Johnny Cash died in 2003
The daughter of late country star Johnny Cash has called the use of her father's name to endorse a US presidential candidate "appalling".
Country star John Rich implied Mr Cash would have backed Republican hopeful John McCain while appearing at a rally in Florida, according to media reports.
Writing on her website, Rosanne Cash called the remarks "presumptuous".
"Even I would not presume to say publicly what I 'know' he thought or felt," she added.
According to the Washington Post, Mr Rich, a member of the duo Big and Rich, told a crowd of supporters in Florida: "Somebody's got to walk the line in the country."
"They've got to walk it unapologetically. And I'm sure Johnny Cash would have been a John McCain supporter if he was still around."
The star then went on to sing Cash's hit, I Walk the Line.
Ms Cash, who is also a singer-songwriter, requested that in future: "My father not be co-opted in this election for either side, since he is clearly not here to defend or state his own allegiance."
"I knew my father pretty well, at least better than some of those who entitle themselves to his legacy and his supposed ideals," she added.
Grammy-award winner Cash sold over 90 million records and had hits with Folsom Prison Blues, Ring of Fire and Man in Black. He died in 2003, aged 71.
