Republicans in the Arizona state senate, which authorized the inquiry, allocated $150,000 in state funds to pay for it â just a fraction of the projected overall cost, which is still unknown. The state senate had enough money in its operating budget to pay for the investigation, the Arizona Mirror reported in April, but chose not to pay the full price.
Instead, the effort is being paid for by private donors, who remain hidden from the public, according to a review by OpenSecrets and the Guardian. Arizona Republicans and Cyber Ninjas, the Florida-based company overseeing the review, have refused to say who is providing the rest of the money.
