A timeline of the Fusion GPS dossier

Good investigative reporting by Chuck Ross at The Daily Caller:

FINALLY, A Definitive Timeline Showing When Clinton, DNC Started The Russian Dossier
There has been much confusion in the media — and thereby, the public — about who funded the infamous Trump dossier. Some outlets have incorrectly reported that Republicans began financing the dossier before the Clinton campaign and Democratic National Committee took over last Spring.

But that is incorrect. Democrats are solely responsible for the dossier, which was passed around by their research firm, Fusion GPS, to Beltway reporters and select lawmakers during the heat of the presidential campaign.

Here is the definitive timeline of how it all transpired.

Oct. 2015: It was reported late Friday that the Washington Free Beacon, a conservative website funded by GOP mega-donor Paul Singer, hired Fusion GPS to investigate Trump. Free Beacon’s editor said Friday that the research was standard opposition research and that it was not tied to the dossier work that would follow several months later. It is not clear what, if anything, Singer knew about Free Beacon’s hiring of Fusion. The hedge fund manager was Florida Sen. Marco Rubio’s biggest backer.

Much much more at the site. Chuck's work forms the definitive timeline of what happened when and who was involved. Runs through 2015 to October 24th, 2017 - lots of links to corroborating evidence.
