Washington, D.C. ? Top officials of the Obama administration met privately Monday to discuss how to close the Guantanamo Bay detention facility.

Attorney General Eric Holder hosted the first Cabinet-level meeting of President Barack Obama’s Guantanamo task force. Participating in the meeting, among others, were Secretary of State Hillary Rodham Clinton, Defense Secretary Robert Gates, CIA Director Leon Panetta and FBI Director Robert Mueller.

Obama has pledged to close the facility for terror suspects within a year, and officials must decide which suspects to ship away to foreign countries and which to bring to trial in U.S. courts, or tried and held by the U.S. in some other fashion.

At Monday’s high-level meeting, the group discussed standards for reviewing detainee cases, which detainee decisions will get priority, and what has been done to date.

According to an official familiar with the process, detainees are being grouped into categories, and government officials from multiple agencies are being grouped into teams assigned to examine particular categories of detainees.
