Dozens of protesters on Thursday staged a sit-in at the U.S. Senate Hart Building in Washington to protest the Trump administration’s immigration policy.

Police have arrested about 40 people — mostly women — inside the atrium of the federal building as part of the #WomenDisobey protest, according to CNN.

“They want to create a big moment up here on Capitol Hill the day that many lawmakers will wrap up their legislative work and head home without addressing the family separation issue,” CNN correspondent Sunlen Serfaty reported.
