WASHINGTON (AP) -- The first Capitol Hill hearing on the Fort Hood shootings is set for this morning.

The Senate Homeland Security Committee will look at the threat posed by homegrown terrorism and chairman Joe Lieberman says it also wants to know whether the shooting was the result of intelligence failures.

Lawmakers are concerned that federal agencies may not be sharing intelligence information.

Lieberman and the panel's top Republican, Susan Collins, say the congressional investigation wont get in the way of other ongoing probes.
