The U.S. Department of Homeland Security and the state of Maine on Friday continued working toward an agreement so state residents won't be prohibited from using driver’s licenses to board commercial airliners and enter federal buildings.

Gov. John Baldacci, D-Maine, is gathering more information for the Homeland Security Department, said David Farmer, the governor’s spokesman.

Laura Keehner, a Homeland Security spokeswoman, said on Friday afternoon that no decisions had been made.

Starting May 11, the federal government would force residents of Maine to use passports to board planes or enter federal buildings because the state did not comply with the Real ID program or ask for an extension.

The federal government also has not granted South Carolina an extension. New Hampshire was granted an extension on Thursday.

Maine's Legislature passed a law last year prohibiting compliance with the Real ID law, which was enacted in 2005 to thwart terrorism.

The issue has split the state’s congressional delegation. Republican Sens. Susan Collins and Olympia Snowe had encouraged Baldacci in February to ask Secretary Michael Chertoff for an extension. Baldacci waited until Wednesday to request the department not penalize the state.

Democratic Reps. Tom Allen and Michael Michaud have called on Congress to repeal the Real ID law.
