The third annual DC LaborFest launchestonight with a screening of Trumbo at the AFI Silver Theater at 7 pm. Bryan Cranston gives an Oscar-nominated performance as the legendary author and screenwriter Dalton Trumbo. Red-baited and blacklisted, Trumbo fought back against a witch-hunt that has lessons for anyone battling intolerance and oppression today. Then on Sunday, don’t miss the Mother Jones Memorial Wreath-Laying at noon on Powder Mill Road in Silver Spring. The legendary labor organizer claimed May Day as her birthday and after a lifetime fighting for unions and the rights of workers, the spot where she died in what is now Adelphi, Maryland is now the site of the annual commemoration. Also on Sunday, there will be a Mayday March and Rally starting at 2PM at Malcolm X Park, followed by a march to the White House as local activists join millions of workers across the globe as they express international solidarity. There are a number of other LaborFest events this weekend; check out the whole line-up here.
