Fusion GPS was a legal business doing background research on candidates. It has always been known the Democrat Party AND the Republican Party both employed Fusion GPS for candidate research. The Democrat National Committee and the Campaign of Hillary Clinton paid for theirs. The Republican National Committee paid for theirs.
Steele worked for MI6 (British government spy group) for many years, and a lot of that work was in Russia. That is why Fusion GPS paid him to do background research on Russia and Trump. Clinton and the Democrat Committee did not know who Fusion GPS had hired to do the research and there was no reason for them to ask about that while it was going on. They did not hire Steele, Fusion GPS did.
Steele's contacts in Russia gave him the information now known as the Steele Dossier.
I believe the facts are that the Washington Free Beacon, not the Republican Party or any of its sub-organizations, initially retained Fusion GPS to perform opposition research against Trump. The Washington Free Beacon has asserted that the information it received from Fusion GPS was all based on public sources and included nothing from the "Steele Dossier."
Reciting the obvious truth that all campaigns perform opposition research, and that there are firms that specialize in such research, in no way mitigates the significance of this revelation.
The Obama administration hijacked the law enforcement authorities of the United States in order to drive the lie that Trump had colluded with Russia to subvert the election, when in fact the only election collusion with the Russians had been bought and paid for 50/50 by the Hillary campaign and the DNC; and that very collusion furthered the co-opting of the US Justice system by providing the "evidence" on which a FISA warrant was executed against Carter Page.
The entire "narrative" was a complete lie motivated simply by partisan Democrat interests; unyielding, maniacal hatred for Trump and his voters; and Obama's overweening ego. It is worse than anything Nixon ever considered and fully justifies DOJ investigation, prosecution to the limits of the law, and wherever possible within the law, sentences in Federal Prison.
