“Very powerful grounds” will be used by Trump to ask the judge in his alleged election fraud case to step aside.

According to him, he cannot have a fair trial without a different judge.

He called after the prosecution requested a court order restricting his public statements about the case.

Former President Barack Obama appointed Tanya Chutkan as the judge.

On Sunday morning, Trump took to his social media platform, Truth Social, to call the case “the ridiculous freedom of speech/fair elections case” and said his legal team would immediately request the judge’s recusal.

Her resignation was not accompanied by any details as to the reasons for his request.

Previously, Chutkan ruled against Mr Trump’s attempts to shield evidence from the House January 6 Committee.

As a result of his harsh sentences for those convicted of participating in the riots, the 61-year-old judge has earned a reputation as a harsh judge. It is said that she is one of the toughest punishers in the world, according to the Associated Press.

A US federal judge must disqualify himself or herself from any proceeding in which their impartiality might reasonably be questioned.

The recusal of the judge was not the only request Mr Trump made. Also, he asked for a “venue change” and for his case to be moved outside of Washington.

A fair trial is impossible in Washington, which he describes as “anti-Trump”, and he has previously described the Department of Justice as “highly partisan and very corrupt”.

According to John Lauro, Mr Trump’s lawyer, the former president “believed in his heart of hearts” that he had won the 2020 election – and that prosecutors will not be able to prove otherwise.

During an interview with US TV networks, Mr Lauro said Mr Trump was being attacked for exercising his constitutional First Amendment right to freedom of speech.

On Truth Social, Mr Trump wrote, “If you go after me, I’m coming after you!” just one day after pleading not guilty to four charges in the alleged election fraud case.

Prosecutors also requested a protective order to prevent “the improper dissemination or use of discovery materials, including to the public”, because they feared Mr Trump might reveal confidential evidence.

Mr Trump’s legal team has until 17:00 local time on Monday to respond to Chutkan’s submission. Lawyers for Mr Trump requested three more days, but the judge denied their request.
