Former US President, Donald Trump has said he will ask the judge in his election fraud case to step aside on what he called “very powerful grounds”.

He claimed that “there is no way I can get a fair trial” unless she does.

His call, which gave no details of his grounds for asking her to step down, came after the prosecution requested a court order that would limit what he can publicly say about the case.

The judge, Tanya Chutkan, was appointed by former President Barack Obama.
