BOSTON (AP) — Prosecutors pursuing sexual assault charges against the estranged husband of former Senate President Stan Rosenberg are seeking records on potential victims who spoke to attorneys hired by the Massachusetts Senate.

A motion filed Wednesday by Democratic Attorney General Maura Healey’s office in Suffolk Superior Court seeks information gathered by the Boston law firm Hogan Lovells for the Senate ethics investigation into Rosenberg, including interviews with potential victims.
