California's reporter's privilege explicitly protects (1) "[a] publisher, editor, reporter, or other person connected with or employed upon a newspaper, magazine, or other periodical publication or by a press association or wire service, or any person who has been so connected or employed" and (2) "a radio or television news reporter or other person connected with or employed by a radio or television station, or any person who has been so connected or employed." Cal. Const. art. I, § 2(b). Consequently, it is unclear whether it protects other types of journalists, such as book authors.
