Recep Tayyip Erdogan arrived in Washington, Tuesday, November 12, a day before his meeting with U.S. President Donald Trump, who has openly complimented the Turkish leader and his combative ruling style, calling him "a friend" and "hell of a leader."
Erdogan is looking to Trump to lift an embargo on the purchase of America's latest fighter jet.
Trump imposed the freeze after Ankara procured S-400 missiles from Russia.
Washington claims the Russian missiles radar system threatens to compromise NATO defense systems, in particular the F-35 jet's stealth technology.
Washington is alarmed at Ankara's deepening ties with Moscow, but analysts question Trump's room to maneuver with Congress pressuring for sanctions on Turkey.
