Former President Donald Trump attacked special counsel Jack Smith on Sunday night amid reports the Justice Department obtained a search warrant for his Twitter account earlier this year.

How dare lowlife prosecutor, Deranged Jack Smith, break into my former Twitter account without informing me and, indeed, trying to completely hide this atrocity from me, Trump wrote on his Truth Social account. What could he possibly find out that is not already known.

Court documents unsealed Wednesday first revealed that Smith obtained the warrant in January as part of his investigation into Trumps efforts to overturn the 2020 presidential election. Trump was indicted in that probe earlier this month and faces four federal charges related to a multi-pronged conspiracy to stay in power, according to prosecutors allegations.

Trump has pleaded not guilty to all charges, as well as those in another indictment filed by Smiths team linked to his handling of classified documents after he left the White House.

Twitter, now known as X, initially resisted the search warrant, arguing part of it that included a nondisclosure order violated the First Amendment. The district court fined the company $350,000 after it delayed complying, and Twitter later turned over the details of Trumps handle.

Its unclear what prosecutors were looking for in Trumps Twitter account, which has been dormant since he was booted from the platform in 2021. News of the warrant came after a federal appeals court decision rejected Twitters assertions it shouldnt have been held in contempt of court and been fined.

The former president went on to compare the warrant to the search of his Mar-a-Lago club and residence last year, a key moment in Smiths investigation into Trumps handling of classified documents.

CORRECTION: A prior version of this story incorrectly said the Justice Department fined Twitter. It was the district court that did so.
