Clue emerges as to why Democrats did not want FBI to examine their server
...The DNC certainly did not act like they were concerned about the breach. Did they fear that the FBI would shut down their operations for a few days to find the breach and deal with it? There could be other things they were trying to hide from the FBI. But their continued use of teh system they knew was breached suggest they were not that worried about it until they lost the election and started looking for excuses.
DNC CEO Amy Dacey learned of the breach in late April, but of the 27,500 DNC emails published by Wikileaks, fewer than 7,000 pre-date April 29. A Daily Caller News Foundation analysis of the published emails shows that the majority were written between May 5 and May 25 — after cybersecurity firm CrowdStrike was brought in to respond.
CrowdStrike replaced the software on all DNC computers in what it believed would put the issue to rest June 10 — a month after the DNC detected the breach. Furthermore, there is reason to believe the breach had already ended, with the last Wikileaks email written May 25.
