BOSTON — Attorney General Maura Healey says some alleged victims have approached her office as she investigates whether former Democratic Senate President Stan Rosenberg’s husband Bryon Hefner sexually abused men, including some with business before the Legislature.

Healey told WGBH-FM Thursday that alleged victims have come forward. Healey and Suffolk District Attorney Daniel Conley said earlier this month that they were prepared to open a separate, criminal investigation of Hefner, if that happens.

Asked about reports that the FBI is also investigating, Healey said Thursday “it’s a different investigation.” The FBI won’t confirm or deny it’s investigating.

Rosenberg has stepped down as president, at least temporarily, as the Senate Ethics Committee conducts its own investigation into Rosenberg and his staff.

Several men told The Boston Globe they were sexually abused by Hefner.
