Hundreds of thousands of people filed out into the streets in cities across the U.S. on Saturday to call on the Trump administration to reunite families separated under the presidents zero-tolerance border policy. The Families Belong Together event, which includes more than 600 planned marches, were due to kick off around midday in both major and smaller U.S. cities, as well as London and Berlin. The rallies were backed by the American Civil Liberties Union and several immigrant advocacy groups, but many of those in attendance were new to activism and said theyd simply felt compelled to speak out against what many see as inhumane policies. President Trump backtracked on his family separation policy last week, but organizers say the fate of hundreds of migrant children is still in the balance. We have to keep moving, the Trump Administration cant be trusted to follow through. We dont see this as a legislative problem, this is a Trump Administration problem, Jess Morales Rocketto, the policy director of the National Domestic Workers Alliance, told TIME magazine. Trump has so far remained silent on the demonstrations, instead tweeting out a message of support to Immigration and Customs Enforcement agents, whom he praised for doing a fantastic job of eradicating the worst criminal elements.
