It’s a good question. He may have done, although I can’t immediately put my finger on it. Also, it depends what you make of that mysterious letter to the Hawaiian hospital, posted on the website and used for fundraising, then taken down. Did Obama write that, or not? Still no answer.
What’s more telling to me is the on-line COLB. It was posted by an anonymous third party on Daily Kos, which is not an Obama web site. I’m pretty sure that Obama has NEVER spoken directly about this COLB, or said that it was real, but has allowed his flunkies to do so.
The nearest it came was the assertion that it was genuine on the FightTheSmears website, which was sponsored by Obama but still has deniability—i.e., he could explain that his friends and flunkies were mistaken about it and he forgot to correct them. And, of course, FightTheSmears has now vanished.
Interesting, because Obama has not hesitated to lie about other matters which are less legally dangerous. For instance, he has said that “I was NEVER a Muslim,” which is clearly an outright lie, since he was born a Muslim, adopted a Muslim, trained as a Muslim, studied the Qran, went to the mosque for prayers, etc. He could have said “I am not a Muslim,” and there would be no way to disprove that. But religion is a private matter, in modern thinking a matter of opinion not fact, so he was safe in saying that.
Besides that falls under Al Taqqiyah...
