The report said Soyinka, a scholar-in-residence at New York University’s Institute of American Affairs, disclosed the plan in a speech to Oxford students.

His comments come less than three weeks after 70 Nobel laureates backed Democratic Presidential candidate Hillary Clinton.

Regardless, Clinton has seen her lead in poll slip after the FBI announced that it was reopening her email probe.
