New York City Comptroller Brad Lander, who is also running for mayor as a Democrat, was arrested by federal agents at an immigration court. He was arrested because he linked arms with a person the authorities wanted to arrest. Lander was at the federal building in Manhattan, observing immigration court hearings. When agents tried to arrest a man leaving a courtroom, Lander held onto him and asked to see a judge's warrant. The agents eventually separated them and arrested Lander. After he was released, Lander stated he was simply trying to protest Trump's immigration policies in a peaceful way. This arrest happened during a national increase in arrests outside immigration courtrooms. Other Democratic candidates and politicians have criticized Lander's arrest.
