This is what the OP's talking about.
*A former FBI agent who was charged with joining a mob's attack on the U.S. Capitol and cheering on rioters is now working as an adviser to the Justice Department official overseeing its “weaponization working group,” which is examining President Donald Trump's claims of anti-conservative bias inside the department. The former FBI supervisory agent, Jared Lane Wise, is serving as a counselor to Justice Department pardon attorney Ed Martin Jr., who also serves as director of the working group.
*Wise, who worked as a special agent or supervisory special agent for the FBI from 2004 through 2017, was arrested in Oregon on Capitol riot-related misdemeanor charges in May 2023.
Wise repeatedly shouted, “Kill ’em!” as he watched rioters assaulting officers outside the Capitol, according to an FBI agent’s affidavit. Wise clapped his hands and raised his arms ”in triumph” after he entered the building through the Senate wing door, the affidavit says. He left the building about nine minutes after entering.
Police body camera footage showed Wise berating police officers outside the Capitol and repeatedly shouting, “Shame on you!”
“I’m former law enforcement," he told them." You’re disgusting. You are the Nazi. You are the Gestapo. You can’t see it.”
