[JURIST] After spending the weekend at Camp Delta at Guantanamo Bay, US Senators Ron Wyden (D-OR) [official website] and Ben Nelson (D-NE) told reporters Monday that while closing the military detention center is not necessary, establishing a precise legal status for prisoners and clarifying the rules governing them is. In a statement [text] posted on his website, Nelson noted that recent changes in management and increased oversight of the facility warrant it remaining open. Earlier this month, US Senate Judiciary Committee Chairman Arlen Specter opened hearings [JURIST report] on the legal rights of detainees. The committee is expected to propose legislation delineating the rights and legal status of terror suspects in US detention. AP has more.
