Sarah Palin's husband Todd attacks biography for 'lies'
Sarah Palin's husband has condemned "disgusting lies" contained in a biography of his wife due to be released next week.
The Rogue: The Search for Sarah Palin, a book by Joe McGinniss, alleges Mrs Palin had an affair in the 1990s, and has used cocaine, US media report.
It also claims the former Alaskan governor had a one-night stand with US basketball star Glen Rice.
Mr McGinniss moved into the house next door to the Palins in 2010.
The move prompted Mrs Palin to erect a fence between the houses to protect her privacy after news that Mr McGinniss had signed a book deal.
Mrs Palin, a potential 2012 presidential contender for the Republican party, has not yet commented on the claims.
Excerpts from the book, due out next week, were first published in the National Enquirer.
In a statement, Todd Palin said the book was full of "lies" and "smears", and accused Mr McGinniss of being obsessed with his wife, according to ABC News.
"This is a man who has been relentlessly stalking my family to the point of moving in right next door to us to harass us and spy on us to satisfy his creepy obsession with my wife," he said via a Sarah Palin campaign aide, the network reported.
"His book is full of disgusting lies, innuendo, and smears. Even The New York Times called this book 'dated, petty,' and that it 'chases caustic, unsubstantiated gossip."
According to US media reports, the book claims Mrs Palin had a six-month affair in the 1990s with Brad Hanson, Todd Palin's business partner at the Polaris snowmobile store in Big Lake.
Mrs Palin has previously denied the allegation.
Mrs Palin also allegedly had a fling with former NBA player Glen Rice in 1987 when he was in Alaska for a basketball tournament, a year before she eloped with Todd, the book says.
At the time, the young Sarah Heath was working as a sports reporter for the Anchorage TV station KTUU.
It also alleges that the former former Republican vice-presidential candidate snorted cocaine off a 55-gallon drum while on a snowmobiling trip with friends, and smoked marijuana with a professor at Mat-Su College in Alaska.
Mr McGinniss is known for his 1968 book on Richard Nixon, The Selling of the President.
