Earlier this week, Fox News host Megyn Kelly went on an epic rant about the lack of truth in politics. It took only two days for that passion to fade.

In a panel discussion on yesterday's edition of Kelly's show, America Live, Fox News contributor Marc Thiessen rejected guest Simon Rosenberg's claim that only 3 percent of taxpayers claiming business income would pay higher taxes under President Obama's tax plan -- a claim that happens to be true.

Kelly could have used this exchange to put her claimed passion for truth in the political process into action by trying to suss out who -- Rosenberg or Thiessen -- was telling the truth on business taxes. Instead, she brought the segment to a close by saying, “And on that note, we have to agree to disagree.”

This is the same Megyn Kelly who -- just two days earlier on the very same show -- forcefully asked the question, “Does truth matter anymore at all in the political process?” But, when presented with a golden opportunity to pursue that truth, Kelly punted.

We pointed out that Kelly should try enforcing those standards a little closer to home at the post-truth network before worrying about what others are doing, but Kelly doesn't even have to go that far. Her own show is the perfect place for her to put her words into action -- if she would actually do that.
