Dozens of activist organizations, including the American Civil Liberties Union, MoveOn and the Leadership Conference on Civil Rights, organized the protests, which included more than 600 events on what was a sweltering hot Saturday in much of the country.
At the main event in Washington, D.C., organizers said around 30,000 showed up to hear celebrity and activist speakers including Lin-Manuel Miranda before marching to the White House. In Boston, thousands of demonstrators heard from Massachusetts Sens. Elizabeth Warren (D) and Ed Markey (D), while, on the opposite coast, Chrissy Teigen introduced husband John Legend while holding her infant son before a crowd in downtown Los Angeles.
