WASHINGTON — A U.S. military judge at Guantanamo Bay, Cuba, has scheduled hearings in early January for alleged 9/11 mastermind Khalid Sheikh Mohammed and two co-defendants to enter guilty pleas in exchange for life sentences despite Defense Secretary Lloyd Austin’s effort to scuttle the plea agreements.

The move Wednesday by Judge Matthew McCall, an Air Force colonel, in the government’s long-running prosecution in the Sept. 11, 2001, attacks that killed nearly 3,000 people signals a deepening battle over the independence of the military commission at the naval base at Guantanamo.

McCall provisionally scheduled the plea hearings to take place over two weeks starting Jan. 6, with Mohammed — the defendant accused of coming up with using commercial jetliners for the attacks — expected to enter his plea first, if Austin’s efforts to block it fails.

Austin is seeking to throw out the agreements for Mohammed and fellow defendants Walid bin Attash and Mustafa al-Hawsawi.
