What is a requirement of all members of Congress?

The Constitution requires that Members of the House be at least 25 years old, have been a U.S. citizen for at least seven years, and live in the state they represent (though not necessarily the same district).

Explanation:

The Constitution requires that Members of the House be at least 25 years old, have been a U.S. citizen for at least seven years, and live in the state they represent (though not necessarily the same district).

the fourth amendment protects:

"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."  

so this would mean the denial to search and seizure without warrant or permission.
