Trump's attacks on me baseless, says Biden's son
Joe Biden's son Hunter has rejected assertions by US President Donald Trump and his Republican allies that he did anything wrong in engaging in foreign work in Ukraine and China.
Hunter Biden slammed a "ridiculous conspiracy idea".
Former US vice-president Joe Biden is a frontrunner in the 2020 presidential contest.
Hunter Biden conceded he may have made a mistake for failing to see the political repercussions. But he added: "Did I make a mistake based on some ethical lapse? Absolutely not."
He also acknowledged he would not have been named on the board of a foreign company if his last name were not Biden.
"I don't think there's a lot of things that would have happened in my life if my last name wasn't Biden," he said.
Mr Trump has targeted Hunter Biden for his work in Ukraine and China, making baseless claims of corruption.
