You’ll remember that Breitbart is the same fella who selectively edited the video of a speech by Shirley Sherrod, then an Agriculture Department official, to make her look like an unrepentant racist. The opposite was true. That makes him a questionable source for attacks on a sitting member of Congress. That being said, the new photos demand an answer from Weiner. If there is a reasonable explanation, it’s best to rip the band-aid off sooner rather than later. But if the explanation is remotely unsavory, it’s best that he move even faster to head off the embarrassment to come from new and possibly even more damaging revelations to come.
