A historian and former Sandinista leader who helped overthrow Nicaraguan dictator Anastasio Somoza is no longer scheduled to teach classes at Harvard Divinity School this spring after she said she was denied a visa because of her role in alleged "terrorist activity." Since 1998, Tellez has been president of the Sandinista Renewal Movement, a political party allied with the Sandinistas. At Harvard Divinity School, Tellez was scheduled to teach a class on Nicaragua and the Sandinista aftermath, as well as a seminar on Caribbean identity, race, and ethnicity.
