Rep. Anthony Weiner has scheduled a press conference at 4pm ET in New York, presumably to address the latest accusations from Andrew Breitbart. So here’s a thread to discuss as it happens; we shall see what we shall see.

On Twitter, I’ve been getting attacked like crazy all morning; apparently I’ve now “lost all credibility.” This is at least the 50th time this year that I’ve finally lost all credibility. I guess it keeps growing back or something.

And I’ve been getting a flood of hate mail, much of it demanding that I “apologize” for something. So here’s my official response to this demand:

Not a freaking chance. If Weiner admits to sending the pictures in question, I’ll be surprised and disappointed, but I’m never going to apologize for calling it as I see it.

And I’m certainly never going to apologize for pointing out that Andrew Breitbart is a sleazy fraudster, with a well-documented and very tawdry history of deception.

So to those demanding that I apologize: try holding your breath until you turn blue. Maybe that will do it.

And there we have it; Rep. Weiner has admitted to sending the pictures, in an abject apology. But he says he’s not going to resign.

Just to be absolutely clear about this: yes, Andrew Breitbart got this one right. But again, I will never apologize for doubting his credibility. He’s smeared too many innocent people, he does not deserve the benefit of the doubt, and getting it right this one time does not change those facts.
