Mayor Johnson was asked​ by the House Oversight Committee to testify on Capitol Hill next month about Chicago's sanctuary city status — along with other big city mayors.

Mayor Brandon Johnson says the city will continue to protect civil and human rights, a day after the mayor received a letter from Washington, D.C., stating, in summary, that Chicago and other “sanctuary cities” like it are being investigated by the U.

The mayor’s exchanges with officials show he is more reluctant than predecessors Lori Lightfoot and Rahm Emanuel to put much in writing.
