The happy warriors at Conservative Treehouse believe some (or all) of the stories CNN has recently broken, and then retracted as misleading, were the result of mole hunters closing in on a leak source among the so-called Gang of Eight.
The Gang of Eight holds oversight on every covert intelligence operation going on around the world. The Go8 oversee the NSA, CIA, FBI, DNI, and every single intelligence unit and operation. The Go8 are the only group with oversight on the CIA action from Presidential Finding Memos authorizing covert operations.CTH guesses the leaker is Rep. Adam Schiff (D-CA), ranking minority member on the House Intelligence Committee. Since he works hard at being a jerk, it would be very sweet if it turns out they are correct and he can be busted for violating security. A perp walk would be a good look for Schiff.
On the other hand, John Hinderaker of Power Line is inclined to believe the leakers were Shiff's committee staff. Whichever, it's an ugly business.
