Obama called a liar as US rivals trade blows
Mitt Romney (pictured) has branded Barack Obama a "liar" as the smouldering US presidential election campaign finally caught fire.
Mr Romney, the Republican hopeful, attacked Mr Obama for his campaign's advertising blitz trashing the former management consultant's career.
"It's time to set the record straight about Mitt's record and dispel Obama's lies," the Romney campaign said.
"When a president doesn't tell the truth, how can we trust him to lead?" said a Romney television advertisement accusing Mr Obama of dishonesty over claims that Mr Romney was a profiteer responsible for outsourcing jobs to China while at the helm of Bain Capital.
The fightback from Mr Romney -- by far the toughest attacks of the campaign so far -- came after several prominent Republicans and businessmen, including Rupert Murdoch, had urged the Romney campaign to go on the offensive against Mr Obama.
Just hours after the Romney advert was released, however, the Obama team accused Mr Romney of lying about when he stopped working for Bain.
Mr Romney has contended that he stopped working at the venture capital firm in 1999. Documents filed with the Securities and Exchange Commission, however, show Mr Romney was nominally in control of Bain Capital until 2002.
The Obama campaign has targeted several Bain Capital deals that took place after 1999, blaming Mr Romney for causing lay-offs, a charge that two independent fact-checking groups have agreed are misleading. (© Daily Telegraph, London)
