"Arizona's mining country lost one of its native daughters today with the passing of Governor Mofford," said Senator McGuire.
"Her wit, humility and energy were well known throughout the district where she grew up and whenever you saw her, whether at an event or around town, you knew you were in for a treat.
"I was privileged to get to know Governor Mofford over the years, to learn from her political advice and to call her my friend.
"Her tenacity and grace exemplified the spirit of Arizona. She was a special person and a rare leader who will be deeply missed."
