According to Fox News:
The Senate Homeland Security and Governmental Affairs Committee is investigating newly released emails which revealed that Hunter Biden introduced his father, former Vice President Joe Biden, to a top executive at Ukrainian natural gas firm Burisma Holdings in 2015 at Hunter’s request.
Committee Chairman Ron Johnson, R-Wis., told Fox News on Wednesday that the committee has been in touch with the person who provided the emails and was in the process of validating the information.
The emails in question were obtained by The New York Post and revealed that Biden’s son introduced the former vice president to a top executive at Ukrainian natural gas firm Burisma Holdings less than a year before he pressured government officials in Ukraine to fire prosecutor Viktor Shokin who was investigating the company.
“We regularly speak with individuals who email the committee’s whistleblower account to determine whether we can validate their claims,” Johnson told Fox News. “Although we consider those communications to be confidential, because the individual in this instance spoke with the media about his contact with the committee, we can confirm receipt of his email complaint, have been in contact with the whistleblower, and are in the process of validating the information he provided.”
