Washington Examiner:

Platte River Networks, the company that managed Clinton's email network after she stepped down from her post as secretary of state, indicated it transferred data off the original server in mid-2013.

An attorney for Platte River said there is likely "no useful data" remaining on the server.

But the Clinton campaign has suggested the former secretary of state did not erase emails she deemed personal until January of this year, raising questions as to where the emails were located when her staff sifted through them to determine which were related to her government service.

A Clinton spokesman did not return a request for comment, nor did an attorney for Platte River Networks.

The discrepancy further obscures the timing of Clinton's decision to erase 30,000 emails she claimed were unrelated to State Department business.

Dr. Marcus Rogers, head of computer information technology at Purdue University, said the fact that the data was migrated off Clinton's server in 2013 doesn't mean it was erased from the server at that time.
