The things his sister said might be untrue or exaggerated...
It's old news. And it's largely fiction.
Well, his sister did write a book. That's about the extent of the facts associated with that story.
You mean other than knowing George Allen for the last 20 years?
As for how much of the book is fact and how much is exaggerated, I really don't know. And to be honest, don't care that much.
The book is about Jennifer Allen's relationship (or non-relationship) with their father. From the excerpts I've read, it's not flattering to anyone in the family. But it's much along the lines of the books Patti Davis and Carrie Fisher wrote about their parents.
My personal opinion is that it's a bit of sibling rivalry. Jennifer never fit in with the football scenario. Her brothers did.
But, I've known George Allen as an adult. God help us all if we're judged for our behavior as teenagers 30 and 40 years ago.
IIRC, the RATS did try to bring this up in 2000 when the book came out. The book, the flag and other stuff will be on the forefront just like the National Guard and dancing naked on a bar was for W.
But, when there needs to be a response, Allen will respond. And I'm not afraid of his answer.
