It was a joke.

That's how Anthony Weiner described his comment earlier this week that suggested he had inside information into Hillary Clinton's 2016 plans.

"Have you ever heard that sometimes people say, 'Yes, but if I tell you I'd have to kill you?'" Weiner said tonight. "It was a joke, everyone laughed, it was a joke."

When pressed by ABC News after a New York City mayoral debate, he declared: "I have no insight into campaign 2016. I'm struggling right here with 2013."

Team Clinton isn't laughing.

The latest dustup for Weiner came Monday night at a forum sponsored by BuzzFeed when he said he knew what role his wife, Huma Abedin, would play in a Clinton presidential campaign.

"I do," Weiner said. When pressed for an answer, he said: "I'm not going to tell you."

Nick Merrill, a spokesman for Clinton, departed from previous protocol of steering clear of commenting on Weiner and said bluntly: "We have absolutely no clue what he was talking about."

Weiner, whose candidacy for mayor of New York has been deeply tarnished by another sexting scandal, is struggling to be viewed as a credible candidate in the race. He bristled when asked about the Clinton comments.

"I'll try to make the jokes more obvious," Weiner said, before turning away.
