DENVER -- Several Colorado politicians are fighting the idea of bringing inmates from the Guantanamo detention camp to Supermax in Colorado.

On Wednesday, Sen. Dianne Feinstein suggested Supermax would be a candidate for housing the Gitmo detainees. She claimed the facility "isn't in a neighborhood. It isn't in a community." Colorado Congressman Doug Lamborn disagrees.

"I resent the fact that Sen. Feinstein would be so dismissive of the nearly 20,000 people who live in Florence and nearby Canon City, Colo., where the great majority of the Supermax correctional officers live. Many of those families live well within a mile of the perimeter of the prison complex. I can assure Mrs. Feinstein that my constituents near the Florence prison do, in fact, live in neighborhoods and communities, and are of equal value to her constituents in California," said Lamborn in a statement to 7NEWS.

Lamborn also said "Supermax is at capacity. To make room for Gitmo detainees, domestic high-risk inmates would have to be transferred to lower level facilities around the country."

State Rep. Buffy McFadyen agreed with Lamborn. She told 7NEWS, "There's literally no room at the inn. We are severely understaffed. Can we handle these prisoners? Yes, with the proper funding, but I'm not convinced the funding will ever come."

McFadyen also said there's "no hardened perimeter around Supermax. We have no walls. I'm not worried about people getting out, they'll never get out. I'm worried about people getting in."

President Barack Obama forcefully defended his plans to close the Guantanamo detention camp Thursday and said some of the terror suspects held there would be brought to top-security prisons in the United States despite fierce opposition in Congress.

He spoke one day after the Senate voted resoundingly to deny him money to close the prison, and he decried "fear-mongering" that he said had led to such opposition.

The president insisted the transfer would not endanger Americans and promised to work with lawmakers to develop a system for holding detainees who can't be tried and can't be turned loose from the Navy-run prison in Cuba.

"There are no neat or easy answers here," Obama said in a speech in which he pledged anew to clean up what he said was "quite simply a mess" at Guantanamo that he had inherited from the Bush administration.

Obama conceded that some Guantanamo detainees would end up in U.S. prisons and said those facilities were tough enough to house even the most dangerous inmates.

Obama decried arguments used against his plans.

"We will be ill-served by the fear-mongering that emerges whenever we discuss this issue," he declared.

Obama said his administration was in the process of studying each of the remaining Guantanamo detainees "to determine the appropriate policies for dealing with them."

"Nobody has ever escaped from one of our 'supermax' prisons, which hold hundreds of convicted terrorists," Obama said.
