Investigative journalist Sharyl Attkisson, a senior independent contributor to The Daily Signal, released video showing what she believes to be a hacker deleting data from her computer right before her eyes.

Attkisson began experiencing technological problems during her reporting of the 2012 terrorist attacks on the U.S. consulate in Benghazi, Libya, she writes in her new book, “Stonewalled: My Fight for Truth Against the Forces of Obstruction, Intimidation, and Harassment in Obama’s Washington.”

One September night last year while Attkisson — then with CBS News —  prepped for an interview with Thomas Pickering, chairman of the Benghazi Accountability Review Board, she watched as information in a document began disappearing before her eyes. The information, she writes, was “deleted line by line in a split second: it’s gone, gone, gone.”

Attkisson  grabbed her nearby iPhone and used it  to record the disappearances.

The data wipe occurred, Attkisson writes, as White House spokesman Eric Schultz and then-White House Press Secretary Jay Carney were “steaming over my Benghazi reporting.”

After the breach, Don Allison, a security specialist at Kore Logic, examined Attkisson’s iMac. Upon doing so, she writes in “Stonewalled,” Allison found “key evidence of a government computer connection” to her laptop.
