Iran Responds to US Sanctions on Foreign Minister Steve Herman WHITE HOUSE - Iranian President Hassan Rouhani on Thursday called the move by the United States to sanction Iran's foreign minister "childish." In a televised speech, Rouhani said the United States claims to want to negotiate with Iran without any preconditions, "and then they sanction the foreign minister." "This is obviously a highly unusual action," a senior Trump administration official acknowledged when discussing the U.S. action against Foreign Minister Mohammad Javad Zarif. The executive order accuses Zarif of acting or purporting to act on behalf of his country's supreme leader, Ayatollah Ali Khamenei, who was recently added to the U.S. Treasury Department's Specially Designated Nationals and Blocked Persons List. "And today, President [Donald] Trump decided enough is enough," a senior U.S. official told reporters on a background briefing conference call. "We will continue to build on our maximum pressure campaign until Iran abandons its reckless foreign policy that threatens the United States and our allies." The United States "is sending a clear message to the Iranian regime that its recent behavior is completely unacceptable," Treasury Secretary Steven Mnuchin said in a statement. "At the same time, the Iranian regime denies Iranian citizens' access to social media, Foreign Minister Javad Zarif spreads the regime's propaganda and disinformation around the world through these mediums." In a statement, Secretary of State Mike Pompeo said the action is "another step toward denying the Iranian regime the resources to enable terror and oppress the Iranian people." .
