Washington (CNN) Former White House communications aide Cliff Sims describes scenes of an "absolutely out of control" White House staff, President Donald Trump berating the then-speaker of the House from his own party over loyalty and the President walking out of policy meetings in his upcoming book, according to excerpts published by The Washington Post.

The stories are recounted in Sims' book "Team of Vipers," out next week and obtained in advance by the Post

Trump took Paul Ryan to task over Ryan's loyalty to him after the former House speaker criticized Trump's handling of the deadly 2017 Charlottesville, Virginia, rally, according to the excerpts.

"Paul, do you know why Democrats have been kicking your a-- for decades? Because they know a little word called 'loyalty,'" Trump told Ryan over the phone. "Why do you think Nancy [Pelosi] has held on this long? Have you seen her? She's a disaster. Every time she opens her mouth another Republican gets elected. But they stick with her...Why can't you be loyal to your president, Paul?"

Trump also brought up how Ryan distanced himself from Trump in 2016 after the release of the "Access Hollywood" tape, in which Trump could be heard bragging about being able to grope women.
