Chief Justice John G. Roberts Jr. grants a stay that blocks enforcement of an $800 daily contempt fine against Catherine Herridge while the Supreme Court considers her emergency petition.A federal appeals court and Judge Christopher R. Cooper had found Herridge in civil contempt for refusing to identify a federal official she says leaked information about Yanping Chen, who sued under the Privacy Act after FBI scrutiny of alleged ties to the Chinese military.Fox News supports Herridge, she later worked at CBS News, and legal advocates warn the dispute highlights the absence of a federal reporter shield law and the risk that journalists face personal fines for protecting sources.
