Barack Obama's campaign team has urged reporters not to get 'distracted' by a word after the US president was quoted using a profane term to tag rival Mitt Romney as dishonest.
Obama communications director Dan Pfeiffer does not deny Obama had used the word 'bullster' in a conversation with journalists from Rolling Stone magazine, and insists: 'Trust is a very important part of this election.'
An advance copy of Rolling Stone's Obama interview, due on newsstands next month around the time of the November 6 election, recounts a chat at the White House between the president and the reporters.
'As we left the Oval Office, executive editor Eric Bates told Obama that he had asked his six-year-old if there was anything she wanted him to say to the president,' the story recounts.
'After a thoughtful pause, she said, 'Tell him: You can do it'. Obama grinned. 'That's the only advice I need,' he said. 'I do very well, by the way, in that demographic. Ages six to 12? I'm a killer.'
'Thought about lowering the voting age?' Bates joked.
'You know, kids have good instincts,' Obama offered. 'They look at the other guy and say, 'Well, that's a bullster, I can tell'.'
US politicians - especially presidential candidates - usually refrain from using strong language in public, and Obama's reported use of a profanity quickly sped around news websites and social media.
There was no immediate reaction from Romney's campaign.
