Back in May 2012 the CIA, in conjunction with the British MI6 and Saudi intelligence, pulled off a coup - some double agents provided intel about the latest Al Qaeda in Yemen underwear bomb and volunteered to deliver the bomb itself; in the course of bringing that together, the Saudis also gleaned drone targeting information for some Al Qaeda-Yemen leaders.
Kudos! And this was all too good to keep quiet during a Presidential campaign, so the Administration leaked like a sieve. Unsurprisingly, this annoyed our allies, so the FBI felt obliged to investigate. And good luck to them, since the sources (as with the leaks about the raid on Osama or the cyberattacks on Iran) were clearly coming from Presidential image-polishers.
So a year has gone by and now we learn that rather than vex various White House operatives with tiresome questions about how much they spilled to the press about Obama's awesomeness the FBI managed to obtain a broad subpoena covering a number of Associated Press reporters. That flips the script! Back in the Plame days, the point of a leak investigation was to tie the Administration up in knots (actually, a bipartisan effort to tie Cheney up in knots); now the Administration is using leak investigations as a weapon to throw a (wet) blanket over the press.
