“Congress must demand greater transparency before providing further funding for immigration enforcement, border militarization, detentions, and deportations to protect against wasteful government practices, violations of domestic and international law, and other abuses of authority carried out in secret. Fundamental transparency demands include: ordering DHS to publish a quarterly report on all family separations that have occurred at the border; requiring the DHS Office of Inspector General (OIG) to conduct a prompt investigation into all cases of family separation and treatment of asylum seekers; and demanding CBP disclose information on all policies and guidelines relating to family separation that are of interest to the public. Congress also must demand compliance with existing transparency obligations relating to the government’s immigration detention system.”
