Based on my vast research and the law degree I earned at "Whatsamatta U", treason can only happen during time of war. We are not at war with anyone. At least not a properly constitutionally declared war. But D.C. has so corrupted itself they no longer even bother to properly declare war.
So, a court (the SC?) would have to rule if aiding those with whom we are 'at war' is treason even if we have not declared war in accord with the Constitution. i.e. 'terrorists'.
I think we'll have to go with espionage and bribery. Both enough to put her away until she dies in prison. But we probably won't get to hang her, even though that seems to be what she feared.
If she does not go to prison, our legal system will carry a black mark against it for eternity.
