On Monday, Donald Trump appeared to confirm that he is willing—even eager—to declare a national emergency and use the military to carry out his plans for mass deportations. “TRUE!!!” he wrote on social media, responding to a post suggesting that reports were circulating of the president-elect’s preparedness to go to such extreme lengths to implement his cruel immigration policies. Trump’s desire to deport millions of undocumented immigrants can be traced to his first presidency, during which migrant families were deliberately separated and sweeping workplace raids were conducted.
