As everyone knows the Orange Foolius has been charged with unlawful retention of classified documents under 18 USC 793.
But if the government obtains evidence that he transmitted classified documents to a foreign national (remember that NOFORN classification, it means NO FOREIGN NATIONAL), we could be looking at a superseding indictment with a charge under 18 USC 794, unlawful dissemination.
In times of war, breaking this law could be a death penalty case, and the prison sentence is severe under this statute, but at almost 80, it is a given that Trump will either die in prison or while he is awaiting trial, but leaving aside the prison sentence, there is this interesting part of it.
Subsection d) relates to forfeiture, and forfeiture has a long history as a secondary punishment for treason against the state (the crown in English common law) to punish the family members of nobles thinking about deposing the king, where besides being beheaded as the noble’s punishment, that noble’s extended family would be thrown into poverty overnight.
Section B definitely fits the bill, since it was hidden at Mar-a-Lago. (see bolded text)
(d)
(1)Any person convicted of a violation of this section shall forfeit to the United States irrespective of any provision of State law—
(A) any property constituting, or derived from, any proceeds the person obtained, directly or indirectly, as the result of such violation, and
(B) any of the person’s property used, or intended to be used, in any manner or part, to commit, or to facilitate the commission of, such violation.
UPDATE:
They would also seize the plane used to transport the documents to Florida.
