Graham is completely correct. As I stated previously, an unlawful enemy combatant (of which there is a specific legal description in the law and the US Supreme Court cases) can be tried by tribunal.
Political criminals like Hillary, podesta, Comey, clapper and all the rest of the deep state dirtbags are not enemy combatants, as much as some folks would like to think they are. They do not meet the legal definition that the courts have set down. So, they will never be deprived of their rights under the Constitution to be tried in the federal courts by a jury of their peers.
This is not just my legal opinion, it is the opinion of almost all lawyers and judges, including Sen Graham who spent 30 years as a military lawyer. The only people who think the law is different are the anonymous boys down at the manure plant who invented the q phenomenon to have a little fun and make a little money at the same time sucking in well meaning gullible people grasping for some sense of justice.
Graham clearly asks if Civilians can be tried by military tribunals under certain circumstances. And the Judge agrees that according precedent that yes they can. That is what I heard.
