New York City Comptroller and Democratic mayoral candidate Brad Lander was arrested Tuesday by masked U.S. Immigration and Customs Enforcement agents inside federal immigration court in Lower Manhattan.

"I'm happy to report I'm just fine, I lost a button," Lander said after leaving the courthouse with New York Gov. Kathy Hochul (D). But "the rule of law is not fine and our constitutional democracy is not fine," he added. "We are normalizing family separation" and "due process rights violations."
