Biden: "Russia’s use of chemical weapons would 

trigger a significant response."

Doocy:  “What does that mean?”

Biden:  “I’m not going to tell you.  Why would I tell you? 

You got to be silly.””

Doocy:  “The world wants to know.”

Biden:  “The world wants to know a lot of things.  

I’m not telling what the response would be,

         then Russia knows the response.”
