It seems that a government agency wanted to keep a very close eye on her, and had actually planted evidence on her computer that they could later use to discredit or perhaps incriminate her or whoever they chose to paint as her sources.

Just when you think Attkissons imagination might be running away with her comes wave after wave of evidence that both her CBS computer and personal iMac were repeatedly hacked and its files accessed, including one on Benghazi. A consultant hired by CBS reached the same conclusion.

And an inspection revealed that an extra fiber-optics line had been installed in Attkissons home without her knowledge.
