Greenfield details how the dossier was used to astroturf and create a demand for an investigation, which ultimately resulted in Sessions’ recusal and the appointment of a special counsel. He reminds us that the Obama administration had done such stuff before, spying on congressional opponents on the Iran Deal. (Recall how that spying was used to tar Congresswoman Jane Harmon); giving money to non-profit organizations to spur the media coverage, whispering tidbits to complaisant media shills, and smuggling billions to Iran. And, as he notes, there was the IRS shutdown of conservative groups (for which they finally apologized this week) and the lies about Libya.
Notably, when they thought the Russia “collusion” fairytale was not gathering enough steam, Steele personally briefed David Corn, the same propagandist who confected the story that Valerie Plame was a covert agent deliberately targeted by the Bush Administration as payback against her husband Joe Wilson. 
But even more damning is the fact that Hillary herself started tweeting about the dossier shortly after GPS was hired -- even though she claims she knew nothing about it.
The first FISA request was made in June and was turned down. In July Fusion GPS was hired. According to James Comey, the FBI began investigating “collusion” reports in July of 2016, Beginning on August 15, Hillary started tweeting about Trump and Russia. She tweeted again on September 7, September 26, October 7, October 25, October 31. The second request was made in October. It was on October 31 when Corn, now at Mother Jones “broke the story of a ‘veteran spy’ who gave the FBI information on Trump’s alleged connections to Russia.” It wasn’t until Buzz Feed published the dossier that we could see how preposterous the story was. Mother Jones was just a small part of the media collaboration in spreading the manure -- Slate worked it also, and larger outlets got involved.
Former CIA case officer Lee Smith reveals how shoddy was the dossier: 
The dossier was designed to dig up “dirt” on Trump and his associates, but, more to the point, it was clearly intended from the start to do so by manufacturing and nurturing a Russian angle. It sought to discredit Donald Trump and to deceive the public, which suggests that Trump has been right all along regarding something like a conspiracy against him which included the active participation of the FBI and possibly other national security agencies.
The president also comes across as credible vis-à-vis his critics because of what has become evident since the dossier was surfaced. The clearly politically motivated multiple investigations carried out so far in which no rock has been unturned have come up with absolutely nothing, either in the form of criminal charges or in terms of actual collusion with a foreign government. And, one might add, there has been little in the way of evidence to sustain the charge that Russia sought to influence the election and might even have succeeded in doing so. But there is one thing new that we do know now: Russiagate began within the Clinton Campaign headquarters. 
Trey Gowdy tweeted: “Did FBI rely on a document that looks like the National Enquirer prepared it?” Looks that way. Andrew McCarthy at National Reviewtweets “Trump DOJ should declassify & disclose FISA app to show what representations were made to court about source of dossier claims.”
That seems uncontestable.
