The revelation comes in the 2016 Democratic presidential nominee's new memoir, titled “What Happened,” which provides Clinton's perspective on what led to her stunning loss last November to President Trump.

In recounting what happened during NBC's "Commander-in-Chief Forum" on the USS Intrepid just two months before Election Day, Clinton slammed Lauer for focusing too much on the email controversy that dogged her throughout the campaign.

“You’re communicating on highly sensitive topics. Why wasn’t it more than a mistake? Why wasn’t it disqualifying?” Lauer, a longtime co-host of NBC's "Today Show" asked.

“Now I was ticked off,” the former secretary of State wrote. “NBC knew exactly what it was doing here. The network was treating this like an episode of 'The Apprentice,' in which Trump stars and ratings soar."

"Lauer had turned what should have been a serious discussion into a pointless ambush. What a waste of time," Clinton added.

“I can’t say I didn’t fantasize about shaking some sense into Lauer while I was out there,” she also wrote.

Clinton also believed Lauer gave Trump, who appeared separately after Clinton's 30 minutes on stage, a "soft-pedal" interview.

“I was almost physically sick,” Clinton wrote.
