I do not believe he was lying when he responded, although he was clearly uncomfortable. As he said, if Wikileaks received material like that, they would release it. Obviously that was true, they got it and they released it.
What has been said is that Wikileaks did not receive all the material at the same time.
Here is one explanation for why he appeared to be lying or at least prevaricating. My own opinion is that they expected to receive them, but had not received all of them at that point.
Was Julian Assange lying when he denied receiving 280,000 classified US embassy cables in July 2010?No. In fact Mr. Bradley Manning is supposedly the primary source of the Cablegate document leak however the timeline of cables being submitted to the Wikileaks human rights volunteers indicate that more than one person had access to the documents and was providing them albeit at a slower rate than allegedly Mr. Manning did.
Also the Cablegate documents are only a small percentage of the evidence documentation that Wikileaks has in its possession. Prior to, during, and after the Cablegate documents being submitted, many hundreds of thousands of documents covering war crimes, drug drimes, racketeering, corporate terrorism et al. managed to find its way to Wikileaks, all of which has caused Wikileaks to buckle under an impossible work load.
The question at the time it was asked, probably could not have been answered any other way. The documents do not go to Assange's personal computer. Teams of people all over the world would have been sorting through them
for months, they probably still are.
So, while he knew, as he actually said within his answer, that there WERE Embassy Cables, because THAT WAS ONE OF THE CHARGES against Manning, he may not have yet known for sure that Wikileaks actually had them.
Iow, the charges against Manning at that time, in July, may have been the only reason Wikileaks had to believe they had them, but he could could not say 'yes' until they verified exactly what they had. I'm sure after the charges, they focused on finding them, and as he said, if they had them, they WOULD pubish them.
I see no lie in what he said. Just caution because he knew it was possible but he was not certain. That is why he did not say 'no', he said 'we have denied it' ~
Anyhow, thank you for providing the link I requested.
