The chief accountant at Ukraine’s Burisma Energy, who offered to provide US authorities with damning evidence regarding financial crimes involving Joe and Hunter Biden, has been found dead before she could testify.
The Burisma whistleblower, who has been identified as the wife of the former Burisma owner Mykola Lisin, who also died in suspicious circumstances during the years of the Obama administration when vice president Joe Biden and his son Hunter were active in Ukraine.
Giuliani discussed the fate of the now-deceased whistleblower during an interview on Newsmax’s “Saturday Report” with Rita Cosby.
