A group of FBI agents who assisted in criminal investigations stemming from the Jan. 6 assault on the U.S. Capitol filed suit Tuesday in an effort to block the Justice Department from assembling lists of agents for potential disciplinary actions or firings.

Two groups of FBI agents have filed suits against the DOJ, which oversees the bureau, to prevent it from gathering information on the agents and employees within the FBI who investigated President Donald Trump and defendants charged in the January 6 Capitol riot. The agents' concern is that this information will be used to intimidate and fire them.

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.
