Investigating your son using your position as Vice President of the United States to enter into lucrative dealings with the Chinese Communists ... with your knowledge and blessing ... with the understanding that YOU will receive a goodly portion of the ChiCom's money is "foul play"?! Don't think so, Joe ... THAT stinks to high heaven and rightly deserves to be investigated, vigorously.
You're "not concerned" because you're corrupt, your political friends in the Deep State are corrupt, and your libtard toadies in the lamestream media are corrupt ... and you and all of your corrupt friends will do everything possible to impede a proper investigation and try to cover for you and your son.
Your son, Hunter, is a "grown man" and the "smartest man you know," eh? Hunter is a man-child who has clearly shown himself to be a reckless reprobate. He has demonstrably shown himself to be an out-of-control drug addict and lecher. Hunter abandoned your daughter-in-law and their three children so he could start f*cking your other daughter-in-law (widow of your deceased son) ... and then he abandoned her and impregnated a stripper! He then tried everything possible to deny paternity and refuse financial support for YOUR grandchild. Fortunately, the courts made him face reality.
Joe, your son is a walking, mumbling train wreck and "you're good, as long as he's good," eh? Wow ... the apple did not fall far from the tree in your disastrous family.
