Much of the March for Our Lives event is being funded by donations. Celebrities like George and Amal Clooney, Steven Spielberg, Kate Capshaw, Jeffrey Katzenberg, and Oprah Winfrey all pledged to donate $500,000 each to the rally. John Legend and Chrissy Teigen donated $25,000. More celebrities may have donated less publicly, since many were tweeting about the event and talking about it on social media. Even the dating app Bumble donated $100,000 to the cause. Those donations can really add up and help with a lot of costs associated with the massive D.C. rally. It’s not just celebrities who donated. Philanthropist and businessman Eli Broad pledged $1 million to the cause, Deadline reported.
