Khalid Sheikh Mohammed, the suspected mastermind of the Sept. 11 attacks, referred to Defense Department for a military trial at Guantanamo Bay by Attorney General Eric Holder, who suggests he knows more than Congress when it comes to the case.

Congress tied the Obama administration's hands in trying the alleged mastermind of the Sept. 11, 2001, terror attacks and his accomplices, Attorney General Eric Holder said Monday, announcing that he was left without a choice and has referred the cases to the Defense Department for trial. 

In stark language, Holder lambasted Congress for imposing restrictions blocking any detainees from being tried in the U.S., saying that the "unwise and unwarranted restrictions" undermine the U.S. in counter-intelligence and counter-terror efforts.

As a result, Holder said Khalid Sheikh Mohammed, who has been incarcerated in Guantanamo Bay, Cuba, since 2006, after being captured in Pakistan in 2003, and four alleged Sept. 11 co-conspirators will face prosecution by a military commission in Guantanamo.
