Surprise, surprise: it turns out Fox's story about when it got Doug Hampton's letter regarding John Ensign's affair was inaccurate.

Fox News received Doug Hampton’s letter about Sen. John Ensign’s adulterous affair three days earlier than the network reported, according to information obtained exclusively by the Las Vegas Sun.

Fox said it didn’t receive the letter until June 15, when it arrived as an attachment to an e-mail. But FedEx tracking of a “priority envelope,” which a reliable source said contained the hard copy, shows it was delivered on the morning of June 12.

That would mean the national news organization had additional time to investigate and report Ensign’s affair before the senator’s own admission of the relationship with Hampton’s wife, who worked for the senator’s leadership political action committees.

The earlier delivery date also leaves a larger window of time for someone who either worked at the conservative network or was close to it to tip off Ensign.

On Tuesday, Tom Lowell, senior producer of “America’s Newsroom,” declined to comment on the FedEx delivery. Hampton had addressed his June 11 letter to the co-anchor of “America’s Newsroom,” Megyn Kelly.
