Top White House aide Stephen Miller says the Trump administration is looking for ways to expand its legal power to deport migrants who are in the United States 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."

The Trump administration is considering whether it can suspend the right of an individual to challenge their detention in court.
