George and Amal Clooney, Miley Cyrus, Paul McCartney and more stars at March for Our Lives rallies

The stars were out in full force at March for Our Lives rallies on Mar. 24 following an outpouring of financial support for the cause of students from Stoneman Douglas High School, the site of a horrific school shooting on Feb. 14. Standing up against gun violence in the hopes of #neveragain seeing innocent people murdered by the weapons, celebrities like George and Amal Clooney, Miley Cyrus, Paul McCartney, Kim Kardashian and Kanye West rallied around hordes of young people to try to make a difference.
George and Amal donated a whopping $500,000 to the cause following the shooting in the names of their nine-month-old twins, Ella and Alexander. And as promised, the parents were on their feet in Washington, D.C. alongside John Mayer, Katie Couric and Jimmy Fallon. The actor also penned a letter published in The Guardian a day before the march, saying, "Amal and I are 100% behind you."

Matthew McConaughey gave a moving speech during the Austin, Texas rally. He said: “This is an American issue. It’s a Texan issue. It’s a legal and law-abiding gun owner issue. It’s a mother issue. It’s a father issue. And, quite literally, this is our children’s issue. My hope here is that we can find a common ground on what I see as a very much a common sense issue. This is an issue anchored in purpose for all of us. It’s not anchored in politics. God bless and just keep living.”

Thank you Emma Gonzalez!"

Lin-Manuel Miranda stood with Parkland student, and one of the faces of the march, Emma Gonzalez. During her time on stage, the 18-year-old stayed silent for much of the six minutes and twenty seconds. This was the amount of time it took for 17 lives to be taken on Feb. 14 at her school in Florida. With tears streaming down her face, it was a powerful moment of silence.
She said: "Six minutes and about 20 seconds. In a little over six minutes, 17 of our friends were taken from us, 15 were injured, and everyone, absolutely everyone, was forever altered. Everyone who was there understands, everyone who has been touched by the cold grip of gun violence understands."
