WASHINGTON (CN) - Recidivism is a smaller problem for Guantanamo detainees now than under the previous administration, but Republicans insisted on Capitol Hill today that the prison camp must stay open for this reason.
Preaching at a hearing this afternoon of the House Foreign Affairs Committee, Rep. Ed Royce, a California Republican who chairs this group, said more than 30 percent of detainees released from Guantanamo Bay, so far, actually returned, or are suspected to have returned, to the battlefield.
Lee Wolosky, the State Department's special envoy on Guantanamo closure, meanwhile told the committee that new processes put in place by the Obama administration have brought those numbers down markedly.
A report this month from the Office of the Director of National Intelligence puts the confirmed recidivism rate at just under 5 percent - with seven of 144 detainees released by the Obama administration confirmed of re-engaging, and 12 more suspected.
Those numbers were much higher for the 532 detainees released by the Bush administration - about 21 percent actually reengaged, while about 14 percent were suspected of reengaging, according to the same report.
Both Wolosky and his counterpart at the Defense Department, Paul Lewis, highlighted for lawmakers that Guantanamo serves as a potent propaganda tool for extremist recruitment, while also draining resources and damaging U.S. relations with key allies.
Democrats rallied around the message.
"The only justification for keeping the prison open is fear," Rep. Eliot Engel, D-N.Y., said. "Fear of violent extremism. Fear that our justice system or prison system cannot get the job done, despite all the evidence to the contrary. And fear is precisely what our enemies want to instill in us. And I don't want them to win."
House Republicans would not be swayed, however, even as the dust settles in Brussels after a terrorist attack there by the Islamic State on Tuesday killed 31 and injuring 270.
"ISIS is continuing to threaten and expand in Libya, Afghanistan and elsewhere," Royce continued. "Europe is under siege by jihadists. We are under attack. So unfortunately, we are going to need a detention facility for fanatical terrorists whose processing in the U.S. legal system is unwarranted and simply not feasible. We're going to need that for some time to come."
Wolosky and Lewis tried to assure the committee about the process by which the Obama administration assesses the risk of every Guantanamo detainee.
Each determination requires unanimity, Wolosky said, from the Justice Department, Defense Department, State Department, Homeland Security, Joint Chiefs of Staff and the Office of the Director of National Intelligence after thorough reviews of a detainee's record.
Outcomes for the detainees include keeping them under indefinite detention, referring them for prosecution or transferring those approved for release.
With detainees eligible for full review by the Periodic Review Board every three years, Wolosky said the board has approved 16 detainees for transfer after 29 hearings.
Of the 91 remaining Guantanamo detainees, he added, 36 have been approved for transfer, 10 are being processed in the military commissions system and 45 are designated for ongoing detention.
Though Royce questioned how well transfer countries can properly monitor and surveil released detainees, Wolosky and Lewis both said the process of determining a country's capability is rigorous.
