Trump slams Biden over reports Hunter Biden introduced Burisma exec to VP dad: 'Totally corrupt'

President Trump slammed Democratic rival Joe Biden as a "totally corrupt politician" after a New York Post story published on Wednesday alleged a direct link between Hunter Biden's business dealings in Ukraine and his father, then the vice president.

"The whole thing is insane. Joe Biden is a corrupt politician. I've been saying it for a long time," Trump told FOX Business' Stuart Varney during an interview on Thursday.

Newly uncovered emails obtained by New York Post suggest that Hunter Biden introduced his father to a top executive at Ukrainian natural gas firm Burisma Holdings in 2015 one year before his father allegedly pressured the country's government to fire a prosecutor who had launched an investigation into the company.

The main email obtained by the Post is an April 2015 message that the newspaper said was sent to Hunter Biden by Vadym Pozharskyi, an adviser to Burisma's board.

“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 email reads.

Fox News could not independently verify the legitimacy of the emails.
