A new whistleblower has come forward to challenge the federal judicial nomination of Emil Bove, sharing evidence with lawmakers suggesting the controversial former attorney for Donald Trump and current top Justice Department official misled lawmakers during his confirmation hearing last month.

The whistleblower — whose existence has not been previously reported — presented documentation that contradicts claims Bove made before the Senate Judiciary Committee about a Justice Department prosecution. The Washington Post reviewed the evidence and agreed to withhold details to protect the identity of the whistleblower, whose lawyers spoke on the condition of anonymity because of the whistleblower’s fear of retribution.

Trump formally nominated Bove in June and a full Senate vote is expected this week — a faster timeline than most other judicial nominations.

The information follows revelations from two other Justice Department whistleblowers who have said that Bove told subordinates in a meeting in March that they may need to ignore court orders that would hamper Trump’s campaign to deport millions of undocumented immigrants. One of those whistleblowers, ousted Justice Department attorney Erez Reuveni, has since gone public with his account.
