END CELLS in CELLS Act

This bill prohibits providing, facilitating, or possessing wireless devices (like cell phones) in U.S. detention facilities (e.g., prisons, jails) if such actions violate existing federal or state laws. It imposes civil fines up to $50,000 per violation (capped at $1 million total) or criminal fines up to $50,000 for intentional violations. The law explicitly excludes lawful law enforcement activities and state enforcement powers, and defines "detention facility" broadly to include all correctional and penal institutions. It applies to conduct occurring after enactment.
