WASHINGTON (AP) — A day after threatening Turkey with economic ruin if it goes too far in invading northern Syria, President Donald Trump says he’ll host Turkish President Recep Tayyip Erdogan at the White House next month. The announcement came one day after Trump publicly warned Turkey it would be in “big trouble” if any American troops in Syria are injured during a military operation Turkey is preparing to launch against Kurdish fighters allied with the U.S. against Islamic State militants.
