The Drudge Report strikes again!  Actually, The Drudge Report wasn't the first media outlet to report that Prince Harry was serving in Afghanistan.  However, I believe it was the first English-language source for this news.

Matt Drudge is secretive, so we may never know exactly how he learned this information.  All I can say is that if I were someone who wanted to leak a story -- say, in order to get Prince Harry sent home -- I'd contact the Drudge Report before anyone else.
