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.

Chicago and other cities like it — notably Denver, New York and Boston, all of which hold sanctuary city status like Chicago — are being investigated by the U.S. House Committee on Oversight and Government Reform.
