FBI optimistic it can recover some data from Clinton server

The FBI may be able to recover at least some data from Hillary Clinton’s private email server even though there was an attempt to wipe it, two sources with direct knowledge of the process told NBC News on Tuesday.

The FBI is investigating the security of Clinton’s personal server and the thumb drives that contain emails related to her work as secretary of state during President Barack Obama’s first term. The Clinton campaign has previously acknowledged that there was an attempt to wipe the server before it was turned over last week to the FBI.

The FBI “will try to figure what’s there, how it got there and who put it there,” one of the sources said.

A team of intelligence community reviewers also looking at emails from the server have identified 305 documents that have been referred to their agencies for further consultation, State Department lawyers said in a court filing Tuesday intended to update a federal judge on efforts to release the emails.
