June 11 (Bloomberg) -- Democrats plan to allow President Barack Obama to transfer detainees imprisoned at Guantanamo Bay, Cuba, to U.S. shores for trial, lawmakers said, backing away from efforts to bar such proceedings.

Senate Appropriations Committee Chairman Daniel Inouye, a Hawaii Democrat, said he expects his colleagues to formally agree later today to a compromise war-spending bill that would authorize bringing the suspected terrorists to the U.S. for trial. If convicted, though, the detainees couldn’t be imprisoned in the U.S. under the compromise.

“That, I suppose, is what will be agreed to,” said Inouye.

Representative Jack Murtha, a Pennsylvania Democrat who heads the House’s defense spending subcommittee, said Obama has agreed to the plan. The proposal also would require the White House to submit details of its closure plans for the Guantanamo facility before transferring detainees to the U.S. One detainee, a Tanzanian national, has been brought to the U.S. for trial.

Obama announced shortly after taking office in January that he would close the prison by early next year. The White House has yet to work out plans for relocating the approximately 200 detainees being held at Guantanamo.

House and Senate negotiators plan to meet later today to adopt a compromise on the bill that is mainly designed to continue funding the wars in Iraq and Afghanistan. The measure then may be put to a floor votes in each chamber next week.

The Guantanamo issue helped stall final action after the House and Senate adopted differing drafts of the bill last month. The Senate’s version would bar the administration from transferring suspected terrorists to the U.S.

The move came after weeks of complaints from Republicans that Obama did not have a plan for closing the prison and that transferring detainees onto American soil could endanger public safety.

Since then, Senator Dick Durbin of Illinois, the chamber’s No. 2 Democrat, said his colleagues have had second thoughts about the restrictions because they could make it harder for the administration to proceed with closing the facility.
