The video (above) was shared with POLITICO and appears to show words being deleted from her files without her control.

In her new book, "Stonewalled," Attkisson details how her computers were hacked in late 2012 during her reporting on Benghazi. Attkisson alleges that government agencies were behind the attack, and also claims that her TVs and phone were tampered with. Someone she knows finds a "stray cable" attached to her FiOS box, which can be used to download data.

There is no way to confirm from the video alone that a hack is actually taking place, and there's reason to doubt that Attkisson was hacked at all. In a recent post for Vox, TImothy B. Lee demonstrated how Attkisson's so-called "evidence" isn't necessarily anything more than the "routine technical glitches that everyone suffers." Nevertheless, Attkisson's decision to release the video suggests she plans on using it to make her case. Attkisson will give her first television interview to Bill O'Reilly, of Fox News, on Monday.

As previously reported, Attkisson left CBS News in March after more than two decades with the network, citing frustrations with what she saw as the network's liberal bias, an outsize influence by the network's corporate partners, and a lack of dedication to investigative reporting. Sources at the network told POLITICO she increasingly felt that her work was no longer supported and that it was a struggle to get her reporting on air.
