspected terrorists from buying guns.

“As leading artists and executives in the music industry, we are adding our voices to the chorus of Americans demanding change,” the letter reads. “We call on Congress to do more to prevent the gun violence that kills more than 90 Americans every day and injures hundreds more.”
