Quote:Bobulinski said that, in 2017, Hunter Biden consulted with his father about forming a new venture with CEFC China Energy Co. to invest in real estate and technology in the U.S. Bobulinski was brought into the venture by James Gilliar, an English businessman who purportedly knew the Bidens through Rob Walker, a former Clinton administration official. 

Bobulinski became a partner and CEO of the venture, which was named SinoHawk Holdings LLC. The company was incorporated in Delaware in May 2017.

So how is it Bobulinski was partner and CEO, but Hunter needs to be investigated for money laundering?
That doesn't even pass the common sense rule.
