Penner wrote:The CIA's assessment that the Russians favored Trump was not based on any single piece of new intelligence, officials briefed on the matter told NBC News. Instead, it was the result of more stringent analysis of a growing body of circumstantial evidence more detailed than anything the public has seen.
Human sources, communications intercepts and other intelligence have allowed analysts to piece together the identities of some of the players, and the steps they took to hurt Clinton's candidacy while boosting Trump's, officials said.
The CIA also noted that while Russian hackers gathered information on Republicans, they didn't release any of it, the way they did with Democratic emails leaked to WikiLeaks. The Republican National Committee denies its systems were hacked, but the emails of individual Republicans were collected — something NBC News reported in October.http://www.nbcnews.com/news/us-news/why ... in-n695131The CIA also tracked a campaign of anti-Clinton news stories amplified by social media, some of which originated with Russian state media outlets, officials told NBC News
n October, DNI Clapper and Homeland Security Secretary Jeh Johnson issued an extraordinary joint statement that "the U.S. Intelligence Community is confident that the Russian Government directed the recent compromises of e-mails from US persons and institutions, including from U.S. political organizations."
One source familiar with the intelligence said it included profiles of some of the suspects with pictures, and could lead to eventual indictments of specific Russian actors, if the Justice Department decides to pursue them.
Still no sources other than the CIA saying they have sources. Well that's fine then. They should build their case and bring it to court.
