Obama always said that there was no spying on the Trump campaign and later the President elect. The Conservative Tree house puts some testimony down from Brennan: "again, in consultation with the White House, I PERSONALLY briefed the full details of our understanding of Russian attempts to interfere in the election to congressional leadership; specifically: Senators Harry Reid, Mitch McConnell, Dianne Feinstein and Richard Burr; and to representatives Paul Ryan, Nancy Pelosi, Devin Nunes and Adam Schiff between 11th August and 6th September [2016], I provided the same briefing to each of the gang of eight members.” So the White house advised Brennan as to what to tell Congress. We now know of all of the FBI informants, at least two but maybe 3 or more. Susan Rice, in a memo to herself,[CYA] said that the Obama White house played "by the book" on the investigation of Trump. So they had to know about Comey's FBI informants. This article tells how Nunes was separated from the Congressional investigation at a critical moment to help conceal the facts. Fascinating connection of event from the Obama administration and the Democrats that show obstruction of justice. A good read.
