The New York Times published more than a dozen opinion articles and letters to the editor by Kaveh Afrasiabi. A 2018 Times op-ed under his byline identified him as “a former adviser to Iran’s nuclear negotiation team.” A 2012 Times op-ed identified him as “a former political science professor at Tehran University and former adviser to Iran’s nuclear negotiation team.”
This week, Afrasiabi was arrested and charged with acting as an unregistered foreign agent of the Iranian government.
A press release from the Department of Justice announcing the unsealing of a criminal complaint in the case says, “Since at least 2007 to the present, Afrasiabi has also been secretly employed by the Iranian government and paid by Iranian diplomats assigned to the Permanent Mission of the Islamic Republic of Iran to the United Nations in New York City (IMUN). Afrasiabi has been paid approximately $265,000 in checks drawn on the IMUN’s official bank accounts since 2007 and has received health insurance through the IMUN’s employee health benefit plans since at least 2011.”
The press release said that while employed by the Iranian UN mission, Afrasiabi “authored articles and opinion pieces espousing the Iranian government’s position.”
