Fox News pushes to quash subpoena that could unmask source

WASHINGTON (CN) — The First Amendment cornerstone that allows journalists to keep sources anonymous was put to the test on Tuesday as a federal judge considered a subpoena in a case where a scholar’s ties to China drew an FBI probe.

Yanping Chen, a Chinese American scientist who is founder and head of the the online institution University of Management and Technology, brought the lawsuit five years ago in Washington. She alleges that U.S. law enforcement is responsible for violating her privacy after Fox News reporter Catherine Herridge reported that Chen was under investigation and had once served in the Chinese military.
