And now...the kill stroke.
The OP links to a hack web site, which in turn links to a 25 second video on Twitter. The video is an excerpt from FBI Director Mueller's testimony to Senate Select Committee on Intelligence in February 2003.
Here is Mueller's full testimony:
2003 National Security Threats to the United States
As you can see when you read it for yourself, Mueller's testimony is entirely in relation to the domestic efforts of the FBI to protect our homeland from chemical, biological, and nuclear attacks by terrorists, particularly by Al Qaeda.
In his testimony, Mueller alludes to testimony given by Secretary Powell about WMDs in Iraq. Mueller himself is not confirming or testifying there are WMDs in Iraq. He merely states the testimony by Powell about WMDs in Iraq gave him concern those WMDs would get into the hands of terrorists.
The FBI concerns itself with domestic threats.
So the OP is a total lie. Mueller did not perjure himself.
Once again, the parroting hacks fell for another hoax.
And they will get back in line to be lied to again. Every time I have predicted this, I have never been wrong.
Like I said above, it already has, prole. You just fell for another hoax. And will again. And again. And again, ad infinitum.
You can't stop yourselves. You are mentally, emotionally, and psychologically incapable of stopping yourselves.
