From update posted above:
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.
There’s a lot to be said about this case.
I hope he testifies at a hearing.
