Delegates loyal to Bernie Sanders — but not so loyal they’ve heeded his request to support Hillary Clinton — are wearing neon green, glow-in-the-dark T-shirts inside the Democratic National Convention. They read “Enough is enough.”

Per Yoni Applebaum at the Atlantic, those t-shirts are the work of Colorado delegate Nita Lynch:

“We felt that we should do something in solidarity with each other and with Bernie,” explained Clio Dioletis, a delegate from Denver, Colorado. The shirts are the handiwork of Nita Lynch, another Denver delegate. She went online, looking for a quote that would sum up what Sanders stood for. “He said it in every speech,” she explained. Neither is ready to support Hillary Clinton. “Not at this point,” Lynch said. “There hasn’t been enough time.”
