Trump's sister calls Ivanka 'mini-Donno' in new audio tapes

Donald Trump's older sister is heard sharply criticizing her brother and two of his children in a new set of recordings released by her niece, who recently wrote a book denouncing the US president.

In the recordings, former federal judge Maryanne Trump Barry is heard criticizing Ivanka Trump for posting a photo on Instagram of herself and her young son, amid a public outcry over the separation of migrant children from their parents at the country's southern border.

She continues saying that Ivanka is a "mini-Donno" and that her father is "besotted" with her, adding "she's always been his favorite".

Trump Barry can also be heard saying that the president's second son, Eric, has become "the moron publicly".
