Treasury Secretary Steven T. Mnuchin said Thursday that the United States is preparing more sanctions against Turkey if American pastor Andrew Brunson is not released from custody. “We have more that we’re planning to do if they don’t release him quickly,” he said. Mr. Mnuchin gave the update at a Cabinet meeting, where President Trump said Turkey is not turning out to be a great friend of the U.S. Mr. Trump said of the pastor, “He’s a very innocent man.” The administration sanctioned two top Turkish officials last week over the imprisonment of Mr. Brunson, who was released from jail last month but is still being detained on house arrest. Turkey has accused him of fomenting an attempted coup, but the U.S. says the charges are phony. Turkey is also seeking the extradition from the U.S. of a Muslim cleric whom it accuses of inciting the coup attempt.
