The Justice Department is being urged to investigate a series of suspicious pizza deliveries to federal judges’ homes — some of which were ordered using the name of a judge’s son who was fatally shot by a fake deliveryman.

Senate Judiciary Committee ranking member Dick Durbin (D-Ill.) urged U.S. Attorney General Pam Bondi and FBI Director Kash Patel on Tuesday to investigate the orders that he said aim to elicit fear by showing the recipients that the sender knows where they live.

“The targeted individuals reportedly include Supreme Court justices, judges handling legal cases involving the Trump Administration, and the children of judges,” said Durbin in a letter. “Some of these deliveries were made using the name of Judge Esther Salas’s son, Daniel Anderl, who was murdered at the family’s home by a former litigant who posed as a deliveryman.”

Salas, whose 20-year-old son and husband were both shot at her front door in 2020, spoke out against the mysterious deliveries last month ― some of which she said she has received ― and the twisted use of her son’s name to harm others.

“My murdered son’s name is now being attached, weaponized, is being used as a weapon against these judicial officers,” she told NJ.com.

“It says, ‘I know where you live. I know where your kids live.’ And, ‘Do you want to end up like Judge Salas? Do you want to end up like her son?’ These are unprecedented attacks on judicial officers,” she said.

Federal judges have increasingly reported death threats, swatting calls and acts of intimidation against themselves and their families while overseeing high-profile cases that challenge Trump administration policies.

President Donald Trump has meanwhile encouraged the backlash against them, with him publicly calling one judge who ruled against him a “Radical Left Lunatic, a troublemaker and agitator” who he said should be impeached.

On Wednesday, Trump accused the court system of inappropriately blocking him from doing “the job I was Elected to do” when it comes to his mass deportation efforts, which a second federal judge on Tuesday ruled against.

“Activist judges must let the Trump Administration deport murderers, and other criminals who have come into our Country illegally, WITHOUT DELAY!!!” he wrote on his Truth Social account.

Durbin asked that the DOJ and FBI respond to his investigation request, as well as questions about the deliveries, by May 20.

Representatives with the DOJ did not immediately respond to HuffPost’s requests for comment Wednesday. The FBI referred HuffPost to the U.S. Marshals Service, which did not immediately respond to a request for comment.
