Three Democratic congresswoman were planning to visit a shelter for migrant children in Homestead, Florida, on Monday—but the Trump administration won’t let them in. The Department of Health and Human Services told the Miami Herald that Reps. Debbie Wasserman Schultz, Donna Shalala, and Debbie Mucarsel-Powell did not give the two week’s notice required under a 2015 policy. But the lawmakers said the HHS denial violated a newly amended law that says members of Congress must be given access to facilities housing unaccompanied migrant children. The congresswomen say they decided to visit in the wake of news that the government plans to expand the facility, which they described as “cramped” and “prison-like” during an earlier visit.
