Secretary of State Hillary Clinton says she's on board with bringing Khalid Sheikh Mohammed to the city for his trial.

The government intends to try the self-proclaimed mastermind behind the September 11th attacks -- along with 4 other Guantanamo Bay detainees -- in Manhattan federal court.

On NBC's "Meet the Press," Clinton says she understands the trials will be hard for the families of September 11th victims. But she also says a host of agencies weighed in on the decision -- including the Justice and Defense Departments -- and that decision should be respected.

"The most important thing for me is that, you know, they pay the ultimate price for what they did to us on 9/11," Clinton said. "And if the Attorney General and veteran prosecutors think this is the best way to achieve that outcome, then I think they should be given the right to move forward as they see appropriate."

Former mayor Rudy Giuliani says the trials would put New Yorkers at an unnecessary risk.

On CNN's "State of the Union," Giuliani said the better option would be to try them in military court and that the September 11th attacks shouldn't be treated as a civilian act.

"After the attack on the World Trade Center then, after the attacks in Africa, after the attack on the USS Cole, after the attack on the World Trade Center, gosh you'd think that we would learn that we're at war," Giuliani said.

Police Commissioner Ray Kelly said this week his department is already working on a security plan for when the terror suspects arrive.

Meanwhile, federal officials are expected to tour a prison in Illinois on Monday that could be used to house other Guantanamo Bay detainees.

White House officials say the Obama administration may buy the Thomson Correctional Center.

"It's one of the very best super max prisons in the United States of America and federal authorities are interested in looking at it for federal use," said Illinois Governor Pat Quinn.

Officials say the facility will be primarily used as a federal prison, with a portion leased out to house fewer than 100 Guantanamo detainees.

The state-of-the-art prison was built eight years ago and has been virtually vacant due to lack of funding.

Quinn said the purchase will be good for the economy and could generate more than 3,000 jobs.
