Even though nearly a year has passed since the administration's self-imposed deadline to close the Guantánamo Bay military prison, White House press secretary Robert Gibbs said Sunday the facility will not go away any time soon. 

Gibbs admitted that the prison has served as a rallying cause for Islamic terrorists around the world, but he said that a number of legal and legislative roadblocks have prevented the administration from shutting it down by Jan. 2010 as had been originally planned.

"It's certainly not going to close in the next month. I think it's going to be a while before that prison closes," he said during an interview on CNN's "State of the Union."

The Obama administration had spent much of 2009 attempting to find a way to close the military prison that houses 174 detainees, but was unable to find enough support in Congress to open a prison on the U.S. mainland or settle on a location to hold civilian trials for some prisoners.

Gibbs said that President Obama is looking for Republican cooperation to close the prison.

"I think part of this depends on the Republicans' willingness to work with the administration on this," he said.

The press secretary also seemed to acknowledge a report that the Obama administration will issue an executive order to allow some detainees to be held indefinitely without a trial.

"Some would be tried in federal courts, as we've seen done in the past. Some would be tried in military commissions, likely spending the rest of their lives in a maximum security prison that nobody, including terrorists, have ever escaped from," he said. "And some, regrettably, will have to be indefinitely detained. 

"I say regrettably not because it's a bad thing necessarily for them in terms of the fact that they're very dangerous people and we have to make sure that even if we can't prosecute them, we're not putting them back out on the battlefield."
