We know Crowdstrike were responsible for DNC cybersecurity.

Was Crowdstrike one of the outside contractors which was given access to NSA data regarding "about" queries, and did Crowdstrike act as a conduit to relay NSA information to the DNC?

To what extent was there a tripartite relationship between NSA, DNC, and Crowdstrike?

What explanation is there for the FBI to leave the examination of the DNC servers to Crowdstrike?

Did the FBI know that there was NSA sourced data on the DNC servers and not want to "find" it.?
