Hunter Biden, son of democratic presidential hopeful Joe Biden, details his work that Donald Trump has criticised

Hunter Biden, the son of former US vice president Joe Biden, pushed back for the first time on Sunday morning at the criticism he has received from Republican President Donald Trump about his work in Ukraine and China.

Hunter Biden intends to step down from the board of a Chinese company that has been the target of criticism on Oct. 31, according to the statement. He has received no profit from his time serving on the board of BHR (Shanghai) Equity Investment Fund Management Company.

Trump's accusations against Hunter Biden - which he has levied without any evidence - and his efforts to get officials in Ukraine to investigate, led Democrats in the US House last month to begin an impeachment inquiry into the president.

Joe Biden currently leads most public opinion polls in the Democratic primary and most polls in a hypothetical match-up between him and Trump in the November 2020 election.

Hunter Biden's attorney dismissed that his client had done anything wrong. He said while Hunter Biden was working at Bursima, the energy company in Ukraine, he faced no allegations of wrongdoing.

"Hunter undertook these business activities independently," his attorney George Mesires said in a statement. "He did not believe it appropriate to discuss them with his father, nor did he. Hunter always understood that his father would be guided, entirely and unequivocally, by established US policy, irrespective of its effects on Hunter's professional interests."
