While detailing some of his foreign policy objectives, Christie made clear that Islamic State is an immediate and ongoing threat.

He said to the best of his knowledge, they are not pursuing a nuclear weapon and once they have it, they will use it.

Christie also criticized President Obama for not recognizing Islamic State as a threat early enough to stop them.
