I am not sure, but the FBI are the investigators, and the DOJ are the prosecutors. This needs to go till after January to get this prosecuted...unless there is a pardon.
Not saying this due to your comments, but I am so damned tired of excuses. Again this is not based on your comments.
If they have a case, they should file indictments.
To heck with the Justice Department.
If the FBI has a case against you, do they go to the Justice Department to get sign off? I seriously doubt it.
So just file charges like you would with anyone else who is a crook.
