The Pacific Resources Partnership Political Action Committee spent an additional $1.2 million from the end of the primary election to Oct. 22 in its advertising campaign against mayoral candidate Ben Cayetano.

The amount does not include $445,654.19 in unpaid expenditures made by the PAC, according to the latest PRP filing made today with the Campaign Spending Commission.

PRP’s tab so far this election is $2.8 million.

It spent $1.2 million up to the primary.

PRP is a trade name for the Hawaii Carpenters Market Recovery Program Fund, a partnership of the Hawaii Carpenters Union and the trade contractors that use unionized workers. Funding comes from the contractors who contribute based on the number of hours worked by unionized employees.

Cayetano has sued PRP, alleging its advertisements against him are distorted and false.
