"We are not involved in decisions made in connection with criminal investigations, as those matters are handled independently by the Justice Department," spokesman Jay Carney said.
Rep. Darrell Issa, R-Calif., chairman of the investigative House Oversight and Government Reform Committee, said on CNN, "They had an obligation to look for every other way to get it before they intruded on the freedom of the press."
Sen. Patrick Leahy, D-Vt., chairman of the Senate Judiciary Committee, said in an emailed statement: "The burden is always on the government when they go after private information, especially information regarding the press or its confidential sources. ... On the face of it, I am concerned that the government may not have met that burden. I am very troubled by these allegations and want to hear the government's explanation."
The American Civil Liberties Union said the use of subpoenas for a broad swath of records has a chilling effect both on journalists and whistleblowers who want to reveal government wrongdoing. "The attorney general must explain the Justice Department's actions to the public so that we can make sure this kind of press intimidation does not happen again," said Laura Murphy, the director of ACLU's Washington legislative office.
Rules published by the Justice Department require that subpoenas of records of news organizations must be personally approved by the attorney general, but it was not known if that happened in this case. The letter notifying AP that its phone records had been obtained through subpoenas was sent Friday by Ronald Machen, the U.S. attorney in Washington.
William Miller, a spokesman for Machen, said Monday that in general the U.S. attorney follows "all applicable laws, federal regulations and Department of Justice policies when issuing subpoenas for phone records of media organizations." But he would not address questions about the specifics of the AP records. "We do not comment on ongoing criminal investigations," Miller said in an email.
