I have said in the past I would volunteer to be the Officer-In-Charge of the Firing Party that was detailed to execute John Kerry and Jane Fonda after a conviction for Treason.
Apparently Nancy Reagan is said to be quite happy that Jane Fonda is playing her in "The Butler". With that kind of Republican endorsement, I think Ms Fonda can consider herself 'rehabilitated'.
As for threatening the Secretary of State of the United States, it may not be treason, but it is probably a felony.
