Baker administration says it is investigating allegations

The state’s chief advocate for the deaf and hard of hearing allegedly told staff members that he wore robes resembling Ku Klux Klan garb and made apparent Nazi salutes while he was a member of a controversial college fraternity three decades ago, according to employees and union officials.

Steven A. Florio, the commissioner of the state’s Commission for the Deaf and Hard of Hearing, told members of the agency’s staff in meetings and in an e-mail late last month that he was a member of Kappa Gamma Fraternity at Gallaudet University, a private university in Washington, D.C., for the deaf and hard of hearing.
