A federal judge held a veteran investigative reporter in contempt of court on Thursday for not revealing her sources for articles she wrote about a scientist who was investigated by the F.B.I.
The journalist, Catherine Herridge, formerly of CBS News and Fox News, was ordered to pay $800 a day until she divulged the information. The judge, Christopher Cooper of U.S. District Court in Washington, stayed the fine for 30 days to give Ms. Herridge time to appeal.
The case, which has alarmed First Amendment advocates, relates to a series of articles that were written by Ms. Herridge and her colleagues in 2017, while she worked at Fox News. The articles revealed that the F.B.I. had investigated the scientist, Dr. Yanping Chen, a Chinese American who is the president of the University of Management and Technology in Arlington, Va., over suspicions of Chinese military ties and whether she had lied on U.S. immigration forms.
The F.B.I. ended its investigation without bringing charges against Dr. Chen, a year before Ms. Herridge and her colleagues published and aired their reporting.
In 2018, Dr. Chen sued the F.B.I. and other government agencies, accusing them of violating the Privacy Act by leaking information to Ms. Herridge. The Privacy Act has protections for personal information collected by federal agencies.
Judge Cooper ruled last year that Ms. Herridge must reveal her confidential sources. On Thursday, he held her in civil contempt for disobeying that order. He said he had not issued the order lightly, deciding that Dr. Chen’s need for the information overcame Ms. Herridge’s First Amendment protections.
