State Dept. Can't Find Person Responsible for Controversial Video Edit

— -- The State Department said today that after a thorough investigation into the editing of an archived news conference about the Iranian nuclear talks, the agency ultimately cannot determine who is responsible.

During the December 2013 news conference, a reporter asked if the State Department ever knowingly lied about those secret talks, but later the entire 8-minute exchange was deleted from the agency's website.

State Department spokesman John Kirby said today that the investigation included a search of emails and documents as well as interviews with more than 30 current and former employees, none of whom could recall who asked for the edit to be made.

Kirby said the findings of that investigation will be shared with Congress and the State Department's Inspector General.

Initially a spokesperson at the State Department blamed the edit on a technical glitch, but soon after officials admitted the edit was intentional.

Kirby said today that a technical problem could still not be ruled out, saying that there is no evidence it was a nefarious act. He said it was possible the portion of video was deleted in order to fix a technical problem. Yet other copies of that same video, shot from the same camera, remain perfectly in tact with no glitches, as they have for over two years.

The conservative group Judicial Watch also filed a freedom of information lawsuit today against the State Department, asking for all documents related to the investigation.
