Judges in at least seven US states have now reported the unexplained deliveries to their homes and the homes of their family members, The Washington Post reports.

Judge J. Michelle Childs, president of the Federal Judges Association, said she was first targeted shortly after ruling against the Trump administration and had since been targeted six more times.

She said: “It’s unsettling because I’d like to go to work every day, even with the hardest case, just feeling like there’s no sense of intimidation.

“It’s really an unnecessary and an unfortunate threat to our security when we’re trying to be judicial officers in a very neutral position with respect to our cases.

“You need a strong judiciary for the system to work. This is infringing on democracy generally.”

Judge Esther Salas, whose son was shot dead at her home in 2020 by a disgruntled lawyer, said she had been told that some of the pizzas had been ordered in her late son’s name.

“It went from judges getting pizzas, to then judges’ children getting pizzas, to then judges getting pizzas or their children getting pizzas that they didn’t order in my murdered son’s name,” she said.

The US Marshals Service said it is “looking into all the unsolicited pizza deliveries to federal judges and taking appropriate steps to address the matter”.
