New York mayoral candidate and city comptroller Brad Lander was detained by ICE agents at a Manhattan courthouse after demanding to see a judicial warrant while assisting an immigrant facing deportation under President Trump’s intensified immigration crackdown.Video shows Lander being handcuffed and restrained as he insisted, “You don’t have the authority to arrest U.S. citizens asking for judicial warrants.” Homeland Security claimed Lander was arrested for assaulting and obstructing federal officers.Lander’s detention has sparked political backlash, with NY Attorney General Letitia James calling it “a shocking abuse of power.” She warned that such actions create fear and weaken public safety.Since Trump’s return to power in January, his administration has lifted restrictions on enforcement at sensitive sites like courthouses and ramped up arrests after immigration court hearings.Nationwide protests against Trump’s immigration policies drew millions over the weekend.Lander, currently polling third in the Democratic primary, had gone to court to support a migrant under threat of deportation. The primary concludes on June 24.
