The White House is looking for ways to remove an enemy of Turkish President Recep Erdogan from the U.S. in order to placate Turkey over the murder of journalist Jamal Khashoggi, according to two senior U.S. officials and two other people briefed on the requests.

Trump administration officials last month asked federal law enforcement agencies to examine legal ways of removing exiled Turkish cleric Fethullah Gulen in an attempt to persuade Erdogan to ease pressure on the Saudi government, the four sources said.

The effort includes directives to the Justice Department and FBI that officials reopen Turkey’s case for his extradition, as well as a request to the Homeland Security Department for information about his legal status, the four people said.
