In California, an estimated 36,000 people gathered in downtown Los Angeles on Saturday for a “Fighting Oligarchy” tour organized by Vermont independent Senator Bernie Sanders.

Sen. Bernie Sanders: “We’re fighting a president who undermines our Constitution every day and threatens our freedom of speech and assembly and whose agents are rounding up innocent people off the streets, putting them in unmarked vans and throwing them in detention centers. That is what happens in dictatorships, not democracies. And we’re going to stop that outrageous action on the part of the president.”

Senator Sanders was joined by New York Democratic Congressmember Alexandria Ocasio-Cortez. On Saturday evening, Sanders made a surprise appearance on stage at the Coachella Valley Music and Arts Festival, where he drew standing ovations as he called on people to fight for reproductive rights, workers’ rights, access to healthcare and to oppose Trump’s authoritarianism.
