Turns out, per the leaked minutes of CIA briefings of Congress, that leaders of both parties in Congress were explicitly briefed about the use of the tactic.
My guess is that Barack Obama would have been briefed like this too…if he’d been a senior enough member of the Senate to actually get to sit in on some of these committees.
Regardless, I’m not a fan of leaks like this in general. Especially when these leaks are motivated by politics. There were more than enough conveniently leaked documents under Bush (always leaked out of context so that they looked worse than they were) and it didn’t do anyone any good. I don’t like it any better now that it’s happening to Obama.
