Richard Grenell tried to erase the tweets he thought might embarrass the Romney campaign. - Slate Magazine: That was the old Richard Grenell—longtime communications director for a string of United Nations representatives and ambassadors. On Thursday, Mitt Romney’s campaign hired Grenell as a full-time spokesman on national security matters. His tweets took on world-historical importance. Politico’s Alexander Burns combed Grenell’s feed and found jokes about the Gingriches (“Newt: My 1st Lady knows what it’s like to be 2nd and 3rd…”) and Rachel Maddow (“Rachel Maddow commercials can't possibly attract any viewers, aside from Bieber fans #DeadRinger”). ThinkProgress ran its own report only five hours after sort of saluting Romney for hiring an openly gay spokesman.
