I don’t believe the TMZ report in its entirety, it doesn’t sound like the wording Romney would use.
My guess is that the woman does what a lot of incompetent people do: repeat stories so often enough, they are distorted from the original version and they start believing the distorted version.
TMZ is just a lefty hack bunch. For this story to have any legs whatsoever, the peddlers of this fertilizer need to have a credible and independent source that can show that Romney’s testimony regarding the value of Staples two years before it went public was substantially wrong or misleading. I seriously doubt they have that, or this would have been trotted out a long time ago in multiple Staples shareholder lawsuits.
