Homeland Security Update: Bret Baier

We asked Pentagon correspondent Bret Baier to update us with the latest on the interrogation of 9/11 mastermind Khalid Sheikh Muhammed:

Do we know if Khalid Sheikh Muhammad is being interrogated in the U.S.?

Do officials believe he can lead us to bin Laden?

Is it true that Khalid is uncle to Ramzi Yousef- the architect of the 1993 WTC bombing, and if so, are more of his family members being interrogated?

Are there signs that he will ever be brought to trial?

Terrorism experts say the interrogation report is giving a clearer picture of how Al Qaeda operates. Can you expand on that at all?

Has he helped officials thwart any terror plans since he's been captured?
