John Edwards may have publicly admitted to his extramarital affair with Rielle Hunter. But after chasing the story for nearly a year and being repeatedly referred to as “tabloid trash” by the man who ended up admitting his denials were all lies, the National Enquirer isn’t anywhere close to being finished with the story.

The Enquirer offers new details about Edwards’ relationship with Rielle Hunter and the concerted effort his supporters made to keep her out of the public eye as he prepared to appear on national TV recently to address the Enquirer’s reports.

It is a no-brainer what’s going on here: The Enquirer is trying to goad and bait Edwards into filing a libel lawsuit against the tabloid. As any good journalist knows, the best defense against libel is the truth; to disprove the Enquirer’s claims, Edwards would have to demonstrate that what the Enquirer said about him—that he is the father of Hunter’s baby—is false.

And that’s how the Enquirer would get the DNA test it’s been trying to arrange for months.

So, for all his huffing and puffing and self-righteous indignation about the “tabloid trash,“ don’t expect Edwards to be filing any libel lawsuits against the National Enquirer.

Discovery is a two-way street.
