Really though, the CIA and porky's intelligence community are extremely involved in numerous activities. If you haven't read about COINTELPRO, or paid attention to the election-rigging and infiltration of the governments of other countries, Voice of America propaganda, or the recent Vault7, the raid of the FBI in 1971, or Snowden, you should. Very few of the documents from leaks and raids get published, and those leaked so far reveal an extreme level of involvement. We could assume that they're just the tip of the iceberg. I'm just trying to say that if the CIA/FBI/NSA/ETC. used stormfront and other shit to build the alt-right it wouldn't be the first time.
