Capping a day of less-than-absolute denials, Rep. Anthony Weiner went on “The Rachel Maddow Show” Wednesday night, where he offered jokes but no further explanation of whether a photograph of an underwear-clad man’s groin was of him.

“Am I allowed to say I wish?” he joked on the MSNBC show, when asked if the lewd photo was him or not. “Jon Stewart last night assured his public that it wasn’t me for reasons that are somewhat embarrassing. But I’ll leave it to your viewers to make that determination.”

Weiner, yet again, hedged his answer when pressed by Maddow, saying, “Stuff gets manipulated.”

“Maybe it started out being a photograph of mine,” he continued, but was “was taken out of context” and sent to a young woman in Seattle via twitter.

“I’m going to say that I can’t say with certitude it’s me or it’s not,” he said, hours after giving another interview to MSNBC in which he first said he couldn’t “say with certitude” that he wasn’t the man in the photo.

Also on Wednesday night, House Minority Leader Nancy Pelosi (D-Calif.) made her first comments on the scandal. “I am a late-comer to the issue,” she told ABC News. “I have confidence in Anthony Weiner that if an investigation is in order, that will take place.”
