Former deputy prime minister Barnaby Joyce has revealed that he does not believe official accounts explaining the assassination of US president John F. Kennedy. He tweeted his opinion about the November 22, 1963 murder on November 23. "Today is the 60th anniversary of the assassination of JFK, 35th President of the USA," he said. "65 per cent of a US survey don't believe the Warren Report that it was only Lee H. Oswald with a dodgy ex military Italian rifle from the 6th floor of the Texas Book Depository 81 metres away. "Nor do I." Online responses have met Mr Joyce with hearty scepticism over the conspiracy. One commenter was quick to respond "you also believed you were watching the Women's World Cup quarter-final live, too". Another commenter made a Jeopardy! reference saying "thanks, Alex. I'll take least surprising politicians who believe in conspiracy theories for $400". "You Special Envoy for the Doubt now Barnaby?" another said.
