But, even after reading only the Republicans’ memo, we can say two things. First, the F.B.I. and the Justice Department didn’t base their application to monitor Page entirely on Steele’s work. And, second, and more important, the Trump-Russia investigation didn’t begin with the Steele dossier. These two facts are there in that lonely paragraph on the fourth page of the Nunes memo. This is how it begins: “The Page fisa application also mentions information regarding fellow Trump campaign adviser George Papadopoulos, but there is no evidence of any cooperation or conspiracy between Page and Papadopoulos. The Papadopoulos information triggered the opening of an FBI counterintelligence investigation in late July 2016 by FBI agent Peter Strzok.”
