Even before President Obama took the oath of office, the threat of a terror attack loomed large. The "New York Times" is reporting intelligence officials were worried that Somali terrorists were plotting to detonate explosives during the event. The threat turned out to be bogus. but no one of course knew that at the time.

COOPER: I understand President Obama even canceled a rehearsal of the inauguration. What was -- what was -- when was the president actually briefed? And do you know what his reaction was?

BAKER: Well, he was -- he was kept up to date in the -- in the few days leading up to the inauguration. There's one moment in particular we write about in the magazine. The night before the inauguration, his counterterrorism adviser, John Brennan, and a couple of foreign policy advisers jump into the limousine with him as he's heading off to one of the inaugural events to tell him the latest that they had heard, and what -- everything that was being done about this.

One of the things that the new administration and the old administration agreed was they would keep Robert Gates, the defense secretary, away from the inauguration in a secure location, a secret location. Just in case the worst happened and everybody in the line of succession were to be killed in a catastrophic event, he would be able to take over the presidency.

It turns out the threat was a false rumor intentionally planted by a rival terror group.

A deadly shooting in Las Vegas. And police say the gunman was angry about his social security benefits. This video with the obvious audio there posted on YouTube, captured some of that gunfire and commotion. One security officer was killed, so was the shooter. Police say 66-year-old Johnny Wicks opened fire with a shot gun when he walked into the courthouse yesterday. Here's how one witness described the shooting.

The Johnny who went into the courthouse I passed him as I was walking into the fully courthouse, went through security was talking to my attorney on the matter. And we heard the gunshots, it sounded like popcorn. It wasn’t as loud as the video shows because we were in the building but we all ,you know ,I walked outside to the 4A of the entrance of the fully building, looked down to bay window and saw 5 marshals and a couple of pro-officers with their guns drawn. Shooting, well, their hands showed they had just finished shooting towards with the perpetrator was.

A deputy marshal was also shot by Wicks. He is in stable condition. Police say Wicks was upset over losing an appeal for more social security benefits.
