Why did CBI spin the whole story towards terrorism ? [Season 1]

Its made clear to us many times that Bajpayee is from a regional party and they are against central ruling party. We also know that elections are around the corner.

Hathi Ram says to Ansari that "CBI was told to spin the story" presumably by higher political powers. But only political power that can command CBI is ruling party and they are against Bajpayee's party. Wouldn't it benefit ruling party more if Bajpayee is exposed trying to create unrest in country thus benefiting them in upcoming UP elections.
