Hunter will step down from the board on Oct. 31, according to a statement released by his lawyer, George Mesires. 

"Hunter always understood that his father would be guided, entirely and unequivocally, by established U.S. policy, regardless of its effects on Hunter's professional interests," reads the statement. "He never anticipated the barrage of false charges against both him and his father by the President of the United States." 

"Under a Biden Administration, Hunter will readily comply with any and all guidelines or standards a President Biden may issue to address purported conflicts of interest, or the appearance of such conflicts, including any restrictions related to overseas business interests," the statement continues. "He will continue to keep his father personally uninvolved in his business affairs."
