The AP, appropriately, reports:

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 incoming and outgoing calls, and the duration of each call, for the work and personal phone numbers of individual reporters, general AP office numbers in New York, Washington and Hartford, Conn., and the main number for AP reporters in the House of Representatives press gallery, according to attorneys for the AP...The government would not say why it sought the records. U.S. officials have previously said in public testimony that the U.S. attorney in Washington is conducting a criminal investigation into who may have leaked 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.

You can read that May 7 story here. President Obama's second term is quickly getting weighed down by these sorts of eminently avoidable scandals, and their liberal base isn't eager to defend them from critics, when they're committing shitty Bush-Administration-style acts like this.
