Elon Musk’s Twitter was fined $350,000 for refusing to comply with a search warrant on Donald Trump’s Twitter account earlier this year, according to new court documents released Wednesday. The warrant was issued as part of the Justice Department’s special investigation.

In January, special counsel Jack Smith obtained a search warrant for former President Trump’s Twitter account, @realdonaldtrump, as part of his investigation into Trump’s role in interfering with the peaceful transfer of power after the 2020 presidential election.

Documents released Tuesday say Twitter, which is now known as X, objected to producing the information demanded in the warrant in February, arguing that its accompanying nondisclosure order was invalid under the First Amendment.

X did not immediately respond to a request for comment.
