Jon Stewart is not going quietly as he prepares to leave The Daily Show.

On Wednesday's show, Stewart's guest was former New York Times reporter Judith Miller, whose erroneous reporting that Saddam Hussein had weapons of mass destruction helped spur the U.S. invasion of Iraq. Stewart spent much of the interview accusing Miller of essentially being a mouthpiece for the Bush administration.

Why is Jon Stewart really leaving The Daily Show?

"I believe that you helped the administration take us to the most devastating mistake in foreign policy that we've made in 100 years, but you seem lovely," Stewart said.

Miller, who is currently a commentator for Fox News, came on the show to promote her new book, The Story: A Reporter's Journey. As she did in a Wall Street Journal op-ed earlier this month, Miller defended her reporting on Iraq, telling Stewart that she was relying on sources that she had used several times before on stories that earned her a Pulitzer Prize.

"That's why I wrote the book," Miller said. "I hoped that people like you would read it and determine that, one, it was really, really hard to do this kind of reporting. I wasn't alone. I had lots and lots of company. And that the intelligent sources we were talking to had never been wrong before."

Stewart didn't let up, telling Miller: "Not everybody got it wrong. ... You don't believe that you were manipulated?"

"All journalists are manipulated," Miller responded.

Eventually, an exasperated Stewart cut the interview short, telling Miller: "Obviously we are never going to see eye to eye on it. I appreciate you coming on the show. These discussions always make me incredibly sad because I feel like they point to institutional failure at the highest levels and no one will take responsibility for it, and they pass the buck to every individual other than themselves. And it's sad."

Miller resigned from the Times in 2005.
