Hunter Biden arranged for a Burisma Holdings big shot to meet with his dad, Vice President Joseph R. Biden, in Washington in April 2015, a year after he joined the corrupt firm’s board of directors and garnered millions of dollars in payments from a Ukraine oligarch, an email shows.

The email, obtained and posted on Wednesday by the New York Post, cast doubt on Democratic presidential candidate Biden’s repeated assertions that he knew nothing of Hunter’s lucrative business ties in Moscow, Ukraine and China.

A second 2014 email from the same Burisma official, Vadym Pozharskyi, asked the newly empaneled Hunter Biden to “use your influence” to stop political and government attacks on the natural gas company.

Vice President Biden bragged in 2018 that he got the state prosecutor, Viktor Shokin, fired though he says it was for corruption, not to help his son.

The 2015 email, if verified, shows that Hunter Biden did in fact leverage his dad’s position as vice president to “cash in,” as two Republican senators charged in a report on his finances earlier this month.

Mr. Pozharskyi ranks high in the energy firm corporate structure under oligarch Mykola Zlochevsky.

President Barack Obama named Mr. Biden his point man on Ukraine after the Russian invasion of Crimea in February 2014. Three months later, Hunter Biden won a lucrative spot on the Burisma board, alongside his business partner, Devon Archer. Mr. Archer subsequently was convicted on fraud charges.
