FBI agents who worked on the Jan. 6 probe are suing the government over plans to review the FBI workforce and agents who may have worked on the investigations.

The FBI agents said in the lawsuit that any effort to review or discriminate agains employees involved in the Jan. 6 investigations would be “unlawful and retaliatory," and a violation of civil service protections.

The agents claim a survey about their roles in any Capitol riot investigations is meant to identify targets to be fired "as a form of politically motivated retribution."
