Russia-hoax has its roots before that - and it involves both Clintonista and elements of America’s intelligence community and FBI.
Some suspect that as early as 2011, The Obama administration had given access to the full NSA electronic database to “contractors” who were basically Democrat Party operatives. In 2015 it became obvious to NSA staff that political searches were being conducted against all Republican candidates. Such searches ramped up when Trump joined the race.
After an internal investigation, Admiral Mike Rogers head of the NSA (and the real hero of this filthy saga), shut down all access to such “contractors.” Brennan and Clapper immediately tried to have him fired.
Literally - THE NEXT DAY after access was denied, Fusion GPS and the Clinton team began to push “the dossier” and the lies contained in it, to the FISA Court to regain wire-tapping privileges, this time through the FBI.
The CIA also interfered with the 2004 election opposite GWB, so they’ve had even more practice.
