“It is an extraordinary honor to follow in the footsteps of such a fine, gifted and truly legendary public servant as Gary Sasse,” Simmons, said in a statement.

“I will do everything I can to uphold the high standard he has set with his keen analysis of state fiscal policy, and his persuasive, even-handed voice for a more stable and prosperous Rhode Island,” he said.

Mayor David Cicilline said Simmons would be missed, but he would leave behind a legacy of fiscal integrity.

“John has been an invaluable member of my team from the very beginning,” Cicilline said in a statement. “His vast experience, financial expertise and keen understanding of the intricacies of public finance have helped put our city government on the strong financial footing needed to accomplish my ambitious goals for the city.”
