Student: This march is going to change history
(CNN) —  

On stage and in song, on social media and in silent participation, several celebrities showed their support for the student organizers behind Saturday’s March for Our Lives.

In Washington, Miley Cyrus, Ariana Grande, Common, Lin-Manuel Miranda and Ben Platt were among the performers who took to the stage to pay tribute to the 17 lives lost in the deadly school shooting in Parkland, Florida, last month, as well as people impacted by gun violence elsewhere.

But plenty of star power was present.

George Clooney

George and Amal Clooney, who donated $500,000 to the event, marched alongside the demonstrators calling for stricter gun control. The Clooneys were soon followed by other celebrity donors such as Oprah Winfrey and Steven Spielberg.

Vic Mensa

The rapper performed his song “We Could Be Free” at the March for Our Lives in Washington.

Afterwards, he spoke to CNN’s Dianne Gallagher and told her about how he became politically active after reading Malcolm X’s biography. The Parkland shooting, he said, got a lot of attention because most of the victims were white.

“It’s a very American thing, that it takes white victims for people to really listen about gun violence,” the 24-year-old said. “But that’s what is interesting about gun violence. It doesn’t discriminate. White, black, brown, yellow, everybody bleeds red.”

Miley Cyrus

Miley Cyrus performed at the march in Washington on Saturday.

Singer Andra Day performed two songs at the beginning of the march, one with fellow musician and rapper Common.

In an interview with CNN’s Renee Marsh, Day said she believed the march would make a difference.

“I think what we’re saying here today is that we’ll continue to march and we’ll continue to protest and we’ll continue to raise our voices,” Day said. “We’re not going to go away until we actually see real change. And I also think this is bringing real awareness that we change things through legislation. Each of these votes matters.”

Ariana Grande

Singer Ariana Grande was also in Washington with student activists and gun control advocates.
