Turkey “will not lose the economic war” with the United States, President Recep Tayyip Erdogan said Friday amid escalating tensions with the Trump administration over the fate of an imprisoned American pastor.

“Those who have dollars, euros, or gold under their pillows [savings at home] should go and exchange them with the [Turkish] lira,” Erdogan said, per the Hurriyet Daily News. “This is a national struggle. This will be my nation’s response to those who have declared an economic war.”
