Outgoing state Treasurer Steve Grossman supports his successor's proposal for an independent budget oversight agency in Massachusetts.
Fellow Democrat Deborah Goldberg, who will succeed him as treasurer on Jan. 21, proposed a state version of the Congressional Budget Office.
Incoming Gov. Charlie Baker, a Republican, supports the idea although House Speaker Robert DeLeo, D-Winthrop, is skeptical.
"I think it's a terrific idea," Grossman said on Boston public radio station WGBH, adding that 44 states have such an independent agency.
"I think having an independent agency that takes a look at budgets and budget proposals and expresses a strong opinion about them, pro or con, is a good way to create more transparency in government. I think Deb Goldberg's on to something."
Grossman, who served one term as treasurer, gave up his seat in an unsuccessful run for governor.
