The Sacremento Bee:  “Sacramento County District Attorney Jan Scully’s probe into Isleton’s licensing of a medical marijuana farm has hardened into a legal war of wills as city officials say they’ll refuse to testify when called before a grand jury next week.  Scully subpoenaed City Council members and the city manager of the Delta hamlet April 13, after declaring in a letter that the city’s agreements with the medical marijuana grower likely ‘violate state and federal statutes’ and could subject local officials to prosecution.”
