The emails were not intentionally destroyed to avoid a subpoena. Comey testified to this point.
THE FACT CHECKER | Trump is technically correct on the timeline, but Clinton’s staff had requested the emails to be deleted months before the subpoena...
Thank you for showing Clinton and her Staff violated the law. Once the subpoena was delivered all plans to destroy the documents should have ceased. They went ahead and destroyed them any way... A subpoena took precedence over their intent. In fact, the subpoena simply made them more intent on destroying them.
Not to worry - I am sure Huma probably has those deleted e-mails in her stash of over 650K.
