Ok, I hit pay dirt; treason can be committed —anywhere—.
(Separated text for ease of reading)
Treason:
“Whoever,
owing allegiance to the United States,
levies war against them or adheres to their enemies,
giving them aid and comfort
within the United States or elsewhere,
is guilty of treason and shall suffer death,
or shall be imprisoned not less than five years and fined under this title but not less than $10,000;
and shall be incapable of holding any office under the United States. ...”
Thanks for that - and I remember Q mentioning something about the traitor needs to either admit guilt or there must be 2 witnesses. And Q mentioning something about 2 witnesses, at least one one phone call, good guys listening it, iirc. I’m sure others remember more/better.
