BILL HEMMER, CNN ANCHOR: U.S. authorities say they have seen a significant jump in terrorist threats against U.S. interests worldwide. Such threats have prompted American forces in the Persian Gulf region to go now on high alert. Here in the U.S., lawmakers taking a closer look at the deadly attack against the USS Cole. Carl Rochelle, live at the Pentagon now, who's watching this story with more now. Carl, hello to you.</s>CARL ROCHELLE, CNN CORRESPONDENT: Hello, Bill. This is the Senate Armed Services Committee that was sort of postponed last week because the Defense Department witnesses were not quite ready to testify. They are there this morning and one of the things that has come up -- the hearing, by the way, is still going on right now -- Senator John Warner, the chairman of the committee, raised questions about that timeline. He said questions need to be answered about why that timeline changed and he was told that there may be some further revision in it. No details on that yet, but we expect they'll get into that when they go behind closed doors in just a bit. Now, General Tommy Franks, who is the Central Command commander and in charge of the Cole, said they plan to get to the bottom of what happened.</s>GEN. TOMMY FRANKS, U.S. CENTRAL COMMAND: We're determined to get to the bottom of this. We'll put the events that led up to Cole under a microscope. And, in fact, we've begun that process. We will find the facts we need to find, and we'll use the lessons that we learned from Cole to provide the best possible force protection for our troops in one of the most dangerous regions in the world.</s>ROCHELLE: Was there a threat in advance? That is one of the questions they'll be asked behind closed doors and that's where they plan to go in just a bit -- Bill.</s>HEMMER: All right, Carl. Carl Rochelle from the Pentagon. Thanks, keep us posted.
