(Providence, RI) -- Rhode Island House Speaker Nicholas Mattiello is facing calls to resign from the state's Republican Party after the state board of elections ordered him to repay about 72-thousand dollars in campaign expenses. The board investigated a complaint filed by the state GOP that claimed Mattiello used his political action committee to spend much more than the allowable amount on his 2016 campaign. Republican Party Chairman Brandon Bell claimed in a statement that Mattiello would not be in office if not for the illegal activity. Mattiello told reporters on Wednesday that he made a mistake but did nothing intentionally wrong.
