AUGUSTA — Gov. Paul Le-Page’s administration is firing back at the federal government over its policy of putting welfare recipients’ photos on the cards used to access food stamps, which federal officials have warned could cause Maine to lose some program funding. In a Dec. 18 letter to the Food and Nutrition Service obtained by The Associated Press, Department of Health and Human Services Commissioner Mary Mayhew responded to several concerns raised by the agency last month and blasted officials for consistently putting up “roadblocks and barriers” in the state’s effort to prevent fraud and abuse.
