Massachusetts Senate President Harriette Chandler is pledging not to reveal the identities of individuals who gave information during the Senate's investigation into former Democratic Senate President Stan Rosenberg and his estranged husband Bryon Hefner.
Chandler, also a Democrat, told reporters Monday the Senate granted confidentiality to those who aided the investigation.
Chandler's comments come as an attorney for the Senate has accused Democratic Attorney General Maura Healey of "fishing" for the identities.
Hefner is facing criminal charges of sexual assault, distributing nude photos without consent and criminal lewdness. He's pleaded not guilty.
Rosenberg resigned from the Senate in May after the release of an ethics report that found he failed to protect the Senate from Hefner.
Rosenberg hasn't been criminally charged but is the subject, with Hefner, of a civil lawsuit.
