Tonight... get on the record with Greta!

Secretary of State Colin Powell (search) suggested to members of the commission looking into the terror attacks of September 11, 2001, that even if Usama bin Laden (search) had been caught or killed before 9/11, the attacks may still have happened.

Powell is testifyed today on Capitol Hill before a federal panel that is probing the attacks. It blames the administration -- and the previous one -- for not doing enough against Bin Laden and his Al Qaeda network (search) before 9/11.

Powell says there was evidence the suicide hijackers already had their plans and were in the United States -- so any major attack against Al Qaeda (search) may not have affected their ability to carry out those plans.

He adds there are still fears the U.S. could suffer another terror attack on its own soil. Powell says even though progress has been made in targeting Al Qaeda leaders, the network has many "tentacles" all over the world.

In addition to Secretary Powell, former Clinton administration Secretary of State Madeleine Albright (search) also testified before the panel. Later in the day,as former Clinton Defense Secretary William Cohen (search) and current Bush administration Defense Secretary Donald Rumsfeld (search) are also expected to testify.

We'll have the latest on the testimony including a live report from Washington, D.C. for you this evening.
