Gov. Gina Raimondo has vetoed a bill that would automatically give firefighters a lifetime tax-free accidental-disability pension if they develop a heart condition. Supporters of the bill – sponsored by Sen. Frank Lombardi, D-Cranston – argue it should be presumed that firefighters who have a stroke or heart disease suffered the ailment in the line of duty. But critics say the change would cost local taxpayers as much as $2.8 million a year and take away discretion from the State Retirement Board, providing the pensions even if the applicant was a smoker or overweight.
