Suit made against Ice comes as Trump vows to deport millions of undocumented immigrants upon taking office

The American Civil Liberties Union (ACLU) has filed a lawsuit against Immigration and Customs Enforcement (Ice) seeking more information about how the agency might carry out Donald Trump’s plans for a mass deportation program.

The US president-elect has vowed to deport millions of undocumented immigrants upon taking office, a threat that he has doubled down on since winning the presidential race earlier this month. On Monday, Trump confirmed a report that he intended to declare a national emergency to activate military resources as part of the mass deportation operation.
