Stephen Miller, President Trump's top policy adviser, said Friday the White House is exploring the option of suspending habeas corpus, the constitutional provision that protects from unlawful detainment.

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."

Senate Majority Whip John Barrasso told NBC's "Meet the Press" on Sunday, on the third time the question was asked, that he doesn't believe Congress will even consider suspending the right to Habeas Corpus,
