Fox News correspondent Jennifer Griffin reported the latest from the Hillary Clinton campaign trail following the news that the FBI will continue investigating her private email server. 

Earlier today, FBI Director James Comey wrote in a letter to Congress that there is "pertinent" information regarding possibly "classified" information that needs to be re-examined.

Griffin reported from Cedar Rapids, Iowa, that the new information is not related to the recent WikiLeaks release of emails hacked from Clinton's campaign chairman John Podesta.

Griffin pointed out a new report by the New York Post, which stated that 33,000 emails deleted by Clinton might actually be recoverable.

She called this the "October surprise that the Clinton campaign never anticipated." Griffin said some reporters shouted questions at Clinton as she arrived in Cedar Rapids, but she ignored them.

Her running mate, Tim Kaine, was asked about it at a separate event, but wasn't aware of the report and seemed "flustered," Griffin explained.

Watch the report above and stay tuned to Fox News Channel throughout the day for further developments on this story.
