FACTBOX: Where the candidates stand on Guantanamo

(Reuters) - The U.S. Supreme Court ruled on Thursday that Guantanamo Bay prisoners have the right to go before U.S. federal judges to challenge their detention, a stinging setback for the Bush administration.

Republican John McCain and Democrat Barack Obama, who will contest the November election to succeed President George W. Bush, have pledged to close the military prison in Cuba, which holds terrorism suspects.

Here is a summary of what they have said on the issue.

ARIZONA REPUBLICAN SEN. JOHN MCCAIN

- Has called for closing the facility and moving prisoners to the U.S. military prison at Fort Leavenworth, Kansas.

- In 2006, McCain supported the Military Commissions Act signed into law by President George W. Bush. The legislation provides military trials for some of the detainees and allowed use of evidence obtained through torture.

ILLINOIS DEMOCRATIC SEN. BARACK OBAMA

- Also supports shutting down Guantanamo.

- Says U.S. civilian courts and the traditional military courts-martial system can handle detainee trials.

- Opposed the Military Commissions Act and says he will adhere to the Geneva Conventions, which bans the use of torture of war prisoners.
