Hunter Biden introduced his father, then-Vice President Joe Biden, to a top executive at a Ukrainian energy firm less than a year before the elder Biden pressured government officials in Ukraine into firing a prosecutor who was investigating the company, according to e-mails obtained by The Post.

The never-before-revealed meeting is mentioned in a message of appreciation that Vadym Pozharskyi, an adviser to the board of Burisma, allegedly sent Hunter Biden on April 17, 2015, about a year after Hunter joined the Burisma board at a reported salary of up to $50,000 a month.

“Dear Hunter, thank you for inviting me to DC and giving an opportunity to meet your father and spent [sic] some time together. It’s realty [sic] an honor and pleasure,” the e-mail reads.

An earlier e-mail from May 2014 also shows Pozharskyi, reportedly Burisma’s No. 3 exec, asking Hunter for “advice on how you could use your influence” on the company’s behalf.

The blockbuster correspondence — which flies in the face of Joe Biden’s claim that he’s “never spoken to my son about his overseas business dealings” — is contained in a massive trove of data recovered from a laptop computer.

The computer was dropped off at a repair shop in Biden’s home state of Delaware in April 2019, according to the store’s owner.

Other material extracted from the computer includes a raunchy, 12-minute video that appears to show Hunter, who’s admitted struggling with addiction problems, smoking crack while engaged in a sex act with an unidentified woman, as well as numerous other sexually explicit images.
