Sen. Bernie Sanders made a surprise appearance at the Coachella Valley Music and Arts Festival Saturday night.

As part of an introduction to the performer Clairo, Sanders told Coachella attendees that the fate of America lay with the younger generation. He urged younger people to become politically active to fight for progressive causes like universal healthcare, women’s rights and to prevent climate change.

“This country faces some very difficult challenges,” he said. “And the future, what happens to America, is dependent on your generation.”

With him, Sanders brought U.S. Rep. Maxwell Frost, a congressman from Florida’s 10th Congressional District, which includes Orlando.
