Norwalk police are investigating the reported theft of some campaign finance documents.

Republican state Senate candidate Rick Giordano claims his campaign finance reports were stolen from his sister's car over the weekend. The deadline to file those papers is Tuesday and Giordano says the break-in is suspicious. Esther-Marie Giordano is serving as her brother's campaign treasurer and was spending the night in Norwalk when the car was broken into.

Giordano, who is running against incumbent Senator Andrew McDonald (D-Stamford), calls the incident "an attack" on his campaign. McDonald says Giordana is "lashing out." The New York State Secretary of State's Office says if Giordano misses the deadline, he will be forced to pay a fine, but will not be forced to drop out of the race.
