WESTFIELD -- Former Pittsfield Mayor James M. Ruberto has resigned from the Westfield State University board of trustees.
Ruberto, who accompanied then-university President Evan Dobelle and 20 guests on a trip to Cuba last year, submitted a resignation letter to Gov. Deval Patrick in May without stating a reason, the Springfield Republican first reported on Tuesday.
Ruberto, who served four terms as Pittsfield's mayor, leaving office in 2011, joined the Westfield State board in June 2013, nearly three months after joining Dobelle and others on a trip to Havana that coincided with two exhibition games played by the school's baseball team, the Republican reported.
Dobelle, who also served as mayor of Pittsfield during the 1970s, resigned from the university post after six years in November, amid mounting criticism of his lavish spending as president, often on travel.
Details of the trip became public recently following investigations by the state Inspector General and state Attorney General's offices, both of which have challenged Dobelle's spending.
Attorney General Martha Coakley recently sued to recover nearly $100,000 in public funds allegedly spent by Dobelle on personal expenses.
Ruberto could not be reached Tuesday for comment.
Dobelle has maintained that his spending benefited the university and any personal items charged to WSU-related credit cards were later reimbursed.
