Brad Lander, who is the New York City Comptroller and a Democratic candidate for mayor, was arrested by federal agents at an immigration court. This happened after he joined arms with someone the authorities wanted to arrest. Lander was at the federal building in Manhattan, watching immigration court hearings. When agents tried to arrest a man leaving a courtroom, Lander held onto him and asked to see a court order. The agents eventually pulled them apart and arrested Lander. After he was released, Lander said he was just trying to oppose Trump's immigration policies peacefully. This arrest is happening while there are more large arrests outside immigration courts across the country. Other Democratic candidates and politicians have criticized Lander's arrest.
