The optics are clear, the Bidens took bribes from the Communists in China, and that is wrong if not illegal. One need not be a genius to figure this out. So where does the truth come from? There is no harm asking China what gives?
We already know that Biden has been bought by China. His comment that China is not a competitor of the USA is reflective of that very fact. Biden is owned by China. When the American people think through this, they will not want Biden as dog catcher. This self serving nonsense is exactly what every key person in the Obama Administration was doing. Clinton with her $145 million bribe from Russia.
Trump asking for an investigation is perfectly within his right as POTUS. Trump's failure was not doing this with every Dem, particularly Hillary and Bill Clinton.
