It's being widely reported that Warwick Mayor Scott Avedisian will step down to become the director of the Rhode Island Public Transit Authority.  Governor Gina Raimondo said on Tuesday that she recommended Avedisian for the position to the RIPTA board, which is scheduled to discuss and possibly vote on the appointment of a new CEO on Wednesday.  Avedisian himself has declined to confirm reports.  He has served as Warwick mayor since 2000, the longest term in the city's history.
