Kellyanne Conway stands 'in a class of her own’ when it comes to slimy White House power games: Ex-Trump aide

Former Trump White House aide Cliff Sims alleges that White House counselor Kellyanne Conway is by far the nastiest and most vicious "viper" in the president's inner circle.

As reported in a review by The Guardian, Sims' new book -- entitled "Team of Vipers" -- claims that Conway is constantly backstabbing her colleagues by bad-mouthing them to reporters, even as she then attacks those reporters for writing "fake news" stories about White House infighting.

"Kellyanne stood in a class of [her] own in terms of her machinations," Sims writes of Conway's constant scheming. "I had to admire her sheer gall."

Sims says that Conway routinely trashed top Trump officials including Jared Kushner, Reince Priebus, Steve Bannon and Sean Spicer to reporters, and he also claims she spilled the beans to reporters about conversations she'd had with Trump that were supposedly private.

Elsewhere in the book, Sims laments that White House Press Secretary Sarah Huckabee Sanders often went into press conferences without complete or accurate information, which he says reflects the fact that she "didn’t press as hard as she could have for the rock-bottom truth."

This meant she would have to perform "gymnastics with the truth would tax even the nimblest of prevaricators, and Sanders was not that."
