Paul McCartney, Lady Gaga, Katy Perry, Barbra Streisand and Billy Joel are among a long list of celebrities who have signed an open letter from Billboard magazine to Congress about stopping gun violence in America.
Billboard posted the letter along with over 200 signatures from musicians and executives, including Cher, Jennifer Lopez, Elvis Costello, Britney Spears, Lin-Manuel Miranda and Sting, on its website Thursday.
"We call on Congress to do more to prevent the gun violence that kills more than 90 Americans every day and injures hundreds more," Billboard wrote.
The magazine said its editors were horrified by the recent shooting in Orlando, Florida, and Christina Grimmie's death, and felt connected to both incidents because the "tragedies occurred where musicians and music fans gathered."
Billboard "and the undersigned" — which also included Alicia Keys, James Corden, Questlove, Selena Gomez, Stevie Nicks and Bob Weir — implored that Congress "close the deadly loopholes that put the lives of so many music fans, and all of us, at risk."
Billboard's letter comes amid a growing number of celebrities voicing support for House Democrats who stage a 25-hour sit-in over gun-control legislation.
Comedian Amy Schumer, who launched a "crusade on guns" last year with New York Sen. Charles Schumer, implored her 4.13 million followers to "demand action" for gun control by texting a hotline, while actress Debra Messing similarly suggested, "I just called my Rep to support sit in for gun control vote. Please call yours and let them know you support them!"
Kim Kardashian noted, "After Orlando, Congress hasn't done anything and now they’re going on vacation. I say #NoBillNoBreak."
