PROVIDENCE, R.I. (AP) — An investment forum on the financial problems facing America's cities delivered a glimpse Monday of what Rhode Islanders could expect from a potential match-up between Gov. Lincoln Chafee and Treasurer Gina Raimondo in next year's gubernatorial race.

The independent governor and Democratic treasurer both delivered remarks to the more than 250 bond investment professionals attending a symposium in Providence on deficits and pension costs.

With firefighters protesting her appearance outside, Raimondo detailed the sweeping pension changes she crafted two years ago that saved the state billions by cutting benefits to many public workers and retirees. Public-sector unions and retirees are challenging the changes in court, saying they amount to an unfair breach of contract.
