The Justice Department on Friday asked a federal judge overseeing the criminal case against former President Donald Trump in Washington to step in after he released a post online that appeared to promise revenge on anyone who goes after him.

Prosecutors asked U.S. District Court Judge Tanya Chutkan to issue a protective order in the case a day after Trump pleaded not guilty to charges of trying to overturn his 2020 election loss and block the peaceful transition of power. The order – which is different from a so-called “gag order” – would limit what information Trump and his legal team could share publicly about the case brought by special counsel Jack Smith.

Such protective orders are common in criminal cases, but prosecutors said it’s “particularly important in this case” because Trump has issued public statements on social media regarding witnesses, judges, attorneys, and others associated with legal matters pending against him.”

They pointed specifically to a post on Trump’s Truth Social platform from earlier Friday in which Trump wrote, in all capital letters, “If you go after me, I’m coming after you.”

Prosecutors said they are ready to hand over a “substantial” amount of evidence – “much of which includes sensitive and confidential information” – to Trump’s legal team.

Prosecutors told the judge that if Trump were to begin posting about grand jury transcripts or other evidence provided by the Justice Department, it could have a “harmful chilling effect on witnesses or adversely affect the fair administration of justice in this case.”

Prosecutors’ proposed protective order seeks to prevent Trump and his lawyers from disclosing materials provided by the government to anyone other than people on his legal team, possible witnesses, the witnesses’ lawyers or others approved by the court. It would put stricter limits on “sensitive materials,” which includes grand jury witness testimony and materials obtained through sealed search warrants.

The indictment unsealed last week accuses Trump of brazenly conspiring with allies to spread falsehoods and concoct schemes intended to overturn his election loss to President Joe Biden as his legal challenges floundered in court.

Trump faces charges including conspiracy to defraud the U.S. and conspiracy to obstruct Congress’ certification of President Joe Biden’s electoral victory.

After his court appearance on Thursday, Trump characterized the case as a “persecution” designed to hurt his 2024 presidential campaign, calling it a “very sad day for America.”

It’s the third criminal case brought this year against the early front-runner in the 2024 Republican presidential primary. But it’s the first case to try to hold Trump responsible for his efforts to remain in power during the chaotic weeks between his election loss and the attack by his supporters on the U.S. Capitol on Jan. 6, 2021.

Smith has said prosecutors will seek a “speedy trial” against Trump in the election case and are expected to propose a trial date next week.

Trump is already scheduled to stand trial in March in the New York case stemming from hush-money payments made during the 2016 campaign and in May in the federal case in Florida stemming from classified documents found at his Mar-a-Lago estate.
