Britt Hume over at Fox news makes a good point, which underscores the need for skepticism about W. Mark Felt's claim to be Deep Throat:

Hume: "Bob Woodward and Carl Bernstein, who are in a position to say finally who they consider to be Deep Throat, are not confirming this. If this person really is the guy, and he's now saying I'm the guy, if he is why not...why not come ahead and say?"

Neil Cavuto: "But they made a vow that they would wait until this person died, right?"

Hume: "Who did they make the vow to? The person you make a vow to in the situation... if you make a vow to your source and your source comes forward, that eliminates the reason for privacy. Unless you think the source is a little batty. And of course if you think the source is a little batty that's not something you want to say, after all, this is a person who supposedly gave you all this great information.

You never know about something as long-running as this saga, to what extent someone in some way may be trying to capitalize on the famous nature of this whole question of who is Deep Throat."

Indeed.

Mr. Feldt's grandson, who came out just a while ago to make a statement on Mr. Felt's behalf, did not exactly inspire confidence in the credibility of Mr. Felt's claim. The giggly grandson provided no information which would further substantiate the claim by Mr. felt to be the Deep Throat of Watergate.

Update at 3:02 p.m. Pacific time: Fox News is now reporting that the Washington Post itself has now confirmed that Mr. Felt is indeed Deep Throat.

Well, so much for Woodward and Bernstein's surprise.
