The U.S. Department of Homeland Security will allow Florida state officials to challenge the eligibility of a person to vote as part of its effort to purge non-citizens from its voting rolls. Florida election officials will have access to the SAVE (Systematic Alien Verification for Entitlements) database in an agreement that was announced Saturday by Florida Secretary of State Ken Detzner and the Florida Department of State. The announcement follows weeks of legal wrangling between the federal and state officials, a fight being closely watched in Colorado, Nevada, Michigan, and North Carolina — states the could ultimately swing November's presidential election.

"Florida voters are counting on their state and federal governments to cooperate in a way that ensures elections are fair, beginning with ensuring the voter rolls are current and accurate," Detzner said in a statement. "Now, we have a commitment to cooperate from DHS and we look forward to a partnership that improves our election process."

Details of the agreement were not immediately available, and it was not clear when Florida would begin checking its voter rolls against the database, which lists those who are legally in the United States on either visas or "green cards" but not eligible to vote. Today, 32 states have in place varying degrees of voter identification laws, according to the National Conference of State Legislatures
