William Binney, who was Technical Director at the NSA and actually designed their surveillance capabilities, has advised me by email.
…NSA would have the actual hack on record, would be able to recognise the emails themselves and tell you exactly the second the transmission or transmissions took place and how they were routed. They would be able to give you date, time and IP addresses.
…But the report gives no evidence at all of the alleged successful hack that transmitted these particular emails, nor any evidence of the connection between the hackers and the Russian government, let alone Putin.
…Obama has been a severe disappointment to all progressive thinkers in virtually every possible way. He now goes out of power with absolutely no grace and in a storm of delusion and deceit. His purpose is apparently to weaken Trump politically, but to achieve that at the expense of heightening tensions with Russia to Cold War levels, is shameful.
