Former U.S. Envoy Morse Tan Charged in South Korea Over U.S. Speech

Morse Tan, a former U.S. ambassador-at-large for global criminal justice during the first Trump administration, was indicted in South Korea on defamation charges for comments he made about President Lee Jae Myung during a 2025 address at the National Press Club in Washington, D.C. South Korean authorities have prevented Tan from leaving the country, asserting that his statements— which referenced alleged misconduct— violate Korean defamation law.

Tan’s legal team contends the remarks are protected by the U.S. Constitution’s First Amendment, creating a diplomatic clash over jurisdiction. The indictment marks a rare instance of a former U.S. diplomat facing criminal prosecution abroad for speech given on American soil. The case highlights tensions between national defamation statutes and international free-speech norms, and observers warn it could set a precedent for how other foreign officials are treated when speaking abroad.
