Rothschild, who is married to French-British banking heir Sir Evelyn de Rosthchild, has previously denounced Obama as a 'loser' who was 'going to bankrupt America.'
She has also disparaged Obama by suggesting that he had no qualifications and was elected based on his race.
'The fact of [Obama's] personal story of being half black and all that is a wonderful, inspiriting story,' said Rothschild in 2011, while supporting Republican John Huntsman's 2012 presidential bid. 'But it doesn't qualify him to be president.'
