I don’t beleive an impeachment would be required. An impeachment and trial is required to remove a President. If Obama is Constitutionally disqualified from the office, he IS NOT President ab initio.
He needs only be escorted out by the US Marshalls, or Secret Service, acting under Court Order.
I suppose my view could be disputed, but this is how I see it.
>He needs only be escorted out by the US Marshalls, or Secret Service, acting under Court Order.<
correct the Marshalls enforce the court order.
the military would be directed by the court not to obey his orders as he is no longer the CIC.
