Trump did; it’s a matter of public record. He violated court instructions about blabbing to the media ten times, and was held in contempt by the judge twice.

He repeatedly make false and misleading statements about the trial, the judge, the witnesses, and even the jury on social media and to the press in the entrance hall of the court building itself. The idiot just couldn’t stop himself.

Had he been a regular citizen instead of a former president, he would have almost certainly done jail time just for his behavior during the trial.
