The White House says the president is ‘not involved’ in running his businesses. Ethics experts remain concerned

Donald Trump has been accused of “corruption, plain and simple” after it was revealed that a member of the Emirati royal family was behind a $500m investment into the Trump family’s cryptocurrency company.

Ethics experts say the deal – struck just days before the US president’s inauguration last January – amounts to a deep conflict of interest for the White House, amid calls for a congressional investigation into the transaction.

Months after the deal, the Trump administration announced that the United Arab Emirates would be allowed to import 500,000 of Nvidia’s powerful AI chips – overriding concerns that the deal could eventually allow China access to the technology.
