Ft. Hood hearing tomorrow

From NBC's Amna Nawaz
Sens. Joe Lieberman (I-CT) and Susan Collins (R-ME) confirmed in a press conference today, that their Homeland Security and Governmental Affairs Committee investigation into the shootings at Fort Hood will continue, beginning with a hearing tomorrow.

Lieberman said he supports the military and Justice Department investigations into the shootings, and looks forward to the result of John Brennan's report on intelligence sharing to President Obama, but "that does not mean the rest of us can just sit back and watch."

The Fort Hood shooting, he said, heĀ  believes was a terrorist attack, "the most destructive terrorist attack on America since 9/11."

He said Congress has a constitutional responsibility to oversee the operations of the Executive Branch, and that the committee's investigation would focus on answering two questions:

(1) What did the federal government know about Maj. Hasan and could actions have been taken to prevent the attack?
(2) How does the Ft. Hood shooting affect our understanding of and defense against "violent Islamic extremism" and homegrown terrorism?

This investigation, he said, would, in effect, be a continuation of the work his committee has already been doing on homegrown terrorism, its effects, and how to defend against it.

Drawing a comparison to the work of the 9/11 Commission, Collins added that the investigation is necessary to ask "troubling questions" about whether there may have been "inexcusable gaps and communications failures" in intelligence and information sharing that might have prevented the attack.

Tomorrow's hearing will focus on information already available in the public record.
