House Speaker Nicholas Mattiello is going to face a Republican challenge for his seat representing District 15 in Cranston. Barbara Ann Fenton-Fung announced Monday that she's filed a notice of organization with the state Board of Elections which she says allows her to start fundraising and launch a campaign. She's the wife of Cranston Mayor Allan Fung. In a statement, Democrat Mattiello says he'll run on his record of accomplishment leadership.
