G.R.U. is a military spy organization. It doesn't work for individual deal. Because Trump has spy back ground, so Russian took over the deal. But could Russian really manipulate US voters? I don't think so. What the Feds needed was an excuse to justify Trump's victory. Russia was just a scapegoat.

To send an unqualified man to the seat of President, they need a rigged election. In US, they pick up president by rigged election because they control the spy system.(FBI) And justify the result by poll because they control the media. (controlled by the Feds too) This time is particular one so they bought Russia to meddle the water.
