In The Unknown Known, Oscar-winning documentarian Errol Morris (The Fog of War) turns his infamous interrotron on former Secretary of Defense Donald Rumsfeld. He was one of the key architects of the U.S. response to the attacks of September 11th under President George W. Bush, which included wars in Iraq and Afghanistan.

The title of Morris’ documentary, out April 4, is taken from a controversial response Rumsfeld gave in February 2002 when, as Secretary of Defense, he was prodded about the lack of evidence concerning “reports” propagated by the Bush administration that Iraq was supplying weapons of mass destruction to terrorist groups:

Family members and victims of the Sept. 11, 2001, terrorist attacks joined three members of Congress on Wednesday in calling on the Obama administration to declassify portions of a congressional investigation that addresses allegations of possible Saudi government support of the hijackers.

The report, released by a joint panel of the House and Senate intelligence committees in December 2002, contains 28 redacted pages that family members and victims say would shed new light on the hijackings. At the time the report was released, the Bush administration classified the material, but numerous sources reported it dealt with the Saudis.

A psychologist who examined one of the defendants on trial at Guantanamo Bay, Cuba, in connection with the terrorist attacks of Sept. 11, 2001, concluded that the high-value detainee was mentally incompetent, raising questions about his fitness to stand trial, according to individuals familiar with the finding.

For three days in January 2009, Xavier Amador, a professor at Columbia University, interviewed Ramzi Binalshibh, an al-Qaeda operative and protege of alleged Sept. 11 co-conspirator Khalid Sheik Mohammed. He determined that Binalshibh didn’t understand the proceedings against him and suffered from delusions, said one of the individuals who has reviewed the case.

A New York federal appeals court has restored Saudi Arabia as a defendant in a lawsuit brought by thousands of people affected by the Sept. 11, 2001, attacks.

Former Florida Sen. Bob Graham, who co-chaired a joint congressional inquiry into the attacks, called the ruling a "very significant breakthrough," BrowardBulldog.org reported Tuesday.
