Is this payback to his adopted home state?
Washington (CNN) -- A limited number of detainees from the Guantanamo Bay prison will be transferred to a prison in Illinois, President Obama will announce Tuesday, a senior administration official said.
The exact number is "hard to pin down because categories of detainees may shift. While 100 may be the upper limit, the actual number at well below that (75 or perhaps even less)," said another senior official, who is not authorized to discuss the issue with the media.
About 215 detainees are held by the U.S. military at the camp in Cuba.
An anti-Guantanamo group welcomed the expected announcement from the president.
"We applaud the Obama administration for taking an important step forward toward closing the debacle in Guantanamo Bay," said former Rep. Tom Andrews, who is now director of the National Campaign to Close Guantanamo.
"President Obama is standing with Gen. Colin Powell, who has long called for the closure of Gitmo, and standing up to the politics of fear and manipulation," he said in a statement.
"It's time for Congress to stop playing politics and join the president in removing this stain from America's standing in the world, save American taxpayers millions of dollars and deny al Qaeda one of its most potent recruiting tools."
Illinois Gov. Pat Quinn and Sen. Richard Durbin will go to the White House on Tuesday for a briefing on the plan to use Thomson Correctional Center in Thomson, Illinois, to help shut down the controversial Guantanamo facility.
Illinois state officials have said the plan would call for housing federal prisoners, including some detainees from the Guantanamo Bay prison camp, in the largely vacant maximum-security facility in northern Illinois.
The governor and other officials have said that such a deal could provide up to 2,000 jobs and up to $1 billion in federal money to the area.
Durbin, the Senate's second-ranking Democrat, has spoken positively of the plan. He said in November that federal officials indicated fewer than 100 detainees from Guantanamo would be housed in the 1,600-bed facility. They would be in a wing under the control of the U.S. Defense Department, while the Bureau of Prisons would assume responsibility for the rest of the facility.
Built in 2001, the Thomson prison sat empty for five years because the state lacked the resources to open it. Despite being built as a maximum-security facility, it houses 144 minimum-security male inmates, according to the Illinois Department of Corrections' Web site.
It is about 150 miles west of Chicago.
Among the detainees at Guantanamo are five with alleged ties to the September 11 conspiracy, including accused mastermind Khalid Sheikh Mohammed, who will be transferred to New York to go on trial in civilian court.
