The Justice Department secretly obtained two months of telephone records of reporters and editors for The Associated Press in what the news cooperative's top executive called a massive and unprecedented intrusion" into how news organizations gather the news. The records obtained by the Justice Department listed outgoing calls for the work and personal phone numbers of individual reporters, for general AP office numbers in New York, Washington and Hartford, Conn., and for the main number for the AP in the House of Representatives press gallery. In all, the government seized the records for more than 20 separate telephone lines assigned to AP and its journalists in April and May of 2012. The government would not say why it sought the records. Officials have previously said in public testimony that the U.S. attorney in Washington is conducting a criminal investigation into who may have provided information contained in a May 7, 2012, AP story about a foiled terror plot. The story disclosed details of a CIA operation in Yemen that stopped an al-Qaida plot in the spring of 2012 to detonate a bomb on an airplane bound for the United States. Prosecutors have sought phone records from reporters before, but the seizure of records from such a wide array of AP offices, including general AP switchboards numbers and an office-wide shared fax line, is unusual.
