The latter was never used by America's intelligence community to bolster its case for spying on American citizens nor was it the foundation for a year's worth of media coverage.
Then again, you get what you pay for. We now know Hillary Clinton and the Democratic National Committee paid as much as $9 million for the discredited dossier on Trump.
According to the Washington Post, a lawyer named Marc Elias, who represented both the 2016 Clinton campaign and the Democratic National Committee, had hired Fusion GPS, a DC firm working on behalf of the Russian government to soften sanctions at the time, to provide opposition research for them. The firm then hired a former British spy named Christopher Steele who reportedly purchased salacious rumors about Trump from the Russians.
Now, you might expect that the scandalous revelation of a political campaign using opposition research that was partially obtained from a hostile foreign power during a national election would ignite shrieks of "collusion" from all patriotic citizens. After all, only last summer, when it was reported that Donald Trump Jr. met with a Kremlin-linked Russian lawyer who claimed to be in possession of damaging information about Clinton, there was widespread condemnation.
Finally, we were told, a smoking gun tied the Trump campaign to Vladimir Putin. Former Democratic vice presidential candidate Tim Kaine went as far as to suggest that the independent counsel begin investigating treason.
Treason! Trump Jr. didn't even pay for or accept research.
The Clinton crew, on the other hand, did. They didn't openly push the contents of the dossier — probably because they knew it was mostly fiction. Instead, Fusion GPS leaked it to their friends in the media.
The dossier ended up in the possession of most major news outlets. Many journalists relied on Fusion GPS to propel coverage. BuzzFeed even posted the entire thing for Americans to read, even though it was more than likely that its most scandalous parts were hatched by a foreign government.
The memo dominated newsrooms that were convinced Trump was a Manchurian candidate. No fake-news story came close to having this kind of impact.
