"Perhaps not treason, but certainly seditious conspiracy defined in US Code"

1.7 Billion dollars, in cash, flown at night, to an enemy of the United States, without an act of congress.

18 U.S. Code § 2339B

Seems treasonous to me

[Reily]

Treason is specifically defined by the Constitution.

Article III Section III

Treason against the United States, shall consist only in levying war against them, or in adhering to their enemies, giving them aid and comfort. No person shall be convicted of treason unless on the testimony of two witnesses to the same overt act, or on confession in open court.
The Congress shall have power to declare the punishment of treason, but no attainder of treason shall work corruption of blood, or forfeiture except during the life of the person attainted.
