(a) the Secretary of the Treasury shall review the assessment mandated by section 1(a) and the report mandated by section 1(b), and, in consultation with the Secretary of State, the Attorney General, and the Secretary of Homeland Security, impose all appropriate sanctions pursuant to section 2(a) of this order and any appropriate sanctions described in section 2(b) of this order; and
I don’t seen any need of trials there. Once they start arresting people then they’ll need trials.
