The US will find a way to cope securely with dangerous detainees at Guantanamo Bay, President Barack Obama has said.
He described Guantanamo as a "misguided experiment", but conceded some of those held still posed a threat to the US.
Some could be jailed in mainland US prisons, Mr Obama suggested, under a new legal framework for detainees that would see the camp close by early 2010.
Congress has rejected Mr Obama's move to fund the closure of Guantanamo, amid concern over moving inmates to the US.
Speaking afterwards, former Vice-President Dick Cheney strongly defended Bush-era security strategies.
He recalled the experience of being in a White House bunker during the 9/11 attacks and said this shaped the way he viewed his responsibilities.
And he defended the "enhanced interrogation" authorised by the Bush administration to extract information from terror suspects as "legal, essential, justified and successful".
