The CDC say the exact opposite of this, and there is no evidence that they have ever changed their minds from that conclusion.
You are right. The CDC says the exact opposite. But are you so blind to authority that you cannot conceive of the CDC making a mistake?
The CDC's report is totally based upon the fact that "witnesses" reported seeing two letters containing powder - the J-Lo letter and the letter opened by Stephanie Dailey on the 25th. Does that mean that both letters contained anthrax? NO. The evidence says otherwise.
What the CDC's report says is that the CDC uses a different standard for evidence. They don't concern themselves with the criminal case, only the medical case. And if people say there were two letters with powder in them, that's good enough for them. They evidently don't have the time or desire to figure out if both had anthrax. They leave that to the FBI.
