New York City comptroller Brad Lander, a Democratic candidate for mayor, was accosted and arrested by masked federal ICE agents after an immigration court hearing.

“You don’t have the authority to arrest U.S. citizens,” Lander told the masked agents.

The incident comes days after police handcuffed Sen. Alex Padilla, D-Calif., after he was forcibly removed from a press conference that DHS Secretary Kristi Noem was holding.
