Attorney General Martha Coakley is investigating donations made to to Lt. Gov. Tim Murray.
According to The Boston Globe, prosecutors from Coakley's office questioned two Chelsea Housing Authority employees last week about their political connections to Murray.
It was part of a criminal probe into whether former housing director Michael E. McLaughlin illegally turned the workplace into a political operation in order to help Murray win election, the Globe reports.
The employees testified under oath that they attended three fund-raisers for Murray, giving $100 each time and meeting the lieutenant governor.
McLaughlin was forced to resign last November after the Globe revealed his $360,000 annual salary.
