Today's object lesson comes courtesy of Richard Grenell, a newly-named campaign official with the Mitt Romney campaign. Grenell reportedly has removed thousands of tweets that -- again reportedly -- made snarky comments about the media and various women Democrats.
His response was the old attempt used by those caught with their hand in the cookie jar: The tweets were all meant to be jokes, he told the Huffington Post: "My tweets were written to be tongue-in-cheek and humorous but I can now see how they can also be hurtful. I didn’t mean them that way and will remove them from twitter. I apologize for any hurt they caused."
