An associate professor at Kent State University in Ohio is under investigation by the Federal Bureau of Investigation over possible involvement with the Islamic State.

The inquiry came to light as federal agents arrived at the campus this week to interview students and professors about Julio Pino, an educator in the history department known for making incendiary remarks on Israel.

Emily Mills, a journalism student who was questioned on Tuesday, said the agents told her they began scrutinizing Dr. Pino more than a year ago. “They were looking into Professor Pino allegedly having ties to the Islamic State and recruiting students to join on campus,” she said.

Ms. Mills said she was asked about her encounters with Dr. Pino as she reported articles about him for The Kent Stater, a student newspaper where she serves as editor.
