I don't think we know a fraction of what was really going on during the Obama years.
Here's a very strange tidbit from the Comey book tour on Attorney General Lynch.
Comey writes that he felt obligated to take more of a personal role as the public face of the investigation rather than deferring to then-Attorney General Loretta Lynch – in part because of something involving Lynch that he cryptically refers to as a “development still unknown to the American public to this day.”
In early 2016, the U.S. government became aware of information from a classified source, and “the source and content of that material remains classified as I write this,” according to the book.
“Had it become public, the unverified material would undoubtedly have been used by political opponents to cast serious doubt on the attorney general’s independence in connection with the Clinton investigation,” Comey writes, without further elaboration.
What exactly was going on during the Obama years?
Why was there "classified information" from a classified source about the Attorney General? Why is the source of this information still classified?
The obvious answer is that it comes from an investigation that is, in theory, still ongoing, and likely involves the Clintons. It could very well be something related to Uranium One. Or something we haven't even heard of.
And it involved contacts between figures in Clintonworld and the Attorney General of the United States. Problematic contacts.
If it involved Trump, we would already know about it. But investigations involving the Clintons get buried. And stay buried.
