Judge Aileen Cannon pressed special counsel Jack Smith’s team during a hearing Monday about speech restrictions it was seeking to impose on Donald Trump, conveying skepticism that the former president’s words were, as Smith has argued, dangerous.

Cannon, a Trump appointee, had a couple of tense exchanges with one of the prosecutors, David Harbach, after questioning Harbach on what threats exactly Trump’s speech had prompted. Harbach became “snippy” during the questioning, according to CNN reports from the courtroom.
