Pardoned by Trump, Jan. 6 Defendants Assail Those Who Worked on Their Cases

In one post, a rioter pardoned by President Trump after taking part in the storming of the Capitol expressed his “joy and happiness” at just how badly prosecutors who worked on cases like his own were “hurting right now” after some of them were fired.

In a different post, another pardoned rioter taunted agents who worked on investigations linked to the events of Jan. 6, 2021, ridiculing them for worrying that they would be revealed and asking sarcastically, “Why would you be afraid of us knowing your names?”

In a third post, yet another rioter granted clemency by the president featured the image of a document that clearly showed the name and cellphone number of the F.B.I. agent who oversaw his case.

In the past few weeks, an increasing number of Jan. 6 defendants who benefited from Mr. Trump’s mercy have gone on the attack on social media, lashing out at the agents and prosecutors who worked on their criminal cases. The pardoned rioters have assailed these law enforcement officials as “traitors” or “evil,” often doxxing them by posting their names, photos and contact information online.

Many of the messages are likely protected by the First Amendment and, at least for now, there is no indication that they have led to any violence.

But the posts also suggest a mounting and disturbing desire for revenge on the part of the pardoned rioters, and experts have raised concerns that the frequency and number of the digital attacks could increase the risk that violence might eventually occur.
