Collins, a Republican like his daughter, served five terms in the Maine House and Senate between 1970 and 1992, and also served as mayor of Caribou.
Condolences were quick to hail Collins for his public service and work as a businessman.
Senator Angus King, I-Maine, said "Don represented the best of Maine: a dedicated public servant, pillar of the business community and a loving husband and father. His contributions, in the county and across our state, will not be forgotten, and our prayers are with his family during this difficult time."
Former Maine senator Olympia Snowe, wrote: "We have such fond memories of Don over the years and have been great admirers of him, as well."
Since our first days working with him during his terms in the Maine State Senate where his selfless devotion, passionate commitment, and dedication of service to his nation and state were abundantly evident
