An anonymous group of FBI employees sued the U.S. Justice Department on Tuesday, seeking to protect the identities of those agents and others who investigated supporters of Donald Trump for storming the U.

Two sets of FBI agents who worked on cases stemming from the Jan. 6 attack on the Capitol — as well as the criminal investigations of President Donald Trump — have filed lawsuits to block Justice Department leadership from assembling lists of agents they say will be used as part of a retaliation campaign.

FBI officials have complied with demands to provide the Justice Department with a list of thousands of employees who worked on investigations related to the January 6, 2021, US Capitol riot, according to people familiar with the situation.
