Ebola in New York - we'll have the latest news on the patient, and talk to infectious disease experts.
Washington (CNN) - The chair of the Senate Intelligence Committee has read the reports on terrorist threats to the Sochi Olympics, and she has a message for anyone traveling to the Winter Games: Watch your backs.
"The threat stream is credible, I think it's real," Sen. Dianne Feinstein, D-California, told CNN's "The Lead with Jake Tapper."
Feinstein noted at least one terrorist group – the Caucasus Emirate – has made threats and "is conceivably capable of carrying out an attack."
"People going to the Olympics should be careful, I think they should watch their backs, I think they should stay out of crowds if they can," said Feinstein.
The Russians have security forces, good intelligence, and know the problems inherent in areas surrounding Sochi, said the senator.
Still, Americans should carefully evaluate the risk of attending the Sochi Olympics; Feinstein said she would not go, unless a family member was competing.
"If I had a son or daughter performing in the Olympics, I would go. Now that I don't, I probably would not," said Feinstein. "I've seen the threat stream, and I know the opposition, and the opposition is dogged. It is continuing, it is threatening, and hopefully arrests can be made and any attack can be stopped."
The United States is also advising airlines with direct flights serving Russia to be aware of the possibility that explosive materials could be concealed in toothpaste or cosmetic tubes.
"This is the world we live in now, and it's just terrible it's come to the Olympics," said Feinstein.
