Title 18 › Part I— CRIMES › Chapter 113B— TERRORISM › § 2339B
Makes it a crime to knowingly give help or resources to a foreign terrorist group that the government has officially listed. A person who does this can be fined or jailed for up to 20 years, or both. If someone dies because of the help, the person can be jailed for any term of years or for life. Banks and other financial firms must hold and report any funds they find that belong to a listed terrorist group or its agents, unless the Treasury Secretary allows otherwise. A bank that knowingly ignores this rule can be fined the greater of $50,000 per violation or twice the amount it should have held. The Attorney General can sue in federal court to stop suspected violations, and the United States has jurisdiction in many situations, including for U.S. citizens, lawful permanent residents, people habitually living in the U.S., conduct that happens in or affects the U.S., or when a person is brought into the U.S. after the conduct. The Attorney General leads investigations and works with the Treasury on bank-related matters. The law lets the government protect classified information in civil cases by redacting documents, using summaries, or agreeing to facts instead of showing secrets; courts can speed up appeals about those protections. One-line definitions: classified information — secret government information under the Classified Information Procedures Act; financial institution — banks and similar entities as defined in federal law; funds — money and financial instruments, including electronic forms; material support or resources — the kinds of help listed in the related law (for example, training or expert help); Secretary — the Secretary of the Treasury; terrorist organization — a group officially designated under the Immigration and Nationality Act. A person cannot be charged for providing “personnel” unless they knowingly gave one or more people to work under the group’s direction or to run it; people who act alone and not under the group’s control are not “personnel.” The law does not limit First Amendment rights. If the Secretary of State, with the Attorney General’s agreement, approves giving personnel, training, or expert help to a listed group, the provider cannot be prosecuted, but the Secretary of State may not approve any help that could be used to carry out terrorist acts.
