Robert Hunter Biden (born February 4, 1970) is an American lawyer and lobbyist who is the second son of former U.S. Vice President Joe Biden. He co-founded Rosemont Seneca Partners, an international consulting firm, in 2009. Biden served on the board of Burisma Holdings, a major Ukrainian natural gas producer, from 2014 to 2019. He has been the subject of debunked right-wing conspiracy theories concerning his business dealings in Ukraine. President Donald Trump's alleged attempt to pressure the Ukrainian government to investigate Joe Biden and Hunter Biden by withholding foreign aid triggered an impeachment inquiry in September 2019. In October 2019, Biden resigned from the Board of Directors of a Chinese private investment fund he co-founded, BHR Partners, saying he wanted to avoid even the appearance of a conflict of interest while his father was running for president.
