TALLAHASSEE (AP) — Florida is demanding again that the federal government let it check the names of registered voters against a federal immigration database.

Secretary of State Ken Detzner on Tuesday sent a new letter to Department of Homeland Security Janet Napolitano saying Florida has all the information needed in order to gain access.

Florida wants to verify the citizenship status of thousands of voters on the rolls but the request has been turned down.

Recent letters from federal officials contend that Florida does not have the right registration numbers needed to identify voters. Florida last week filed a lawsuit demanding access to the database.

The state’s push to remove potentially ineligible voters has come under fire. Several groups on Tuesday filed a new lawsuit contending that the effort is discriminatory.
