Are you telling me that if Obama or any other POTUSA were involved in a felony crime and convicted of such a crime he could not be taken to jail before an impeachment process was underway. I Don’t need a lesson on the power of politics or position as I’ve lived through many years of crooked government officials. My query is as to fundamental law.
Obama could not be prosecuted for the felony crime in the courts in the first place.
The most they could do would be to name him an unindicted co-conspirator and go ahead and convict the other people who participated in the felony.
It would be up to the House to indict him (that's what impeachment is) and the Senate to convict and remove him.
Once the Senate has removed him from office, then we can go back to the court proceedings and formally indict him and convict him before a judge and jury for that felony.
