On Sunday, Trump disputed the idea there was any hack at all. "I notice, anytime anything wrong happens, they like to say the Russians are—[Hillary Clinton] doesn't know if it's the Russians doing the hacking. Maybe there is no hacking," Trump told moderator Martha Raddatz of ABC News. "But they always blame Russia. And the reason they blame Russia because they think they're trying to tarnish me with Russia. I know nothing about Russia."
It's the second time in two debates that Trump has declined to acknowledge that the hacks, mostly on Democratic targets, are real, much less that Russia is behind them.
"I don't think anybody knows it was Russia that broke into the DNC. She's saying Russia, Russia, Russia, but I don't—maybe it was. I mean, it could be Russia, but it could also be China," he told NBC's Lester Holt on Sept. 26. "It could also be lots of other people. It also could be somebody sitting on their bed that weighs 400 pounds, OK?"
A little more than 48 hours before Sunday's debate, the intelligence community and the Department of Homeland Security issued a joint statement that left little doubt the hack originated in the Kremlin.
"The U.S. Intelligence Community (USIC) is confident that the Russian Government directed the recent compromises of e-mails from US persons and institutions, including from U.S. political organizations."
The statement added, "We believe, based on the scope and sensitivity of these efforts, that only Russia's senior-most officials could have authorized these activities."
But Trump by then already had already been told privately by the intelligence community that the Russians were implicated—information he received weeks before the first debate.
On August 17, Trump got the first private briefing from U.S. intelligence officers to which he is entitled as the Republican nominee.
