Who are the sources? Can you link me their claims?
I realize that's an unsatisfactory answer for many. But it's how journalism has to work sometimes.
> We have on the record sources
You are not on the record if you are anonymous.
> On-the-record, in journalism, means anything in a communication may be publicly disclosed
> "On the record": all that is said can be quoted and attributed.
> "Unattributable": what is said can be reported but not attributed.
