On October 14, 2020, the New York Post published articles containing purported emails of unknown authorship which suggested that Hunter Biden provided an "opportunity" to Vadym Pozharskyi, an advisor to the board of Burisma, to meet his father, then-Vice President Joe Biden.[10][11][12] Joe Biden stated in September 2019 that he had never spoken to his son about his foreign business dealings.[13] His presidential campaign denied such a meeting took place and stated the New York Post had never contacted them "about the critical elements of this story".[14] Michael Carpenter, Vice President Biden's foreign policy adviser in 2015, told The Washington Post that he had accompanied Biden during all of his meetings about Ukraine and that, "He never met with [Pozharskyi]." He added, "In fact, I had never heard of this guy until the New York Post story broke."[15] One of the purported emails showed Pozharskyi saying he would share information with Amos Hochstein, a State Department advisor close to Vice President Biden, though Hochstein stated, "The Republican Senate investigation subpoenaed all my records, including emails and calendars and found no mention of this man. I led the US energy efforts in Ukraine and never even heard of him before yesterday."[16] The New York Post published images and PDF copies of the alleged emails, but their authenticity and origin have not been determined.[17] According to an investigation by The New York Times, editors at the New York Post "pressed staff members to add their bylines to the story", and at least one refused, in addition to the original author, reportedly because of a lack of confidence in its credibility. Of the two writers eventually credited on the article, the second did not know her name was attached to it until after The Post published it.[18] In its opening sentence, the New York Post story misleadingly asserted "the elder Biden pressured government officials in Ukraine into firing a prosecutor who was investigating" Burisma, despite the fact that Shokin had not pursued an investigation into Burisma's founder.[15] The opening sentence also misleadingly stated that Hunter Biden introduced his father to Pozharskyi, but the purported email from Pozharskyi only mentioned an invitation and "opportunity" for the men to meet.[19][20]
