Former Massachusetts Senate President Stan Rosenberg will also be a former Massachusetts state senator at the end of the week.
Rosenberg submitted a letter Thursday afternoon announcing that he is resigning from the Massachusetts Senate effective 5 p.m. Friday, May 4.
The one-sentence letter ends a career as a state legislator that began in 1986.
Rosenberg, 68, served as president of the Massachusetts Senate from January 2015 until December 4, 2017, when he stepped down amid allegations of sexual harassment and sexual assault against his civil-law husband, Bryon Hefner.
Rosenberg, a Democrat from Amherst, had originally hoped to regain his position as Senate President once an ethics investigation cleared him of wrongdoing.
But a scathing report released Wednesday undermined his standing among his colleagues, many of whom had stood by him until recently.
The report by a law firm commissioned by the Ethics Committee of the state Senate found that Rosenberg failed to rein in Hefner and gave Hefner improper access to his official email account, among other trappings of power. The governor, attorney general, and several state legislators called on Rosenberg to resign from the Senate.
