Of course they didn’t investigate. This isn’t the traditional FBI anymore. This is the new weaponized FBI, doing the work of Hillary and Barack. Spying on Americans, creating fictional records, destroying paper trails, entrapment of political enemies. They don’t have time for that other stuff anymore.
Tea Partiers are terrorists, after all.
Disband the FBI.
Failed to investigate? How do we KNOW they didn’t actually GROOM him, egg him on, and even supply him with the AR-15, ammo and assure him he wouldn’t be shot. Howcome he’s still breathing? To draw attention away from Mueller, Comey, McCabe, Obola, et al?
