The events occurred in September. Congress, particularly the Republicans in the House, have been investigating it since then and they've come up with . . . edits to talking points as the big scandal.
I'm not suggesting that Congress shouldn't investigate and that Obama should be left alone, just that conspiracy theories based on anonymous sources to Geraldo Rivera and Glenn Beck may not really be truthful given that all that the House Republicans, who would love nothing more than destroying Obama and Clinton, have come up with is TrackedChangesGate.
