The domestic terrorist known as the Olympic Park Bomber says the U.S. government should think twice about transferring Guantanamo Bay detainees to the federal Supermax prison in Colorado, which holds some of America's most notorious criminals.

Eric Robert Rudolph, who is serving a life sentence for a series of bombings that killed two people and wounded scores of others, exclusively told FOX News in a letter dated June 30 that he doubts the Guantanamo detainees will become his fellow inmates at the Supermax prison in Florence, Colo., about 90 miles south of Denver.

"They do not want the detainees' high powered lawyers focusing their ire on Supermax," Rudolph wrote to FOX News. "Washington built a nice little black hole where they throw their unmentionables and they do not want a bunch of New York lawyers shining any light in here."

Among Supermax's notorious inmates are Sept. 11 conspirator Zacarias Moussaoui; "Unabomber" Ted Kaczynski; Oklahoma City bombing conspirator Terry Nichols; 1993 World Trade Center bomber Ramzi Yousef; and Robert Hanssen, a former FBI agent serving life for espionage.

Rudolph, 42, says the prison is already at capacity. "So even if they decide to move the detainees here I do not know where they would put them," Rudolph wrote. "To house that many detainees staff would have to empty one, two, maybe three entire units."

The Supermax prison, dubbed "The Alcatraz of the Rockies," currently holds 465 inmates, 25 short of its capacity, Bureau of Prisons spokeswoman Traci Billingsley told FOXNews.com.

President Obama has called for the Guantanamo prison to be closed by January, and Dean Boyd, a spokesman for the Department of Justice, said no decision has been made regarding where the 229 remaining detainees will be sent once the Cuban facility is shut down.

Boyd said the detainees would "not necessarily" be sent to federal prisons, but he declined to elaborate.

Rudolph said that if the detainees are sent to Colorado, they will receive the same religious privileges at the Supermax prison that they have had at Gitmo.

"The government goes out of its way to please its non-Christian inmates," Rudolph wrote in his letter. "Muslims can buy prayer rugs and Kufi caps. Korans are given away free. A Muslim [Imam] has recently been attached to the chaplain's office."

Detainees at Guantanamo are given 20 minutes of prayer time every day, typically at 5:30 a.m., 1 p.m., 2:30 p.m., 7:30 p.m. and 9:30 p.m., according to Joint Task Force Guantanamo. Each detainee is also issued a personal copy of the Koran, and meal schedules are modified to accommodate holy periods like Ramadan.

Rudolph, who was linked to the racist and anti-Semitic Christian Identity movement before his incarceration, said Jewish and Muslim inmates at Supermax are offered many items not offered to Christian inmates, like "real" whole wheat bread and fresh fruits and vegetables.

"Many of the less than honest inmates 'convert' to Judaism or Islam just to get the Kosher Halal food tray," he wrote. "In contrast, the government's treatment of Christians is different. Christians cannot get the Kosher-Halal food tray."

Billingsley said all federal prisons, including the Supermax facility, accommodate all religious diets.

Rudolph was sentenced to life without parole in July 2005 for setting off a bomb and killing an off-duty police officer and critically wounding a nurse at an abortion clinic in Alabama. He was later sentenced to two additional life terms for the 1996 bombing at the Centennial Olympic Park in Atlanta, which killed a spectator and wounded scores of others, and for other bombings in and around Atlanta.

Rudolph, who bombed several facilities in a campaign against abortion and homosexuality, said his time at Supermax has not changed him.

"I'm still the same person — a little older and little wiser, but still same person, the same convictions," he wrote.

Constructed in 1994 at an estimated cost of $60 million, the Supermax prison, or Administration Maximum (ADX), is one of four facilities located on the 640-acre Florence Federal Correctional Complex in Colorado.

The facility houses the country's most violent, disruptive and escape-prone inmates. No escapes or serious attempts have occurred since its opening, Billingsley said.

Billingsley declined to discuss Rudolph's status at the prison. Inmates considered the most disruptive are allowed up to seven hours of individual recreation opportunities weekly and one 15-minute phone call per month.
