Gov. Arnold Schwarzenegger's administration is refusing to release documents that reveal the level of its involvement in crafting a controversial and lucrative vehicle fleet contract that allowed only one major auto manufacturer - General Motors - to secure the deal, the San Jose Mercury News reports. State Sen. Dean Florez, D-Bakersfield, had asked for the documents following a hearing in July during which he expressed concern over the contract, especially because GM is a longtime major contributor to Schwarzenegger's private charities and political campaigns. Florez has also asked the administration to turn over a log of the documents that would provide the following details: subject of discussion, date of document, type of document, and names of people who wrote, responded to or who were sent copies of the written materials. Schwarzenegger spokesman Aaron McLear said the governor's office received Florez's latest requests, were reviewing them, but did not have a response. According to the San Jose Mercury News, Schwarzenegger's legal affairs secretary, Andrea Lynn Hoch, said the administration has a legal right, under the government code, to withhold internal records that "reveal the deliberative process within the administration," according to a letter she wrote this week to Florez.
