The Department of Justice is assembling a first-ever national voter database. It has demanded that states turn over their complete voter registration lists — loaded with private information such as driver's license and Social Security numbers linked to names, home addresses and dates of birth.

It has also turned the federal immigration database into what it calls a national “voter verification” tool to remove large numbers of voters from the rolls.
