Executive Order 13876, signed by President Donald J. Trump on June 24, 2019, imposes sanctions on Iran's Supreme Leader Ayatollah Ali Khamenei and his office by blocking their property and interests in property within U.S. jurisdiction. It authorizes the Secretary of the Treasury, in consultation with the Secretary of State, to impose sanctions on any person determined to have materially assisted, sponsored, or provided financial, material, or technological support for, or goods or services to or in support of, the Supreme Leader or his office. The order targets senior Iranian officials for advancing the regime's destabilizing objectives, including human rights abuses and support for terrorism. It was implemented by the Treasury Department's Office of Foreign Assets Control (OFAC), which designated eight senior officials, including Ali Shamkhani (Secretary of Iran's Supreme National Security Council), Mohammad Reza Ashtiani (Deputy Chief of Staff of the Iranian Armed Forces), and Gholamreza Soleimani (head of the Basij militia of the IRGC).
