Well which part is fiction, and which truth? He didn't say? How would he know this?
Brit didn't elaborate, but there's a recent post about it. ABC did a piece on it which goes into some detail, which I haven't read yet. It's posted here: http://www.freerepublic.com/focus/f-news/1211441/posts
this is what I picked up from the article...
Gary Killian, who served in the Guard with his father and retired as a captain in 1991, said one of the memos, signed by his father, appeared legitimate. But he doubted his father would have written another, unsigned memo which said there was pressure to "sugar coat" Bush's performance review.
that was all it said...
