ISTANBUL, April 24 (Reuters) - Turkish President Tayyip Erdogan will meet his U.S. counterpart, Donald Trump, at the White House in an upcoming visit in mid-May, Turkish Presidential Spokesman Ibrahim Kalin said on Monday.

The invitation came from Trump, Kalin said, adding the two would discuss Syria, Iraq and the potential extradition of the U.S.-based Muslim cleric Fethullah Gulen, whom Ankara accuses of orchestrating a failed coup last year.
