mhorndisk wanted an answer, I gave him one. He refuses to believe it. The subpoena that she allegedly violated was from a congressional committee investigating Benghazi. It asked for emails from her server related to that investigation. It did not ask for every blessed email on the server. If she had kept paper files her basement and they asked her to produce the relevant ones, she would not have to submit every file there. here is the subpoena:
http://benghazi.house.gov/sites/republicans.benghazi.house.gov/files/Kendall.Clinton%20Subpoena%20-%202015.03.04.pdf
(i haven't learned how to embed a pdf file or even if it is possible)
There is your answer. I know mhorndisk will not accept it. Nor will he read the subpoena for himself. He will rant and rave about Benghazi or Russia or the Clinton Foundation. The FBI said she did not commit a crime. What more do you want, the Spanish Inquisition?
Again, it true that the at least some of the emails were deleted after receiving the subpoena, but Hillary and her staff swore that they were unrelated to the Benghazi investigation. Read about it on Politifact:
