I would like to see the Democrats memo. The following from Chris Wallace seems to make sense that there is another side to the story. Not just the dossier was used for this FISA warrant.
Wallace said, “I think there are some parts of it that are damaging to the FBI and to the Trump investigation, raise questions about it. And there are some aspects of it that are striking to me, in terms of what it leaves out, what it omits. One other point that I think is important to make right at the start, is that you heard from Adam Schiff and some of the Congressional Democrats how damaging this memo was to national security, that basically, it gave up sources and methods. There’s none of that in here.”
He later added, “Certainly, the use of the dossier seems to have been improper. But we don’t know how big a role that played in the FISA warrant. … [T]he idea that the only evidence in the FISA warrant was the dossier seems highly unlikely. There’s another point I think is being overlooked here. Carter Page was not just some innocent babe in the woods who was being attacked by FBI. In 2013, this hasn’t been mentioned at all, in 2013, Russian intelligence agents tried to recruit Carter Page as an agent for the Russians in this country. In 2014, Carter Page — this was years before Donald Trump ran for president, Carter Page was the subject of a separate FISA warrant.”
