Who would spy on Hilary, and for what purpose?
Anyone who wanted leverage on the President of the United States of America.
HRC was the frontrunner even before the campaign season even started. MSM already had her in the White House before she even announced her bid for the Democrat Party nomination. But, according to Byrne, Maria Butina appears to have met one person connected to HRC and then dropped that. The focus then became all Republicans - Minor = Rubio and Cruz; Major - Trump.
The thought is that Hillary’s name was thrown in to make it look like Republicans weren’t the only ones being spied on.
Any FISA warrants for Hillary?
I bet not.
