@oralloy,
And if Trump and Barr don't appoint anyone, then what?
And you keep saying the Biden Administration, even though Biden and his cabinet are not even in office yet.
So how is Trump supposed to appoint an independent prosecutor against an administration who hasn't even done anything yet? Is this prosecutor supposed to make sure the new admin follows the law, or to investigate Biden on his past actions during the Obama Administration?
If the latter, then why hasn't Trump ordered an investigation during his last 4 years? He promised an investigation for Hillary Clinton but he never had one.
