<h1>Congressional oversight rights challenged as access to immigration detention sites is blocked, seeking restoration of unannounced inspections.</h1> Members of Congress filed suit alleging DHS and ICE policies unlawfully obstruct Congressional access to immigration detention facilities and field offices by imposing a seven day notice requirement and barring entry, thereby preventing unannounced inspections of sites where people are held. They contend these restrictions hinder oversight of conditions and the use of detention appropriations, point to denials of entry at multiple locations, and seek immediate judicial relief to restore members' statutory inspection rights.
