1. PROVIDING MATERIAL SUPPORT TO DESIGNATED TERRORIST ORGANIZATIONS (FUNDRAISING) (18 U.S.C. 2339B)
   The Antiterrorism and Effective Death Penalty Act of 1996 gave the Secretary of State authority to designate foreign terrorist organizations whose terrorist activity threatens the security of United States nationals or the national defense, foreign relations or economic interests of the United States. See Pub. L. 104-132, § 302, 110 Stat. 1214, 1248. See also section 219 of the Immigration and Nationality Act (8 U.S.C. § 1189). The Antiterrorism Act also created 18 U.S.C. § 2339B, which makes it unlawful, within the United States, or for any person who is subject to the jurisdiction of the United States anywhere, to knowingly provide material support to a foreign terrorist organization that has been designated by the Secretary of State. See Pub. L. 104-132, § 303, 110 Stat. 1214, 1250.

Note: The HARM act hasn't passed yet, so this might be on shaky grounds. But he may yet find himself in violation. Also, I'm not a lawyer, and I'd bet there's better ways to prosecute this.

What is FARA?

FARA is an acronym for the Foreign Agents Registration Act of 1938, as amended, 22 U.S.C. § 611 et seq. (“FARA” or “the Act”). FARA requires the registration of, and disclosures by, an “agent of a foreign principal” who, either directly or through another person, within the United States (1) engages in “political activities” on behalf of a foreign principal; (2) acts as a foreign principal’s public relations counsel, publicity agent, information-service employee, or political consultant; (3) solicits, collects, disburses, or dispenses contributions, loans, money, or other things of value for or in the interest of a foreign principal; or (4) represents the interests of the foreign principal before any agency or official of the U.S. government. In addition, FARA requires agents to conspicuously label “informational materials” transmitted in the United States for or in the interest of a foreign principal. There are some exemptions to FARA’s registration and labeling requirements for specified categories of agents and activities.

What are the penalties for violating FARA?

The penalty for a willful violation of FARA is imprisonment for not more than five years, a fine of up to $250,000, or both. Certain violations are considered misdemeanors, with penalties of imprisonment of not more than six months, a fine of not more than $5,000, or both. There are also civil enforcement provisions that empower the Attorney General to seek an injunction requiring registration under FARA (for applicable activities) or correcting a deficient registration statement.
