Chuck Hagel: Iran 'red line' should not be discussed publicly

Senator Chuck Hagel before the Armed Services Committee: 'I think the President has gone as far as he should go publicly. He has said clearly that in his words, he has Israel's back. He said his policy is not to allow the Iranians to get a nuclear weapon. What constitutes when action would be taken, that is always something that should not be discussed publicly or debated in the public domain.'
