SACRAMENTO, California -- A document fished out of a California state university trash bin last week has prompted a state investigation into the university's foundation arm and its refusal to disclose details related to Sarah Palin's upcoming speech at the school. On Tuesday, California Attorney General Jerry Brown said his office would look into the finances of the California State University, Stanislaus Foundation, as well as allegations that the nonprofit organization violated public disclosure laws by keeping details of Palin's contract secret.
