Rhode  Island lawmakers are busy trying to hammer out the new state budget.  House Speaker Nicholas Mattielo says the legislature's revised version of Governor Gina Raimondo's eight-point-six-billion dollar budget will be unveiled next week.  Lawmakers are taking a closer look at several portions of the governor's budget plan, including a new sweeping Rhode Works infrastructure proposal that among other things would begin charging tolls for large commercial truck drivers.  There is also a pension agreement that plans to end a four-year battle between the state and several unions over pension overhauls for state employees.
