Job One: Reassure the public you knew all about this and are hardly surprised, because you don't want them to think you're so out of the f***ing loop this snuck up on you. So everyone's in "Oh, of course I knew, it was all so obvious!" in-the-know cool-kid mode.
Job Two: The trickier one-- attempt to explain how it can be you knew all about this but didn't report it, or bother to do the minimum threshold of follow-up. Bear in mind, the National Enquirer is a small outfit. When they assign three or four people to a story, that's a substantial fraction of their entire component of reporters and photographers.
It's nothing for a network news organization to assign three or four people to a story -- they've got hundreds of unpaid interns chomping at the bit to do something besides edit and fetch coffee, for God's sakes. So even if they didn't want to send a reporter, they could have sent a dozen recent graduates out there to get the story... which they would have gotten. This was not exactly a Phillip Marlowe murder mystery here.
Note that Job One and Job Two are basically impossible to square in any satisfactory manner. But they're quite righteous and smugly self-complimentary about both.
