RICHMOND, Va. (AP) - A civil rights group has filed a federal lawsuit against Virginia election officials after the state's online voter registration system crashed Monday, preventing some Virginians from signing up to vote.

Local news organizations report that the lawsuit was filed Tuesday by the Lawyers' Committee for Civil Rights Under Law on behalf of Kathy and Michael Kern, a Charlottesville couple who failed to register by Monday's deadline after the registration website faced technical issues.
