President George W. Bush snorted cocaine at the presidential retreat Camp David while his father was present, his former sister-in-law Sharon Bush alleges in a new book.
Ms Bush is quoted as saying: 'Bush did coke at Camp David when his father was president, and not just once either.'
The allegation is made in Kitty Kelley's new biography The Family: The Real Story of the Bush Dynasty, according to a report in Britain's Daily Mirror.
Other acquaintances quoted in the book say that as a 26-year-old National Guard, Mr Bush 'liked to sneak out back for a joint, or into the bathroom for a line of cocaine'. The book says the US president first used cocaine at university in the mid-1960s.
The Mirror quoted the White House as saying, 'This book appears to be filled with the same trash discredited years ago.'
When asked in 1999 if he did drugs, Mr Bush said: 'I've told the American people that years ago I made some mistakes. I've learned from my mistakes, and should I be fortunate enough to become president, I will bring dignity and honour to the office.'
