Not sure what you are asking here?

So when you take office are you a citizen?

It would seem yes based on the fact so many are even "dual" citizens.

My fear here is of the slippery slope that I have continued to watch for decades. Through the ongoing war on terror (that seems like it is a war on citizens) laws have been passed over the decades stripping us more of our right to constitutional protections. A trial applied to citizens under such a court would not be due process, nor a trial by ones peers. Not going to go in depth at how the ability to reach guilty verdicts are easier in these courts to be railroaded, but would urge you to look into what happened when Lincoln instituted the same tribunals on citizens.

Seems to me that there are plenty of laws on the books that address the crimes in existing courts, and one would be better off asking why the DOJ is not making arrests and trying them in this manner.
