As President-elect Donald Trump 's mass deportation plan takes shape, the appointment of Tom Homan as "border czar" may be facing significant obstacles.

The president-elect’s team is committed to pursuing immigrants who crossed illegally, but is wary about logistical challenges.

In an interview with CNN’s Victor Blackwell, Chicago Mayor Brandon Johnson vowed to protect the people in his city, when asked whether he would inform US Immigration and Customs Enforcement if there is someone in local police custody who is accused of a serious crime.

Donald Trump’s incoming “border czar” has suggested the president-elect’s plans for mass deportations will begin in Chicago, part of a plan that would deploy law enforcement officers into communities across the country for broad sweeps targeting people living in the country without legal permission.
