Donald Trump's sister Maryanne Trump Barry condemns Ivanka and Eric in new secret recordings

New secret recordings have been unearthed of Donald Trump's sister Maryanne Trump Barry condemning the US President and his children.

Donald Trump's niece Mary Trump released the audio clips to MSNBC on Saturday while promoting her new book Too Much and Never Enough: How My Family Created the World's Most Dangerous Man.

In the recordings, Maryanne denounces Donald's children Ivanka and Eric.

"Eric's become the moron publicly. Ivanka [doesn't] give a shit. She's all about her," Barry said.

"She's a mini-Donald, but yet he's besotted with her. He always has been. She's always been his favourite...

"And then you get Donald who won't do anything for anybody unless it's going to inure to his - I mean, he won't do any - publicly.

"I mean, if you - anything he did, he says, 'Look what I've done. Aren't I wonderful?' And he's as tight as a duck's ass. Just like dad was, really."

Maryanne also criticised Ivanka for her decision to post a photo to Instagram in 2018 of her and one of her children on the same day it was reported the Trump administration was separating children from their parents at the border.

"When that damn Ivanka puts this picture of the Madonna and child on Instagram when the big news of the day was how kids are being ripped from their families," Barry said, according to MSNBC.

She can be heard saying she "couldn't blame" comedian Samantha Bee who called Ivanka a "feckless c**t" for posting the picture at the time.

The latest recording comes only a week after Mary Trump released another clip in which Barry said Donald Trump had "no principles".
