The newest security threat at the winter Olympics could be toothpaste.
The U.S. is warning airlines that people could be carrying explosives in toothpaste or cosmetics on their way to Sochi.
This new threat appears to apply mostly to flights out of Europe and Asia. There is no known threat to the U.S.
The opening ceremony is tomorrow, but some events are already under way there today. Officials say they're actually more concerned about security travel hubs around the Olympics than the actual games.
There's been no word from the White House on this latest threat.
