The letter, which was first reported by Reuters, told governors that their states are providing U.S. Immigration and Customs Enforcement (ICE) and other federal agencies "with frictionless, self-service access to the personal data of all of your residents," through a non-profit managed by state police agencies called the National Law Enforcement Telecommunications System, or Nlets. Nlets facilitates the sharing of state residents' personal data, in this case drivers' license data, between state, local, and federal police agencies.
