Teasing out these two large-scaled unknowns in order, Fusion GPS looms as a crossroads in the inquiry into Russian meddling by both the Trump and Clinton campaigns.

What Republican partisan hired Fusion GPS in 2015 in order to develop what became the former MI6 agent Christopher Steele’s dossier of alleged conduct by Donald Trump long before the 2016 campaign?

What Democratic partisan then paid Fusion GPS in order to take over and to exploit the Steele dossier beginning in June 2016?

Then again, Fusion GPS is also involved in the suspect conduct of Russian lawyer Natalia Veselnitskaya.
