Donald Trump’s sister described the US president as cruel and a liar whose lack of principles meant he could not be trusted, according to secretly made recordings published Saturday.

It was the latest unflattering insider account to target the president, only instead of a jilted aide or business associate, it was from one of his closest relatives.

Maryanne Trump Barry slammed her brother over his immigration policy that saw children separated from their parents at the border and sent to detention centers.

“All he wants to do is appeal to his base,” she said in recordings obtained by the Washington Post. “He has no principles. None.”

“His goddamned tweet and lying, oh my God.”

The recordings were secretly made by the president’s niece Mary Trump, who published last month a bombshell memoir of the “toxic family” that produced him.
