The Fourth Amendment to the Constitution
The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.
It would be absurd for an administration that says Scalia is their model for Supreme Court Justices to not adopt a plain reading of the document so if the administration authorized warrantless searches and seizures of homes, one can only conclude that the administration believes the Constitution is irrelevant.
For those with even the most minimal understanding of history, the Fourth Amendment was specifically created to protect citizens after abuses by the British government and military which ignored protections under British law—hence why Edmund Burke supported the American War of Independence, he saw it as a fight by Englishmen to protect their rights as Englishmen.
To suggest an authorization of force or even declaration of war would negate the Fourth Amendment is absurd. To act on such a claim is the essence of a high crime.
