Joe Biden’s son, Hunter Biden, said on Wednesday that the US attorney’s office in Delaware had opened an investigation into what he referred to as his “tax affairs”.

A Senate investigation earlier found that Hunter Biden had allegedly leveraged his family name to secure lucrative business deals. And attorney Rudy Giuliani claimed a laptop recovered from a repair shop in Delaware and belonged to Hunter Biden documented his foreign business dealings.

According to The Guardian, on Wednesday the Associated Press reported that a person familiar with the matter stated that the tax investigation into Hunter Biden concerned some of his Chinese business dealings, among other financial transactions, but “does not have anything to do with the laptop”.
