Special counsel Jack Smith on Friday asked a judge to limit the extent former President Trump can discuss his looming trial on charges related to his effort to block the transfer of power in the 2020 election, citing a history of targeting those who “present an obstacle” to him.

The order asks federal district court Judge Tanya Chutkan to restrict “certain prejudicial extrajudicial statements” from Trump about the 2020 election case, seeking a “narrow, well-defined restriction” limiting discussion about the testimony or credibility of witnesses in the case, as well as court personnel and jurors.

The government said the gag order was needed because Trump “has an established practice of issuing inflammatory public statements targeted at individuals or institutions that present an obstacle or challenge to him.”
