The House Judiciary Committee asked CBS News on Friday to provide the committee with records related to the network’s recent termination of journalist Catherine Herridge after accusations surfaced that her now-former employer inappropriately seized her belongings when she left.

The committee requested in a letter to CBS News President Ingrid Ciprian-Matthews that she provide lawmakers with a briefing about the events surrounding Herridge’s exit, as well as provide them with certain internal company communications about it by March 1.

Herridge, a journalist of over 25 years, worked at Fox News until 2019 before becoming a senior investigative correspondent at CBS News.

She has gained prominence in recent years for amplifying Republicans’ efforts to investigate the Biden family. However, she began making headlines more recently after a judge signaled he may soon hold her in civil contempt of court for refusing to disclose sources related to reporting she did at Fox News on a scientist’s alleged ties to the Chinese military.

Herridge was among a small batch of employees CBS News laid off this month. Her termination alone was jolting because of her notoriety, but George Washington University law professor Jonathan Turley revealed in an op-ed that the nature of her exit was “unusual” and had raised alarms internally.
