The Department of Homeland Security wants access to the Federal Parent Locator Service, which is considered to be the government’s largest, most detailed database, ProPublica reports.The database, which Bethanne Barnes of the Administration for Children and Families called “the most powerful people-finder system that the U.S. government has,” exists so that the government can locate parents who owe child support if they move states or change their employment status. It holds the name, Social Security number, address, and pay of every single employed person in the country.The Locator Service also holds the names of every single child involved in a child support case, along with their gender, birth date, Social Security number, and family members. It also notes if they or their mother have experienced domestic violence—something that potential abusers within law enforcement would be able to see if given access to the database.Child support workers at the state level have expressed concern that employers will no longer report new hire information to them out of fear of DHS retribution, which in turn will bog down the child support system and hurt children and their parents in the process.“And if we’re not learning from employers when a parent who owes child support gets a new job, who loses in that situation?” said Kate Cooper Richardson, Oregon’s former child support program lead. “The one in five U.S. children who rely on consistent and regular child support.”It’s up to the Department of Health and Human Services to approve this access request. It has yet to comment.
