AP’s Sunday story revealing that the U.S. and Iran had held secret talks before the announcement of a nuclear deal contained this paragraph:
The AP was tipped to the first U.S.-Iranian meeting in March shortly after it occurred, but the White House and State Department disputed elements of the account and the AP could not confirm the meeting. The AP learned of further indications of secret diplomacy in the fall and pressed the White House and other officials further. As the Geneva talks appeared to be reaching their conclusion, senior administration officials confirmed to the AP the details of the extensive outreach.
Contrary to a number of accounts since Sunday, AP did not sit on the story for several months. We aggressively pursued the story throughout that period, trying everything we could to get it to the wire. In fact, some of the information we were tipped to in March turned out to be inaccurate.
“A tip is not a story,” said AP Washington Bureau Chief Sally Buzbee. “AP was attempting to confirm, to its standards, what had happened. We published the story when we had the vital details that we needed satisfactorily confirmed.”
To quote from AP’s News Values and Principles:
“The AP routinely seeks and requires more than one source. Stories should be held while attempts are made to reach additional sources for confirmation or elaboration. In rare cases, one source will be sufficient – when material comes from an authoritative figure who provides information so detailed that there is no question of its accuracy.”
