The federal judge assigned to the case brought by former President Donald Trump against Hillary Clinton and others involved with creating the Trump-Russia dossier should be disqualified, Trump said through his lawyers on April 4.

U.S. District Judge Donald Middlebrooks should not oversee the case because he was appointed in 1997 by then-President Bill Clinton, Trump said in a motion to disqualify the judge.

Bill Clinton has been married to Hillary Clinton, Trump’s rival in the 2016 presidential election, since 1975.
