Investigative reporter Sharyl Attkisson resigned from CBS News in March, but she didn’t give up reporting. Attkisson’s analysis of the newly released Benghazi documents can be found on her personal website, and it’s essential reading for anyone who has been following the story from the beginning.

Rep. Jason Chaffetz (R-Utah) told me today that the government apparently tried to keep the [deputy national security adviser Ben] Rhodes email out of Congress and the public’s hands by classifying it after-the-fact.

“They retroactively changed the classification,” Chaffetz says. “That was an unclassified document and they changed it to classified.”

Attkisson also spoke to Sen. Lindsey Graham.

Today, Sen. Lindsey Graham (R-SC) called the Rhodes email the “smoking gun” showing the “political manipulation by the White House” after the attacks.

​“The political shop at the White House took over early on,” Graham told me. “They understood it was a terrorist attack, that they had a political problem, and were going to handle it politically. They weren’t going to entertain anything other than what they wanted the public to hear.”
