Jon Stewart grills Judith Miller on 'The Daily Show'

Jon Stewart tore into former New York Times investigative reporter Judith Miller on "The Daily Show" Wednesday for her infamous role in the lead-up to the war in Iraq.

"I believe that you helped the administration take us to, like, the most devastating mistake in foreign policy that we've made in, like, 100 years," Stewart told Miller at the start of the interview. "But you seem lovely."

Miller, who was there to promote her new book, "The Story: A Reporter's Journey," said she was misled by her sources about intelligence on weapons of mass destruction in Iraq, but that "everyone got it wrong."

"I wasn't alone, I had lots and lots of company," Miller said. "The intelligence sources we were talking to had really never been wrong before."

"That's why I wrote the book," she told Stewart. "I hoped that people like you would read it and determine that it was really, really hard to do this kind of reporting."

Miller's now-debunked Times reports bolstered the Bush administration's case for the 2003 invasion of Iraq, but she denied the faulty intelligence came from either former President George W. Bush or former Vice President Dick Cheney.

“The information came from the men and women who had steered me right on al-Qaida before 9/11," Miller said. "They had never led me astray."

But the "Daily Show" host wasn't satisfied.

"You had to shift, with energy, the focus of America from Afghanistan and al-Qaida to Iraq. That took effort," Stewart said. "Somebody pointed the light at Iraq. And that somebody is the White House and the Defense Department and [Donald] Rumsfeld."

Later in the interview, Stewart asked Miller if she had been "manipulated."

"All journalists are manipulated and all politicians lie," she replied. "They all try and spin."
