RADDATZ: And while Russia takes the lead on securing Sochi, the U.S. has repeatedly offered its assistance. FBI agents will be on the ground during the games. And two U.S. navy ships will be in the nearby Black Sea.
DEFENSE SEC. CHUCK HAGEL: Whatever we can do we want to do to help.
RADDATZ: But one informal request by Russia's top general to joint chiefs chairman Martin Dempsey for American roadside bomb jamming technology may go unheaded.
BARBERO: As far as jamming technology, we're not going to share that.
RADDATZ: Why not?
BARBERO: Because it's very closely held. If you understood how we jammed, you could defeat it.
RADDATZ: The key to stopping any terror attack, of course, is intelligence. Russia, the U.S. and others are sharing whatever possible.
RADDATZ: But like anything else, it is not perfect -- Jon.
KARL: Thank you, Martha.
Let's bring in Congressman Peter King. He is the chair of the House counterterrorism and intelligence subcommittee. Thank you for joining us, Congressman.
KING: Thank you, Jon.
KARL: We saw this weekend in the New York Times Olympic athletes are worried about their own security, some of them. Can you reassure our athletes going to Sochi that they're going to be safe?
KING: I cannot give them 100 percent guarantee. The fact is that these are going to be very much threatened Olympics. Probably more than any we've had in our past, more than Greece, certainly more than London or China. So, no, it's -- I mean, everything is being done by the United States. But the fact is this is a dangerous region in Russia by the north Caucuses. There are active terrorist organizations there. And quite frankly, the Russians have not been cooperating with us or with other countries anywhere near the extent that, for instance, the Greeks or the Chinese or the Brits did.
KARL: But what about the suggestion to our athletes that they not wear their uniforms outside of the Olympic venues. Has it really come to that that American athletes have to hide the fact that they're American athletes?
KING: Yeah, I think it's an indicator of just how seriously our government takes this, the fact that there are real threats there.
And even though Putin talks about the ring of steel around the main Olympic venue, the fact is once you get outside that venue or even going from venue to venue there is real vulnerability. So I think that's -- I would advise the athletes that do everything they're asked to do by the security team, by the State Department, by the FBI, because they may feel safe, they may feel secure, wander off or wear some indicator that they're from the U.S. and just leave themselves open as a target.
Now this is a dangerous situation. Hopefully things will work out, but it's nowhere near ideal.
And again, I can't emphasize enough, the Russians have not been cooperative as far as sharing intelligence.
Again, the Greeks did, the Chinese did, the Brits did, the Russians are not and there's is the most dangerous.
KARL: Well, you've said that now twice, the Russians have not been cooperative. But we've just heard in Martha's story that they have asked for some equipment, technology that we're unwilling to share.
