Donald Trump's deputy chief of staff and DHS security adviser, Stephen Miller, who has been known for his hard-line immigration policies, told reporters at the White House driveway Friday that the administration was looking into stopping a protection that allows detained individuals to challenge their detention in court.

Stephen Miller, a top White House adviser, said the administration is looking for ways to expand its legal power to deport migrants who are in the country illegally.

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."
