A federal judge in Texas declared a mistrial Tuesday after a defense lawyer wore a shirt showing civil rights leaders in court. The shirt featured images of Martin Luther King Jr, Shirley Chisholm, and protest scenes. US District Judge Mark Pittman, appointed by Donald Trump, stopped the trial hours after jury selection began in Fort Worth. The lawyer, MarQuetta Clayton, was questioning jurors when the judge criticized the shirt for sending a political message that could bias the jury. Pittman said the shirt risked equating the defendants’ actions with the civil rights movement and suggested the choice to wear it might be deliberate. He added defense lawyers would be upset if prosecutors wore pro-ICE or pro-Trump shirts. The mistrial means the trial will start over with a new jury panel on Monday at 9 a.m. Pittman said, “I don’t think I have any choice but to declare a mistrial.” He also criticized Clayton for showing an unapproved poster to jurors. Clayton is running for county judge in Texas but declined to comment outside court. The nine defendants are charged with terrorism after a July 4 protest at an ICE detention center near Fort Worth. Protesters set off fireworks and some allegedly vandalized property and injured a police officer. Prosecutors say the group wore black clothes and were armed in a coordinated attack. This is the first time the government has charged antifa with terrorism. Defense lawyers disagreed with the mistrial, doubting jurors saw the shirt or were biased. Lead prosecutor Shawn Smith said he never saw a similar case. Some dismissed jurors said the shirt’s imagery would not affect their judgment. Supporters gathered outside were critical of the decision. Before the mistrial, both sides questioned jurors on bias and views on protests. Pittman had previously fined defense lawyers for aggressive legal moves and barred one attorney for residency issues. After the mistrial, Pittman spoke against political division, saying, “we have to find a way to turn down the anger.”
