A number of celebrities joined the March for Our Lives rally for gun reform across the U.S., in an attempt to use their platforms to spread the word of the #NeverAgain movement.

The March for Our Lives’s main event took place in Washington D.C., near the Capitol, where celebrities like George and Amal Clooney, Jimmy Fallon, Halsey, Cher, Glenn Close, Kim Kardashian, and Kanye West came out to march. Others were set to perform, including Demi Lovato, Vic Mensa, Lin-Manuel Miranda, Ariana Grande, Jennifer Hudson, Common, Andra Day, Ben Platt, and Miley Cyrus. 

The Los Angeles rally was also swarming with celebrities, including Amy Schumer—who’s previously been vocal about gun control, when a shooting occurred at a Louisiana screening of her movie Trainwreck. Olivia Wilde, Cappie Pondexter, Yara Shahidi, Meg Donnelly, Ta’Rhonda Jones, ​Trevor Hall, Jacob Sartorius, Skai Jackson, and others also showed thier support.

In New York, Paul McCartney marched and paid tribute to John Lennon, who was shot and killed in 1980.
