He was threatened with his job if he kept asking specifically about Trig. But that doesn't keep him from asking about Trig from a round about angle. Like 'asking questions' about hospital records.
I've emailed [Adam Bellow at Harper Collins] asking him about the fact-checking process for "Going Rogue." Getting an on-the-record confirmation that, for example, Harper Collins reviewed the medical records proving Palin's multiple medical stories (including corrected hospital records by her own account) would be a useful piece of information. [emphasis mine]
Shorter Sully: Is Trig really the birth son of Sarah Palin?
Even shorter answer: Yes.
Follow up: Are you sure?
Retort: Even without looking at the records. Yes.
*The one line summery of the review: I still have hopes for Sarah Palin, provided she starts listening to what I have to say. Credit for the line goes to Joshua Livestro.
