"In May 2013, at the President's direction, the Attorney General initiated a comprehensive evaluation of the Department of Justice's policies and practices governing the use of law enforcement tools, including subpoenas, court orders, and search warrants, to obtain information or records from or concerning members of the news media in criminal and civil investigations. As part of this process, the Attorney General convened a series of meetings to solicit input from a wide range of news media stakeholders, First Amendment academics and advocates, and Members of Congress. Based on this review, the Attorney General is making significant revisions to the Department's policies regarding investigations that involve members of the news media."
