The office of the New York judge overseeing Donald Trump’s civil fraud trial has been bombarded with death threats and antisemitic abuse following the former president’s online attacks.

Judge Arthur Engoron and his clerk, Allison Greenfield, are said to have received hundreds of threatening, harassing and disparaging messages via telephone and social media.

Attorneys for the New York state court system made the case for the imposition of gag orders on Trump, citing “serious and credible” threats against Engoron and Greenfield.

Transcribed voicemail messages, disclosed in court filings, revealed the extent of the abuse directed at the pair. Alongside racist and sexist attacks the messages contain several death threats. “I mean, honestly, you should be assassinated,” said one. “You should be killed. You should be not assassin executed [sic]. You should be executed.”
