Did Miller Have Second Source?

CNN has this headline:

New York Times reporter disclosed conversation with second source

Now this would be very interesting and would keep alive my theory of Bolton involvement but I wonder if someone at CNN just messed up the headline.....that it should be 2nd conversation with source not 2nd source.

UPDATE: 3:24 pm I called CNN Washington Bureau and they initially said that the headline would be correct. I pressed a bit and pointed out the AP story in their post does not address the substance of the headline. At that point they said their reporters are still in the field but they would check it out. Several hours later and the headline is still there so not sure what that means.
