[JURIST] On Thursday, US President Donald Trump [official website] issued a presidential memorandum [text] delegating many of the President's powers to sanction Iran granted by the Countering America's Adversaries Through Sanctions Act of 2017 [Text] to the Secretary of State, Secretary of the Treasury, and the Secretary of Homeland Security [official websites].
The Secretary of State was delegated the presidential waiver authority under the Act which will allow the Secretary of State to waive requirements to impose or maintain sanctions on individuals. The memo grants Secretary of the Treasury the power to impose sanctions related to Iran's ballistic missile program, Iran's Islamic Revolutionary Guard Corps destabilizing efforts and support of terrorism, human rights abuses, and arms embargo.
The memorandum also delegates the President's responsibilities to submit reports to the appropriate congressional committees regarding individuals who have contributed to Iran's ballistic missile program, United States citizens being detained by Iran or groups supported by Iran, and coordination of sanctions between the United States and the European Union to the Secretary of State.
The delegation comes a day before President Trump is expected to speak [CNN report] regarding his planned approach on Iran and the Iranian nuclear deal.
The authority to sanction certain conduct in Iran delegated by the memorandum was first introduced [JURIST report] by the Senate in March. Later in March, Iran introduced sanctions against 15 US companies for human rights violations in response to US sanctions against countries accused of aiding Iran's ballistic missile program.
