Do you trust the Feds and have faith they actually intend to investigate and bring actual charges?
No, I have faith that they will do what they always do. What they are told to do by the US Attorney General.
My point, which seems to be difficult for you to understand, is that it is the Democrats that control the Feds at the moment, not Trump. You came running in here talking about their Fuhrer, well that man is not in office yet, and will not be in office until Jan. 2025. You want to lay blame at anyone's feet, if it is not really investigated, then you lay that blame where it belongs. The Democratic Party.
Edit: If you need it to be a President, like you wanted to do originally, then Biden is to blame.
