A Kent State University professor started an argument with a former U.S. diplomat on campus Tuesday before storming out and shouting "Death to Israel," the Daily Kent Stater reported.

Julio Pino attended a speech given on campus Tuesday night by Ishmael Khaldi, Former Deputy Consul General at the Israeli Consulate in San Francisco and sparked an argument when he asked Khaldi why Israel was contributing to the deaths of Palestinian women and babies, the Stater reported.

Pino, 50, is a tenured history professor and specializes in Latin American history. It's not the first time he's drawn negative attention to himself.

In 2007, he was accused of contributing articles to an anti-American website that claimed to support global terrorism. In 2002, he wrote an opinion piece for the Stater in which he praised a suicide bomber.

In 2009, the Secret Service served a search warrant on his Kent home for what authorities said at the time was an on-going investigation of Pino.
