US President-elect Donald Trump's eldest daughter Ivanka Trump has denied that she will serve in her father's White House administration following his inauguration in January. In a family interview Sunday night with CBS's 60 Minutes, 35-year-old business woman and mother of three said she would not hold a formal administrative capacity in her father's cabinet. 'I'm going to be a daughter,' she said. 'I've said throughout the campaign that I am very passionate about certain issues. And that I want to fight for them.' Among the issues she said she would work toward are wage equality, childcare, education and women's rights.
