In two separate court filings Roger Stone is challenging the DOJ to produce evidence of their predicate claim the Russians “hacked” the DNC servers.
The first filing is a motion to compel [SEE HERE] and requests the DOJ provide unredacted documents to support their framework of evidence that Russian’s “hacked” the DNC.  The second filing is a motion to suppress [SEE HERE] any downstream evidence, extracted by the use of search warrants, built upon upon the predicate claim of Russians “hacking” the DNC.

In essence Roger Stone is challenging the U.S. government to prove the DNC was hacked by Russians; and further he is refuting the validity of the FBI using a private organization, Crowdstrike, as a valid investigative and determinative body.
The suppress motion argues it was the responsibility of the FBI to secure and investigate the hacking evidence and not rely upon the word of a private party hired by the DNC (an opposing political entity). If the government cannot prove the Russian’s hacked the DNC, and subsequently attempted to work with Wikileaks for the distribution therein, then the basis for government claims about Stone seeking to engage with Wikileaks diminishes.

If the DOJ and FBI are independently certain Russian’s hacked the DNC servers, there should be no issue in providing the evidence toward that claim. It will be interesting to see how the DOJ responds; and how the judge rules on the responsibilities of the FBI.
