Newly released notes from the FBI's year-long investigation into Hillary Clinton's server suggests independent groups discovered potentially classified Clinton documents on a Romanian server while searching for evidence that her network had been breached.

The 100 pages of "302s," or summaries from interviews conducted during the FBI investigation, indicated an unidentified witness consulted Newt Gingrich in August 2015 about how to orchestrate an outside review of potential intrusions into Clinton's server. A "senior staff member" on the Senate Judiciary Committee was also involved, according to the notes.

Gingrich steered the witness to Judicial Watch, which put $32,000 behind the effort in February or March of this year. The project entailed scouring the "deep web" for evidence that Clinton's server, or that of her close confidante Sidney Blumenthal, was hacked.

The unnamed company who was tapped to lead the effort found "one sensitive Excel file listing the names of known or suspected jihadists in Libya" on a Romanian server. Some of the file had been written in Russia, the witness said.

A Romanian hacker breached Blumenthal's inbox in 2013 and exposed Clinton's private email address for the first time, forcing her to change her username. Clinton's allies have argued that hack did not compromise any of Clinton's files.

However, the potentially classified file "did not come from Blumenthal's server," the witness said. Upon discovering the list of names, the individual who had been hired to conduct the online investigation "became concerned he had found a classified document and stopped the project."

Judicial Watch did not immediately respond to a request for comment. The conservative-leaning group has several Freedom of Information Act lawsuits pending against the State Department in search of Clinton-related documents.
