Habeas corpus in the United States is used to tap into the federal court system to determine if the state's detention of a prisoner is legal. On Friday, a top White House adviser announced that the Trump administration is looking into suspending that writ for migrants,

A writ of habeas corpus requires authorities to produce in court an individual they are holding and justify their confinement. Article I of the Constitution says the "privilege of the writ of habeas corpus shall not be suspended, unless when in cases of rebellion or invasion the public safety may require it."

White House deputy chief of staff Stephen Miller says President Donald Trump is looking for ways to expand its legal power to deport migrants who are in the United States illegally. To achieve that, he says the administration is “actively looking at” suspending habeas corpus,
