Here is a transcript of the public travel announcement/message:
"Hello. This is TSA Administrator John Pistole. On behalf of the more than 50,000 Transportation Security Officers across the country, thank you for being our partners in security. For your safety, we have instituted new screening procedures at checkpoints. Please take a moment to read the materials available about these procedures and your options as a passenger. We appreciate your patience as we all work together to keep travel safe."
