New Jersey's health commissioner on June 2 sued the operators of a controversial federal immigrant detention center, saying they barred health inspectors from critical areas of the facility. State Health Commissioner Raynard Washington said that, when his team tried to inspect Newark's Delaney Hall in late May, they were only allowed access to the privately run U.S. Immigration and Customs Enforcement facility's food services area, according to the 18-page lawsuit filed in state Superior Court.
