With only 16 days until the opening of the Olympic Games in Sochi, teams representing at least five countries say they've received emails threatening terror attacks at the games. The countries are Germany, Hungary, Italy, Slovakia and Slovenia.
In the U.S., officials continue to express concerns about whether extensive security precautions, including the now-famous "ring of steel," will be adequate to protect visitors to the games.
House Homeland Security Committee Chair Michael McCaul told ABC News today that precautions should keep the Olympic Village safe and secure, but "outside of that, I can't give any guarantees."
Travel companies have not reported cancellations, but at least one Olympic athlete — long track speed skater Tucker Fredricks — has told his family to stay home in Janesville, Wisconsin.
Here & Now's Robin Young checks in with Olympics sports writer Phil Hersh, who says, "If I did not have to go to these Olympics to cover them, I would not be going."
