The U.S. Justice Department plans to sue North Carolina over its restrictive voter identification law, The New York Times reported, escalating the federal government's efforts to stop states from limiting the rights of minority residents -- and some college students -- to cast their ballots. College students have been particularly affected by laws passed in various states -- including North Carolina -- that require voters to present photo identification at the ballot box, but do not recognize student identifications or IDs issued by public assistance agencies as acceptable forms.
