NPR senior editor Ron Elving read Cliff Sim's new White House tell-all, Team of Vipers, and dished Tuesday with CNN's Brooke Baldwin on some of the juicier revelations.

In one interaction with then-House Speaker Paul Ryan, Elving described President Donald Trump "wandering off" during a complicated discussion of tax reform.

"He literally gets up while Paul Ryan is in mid-description and wanders out of the Oval Office and down the hallway into a side room where one can hear the television being switched on," Elving said, adding the "eventually" the vice-president had to go retrieve the easily distracted commander in chief.

Elving said the new book confirms that chief of staff John Kelly hated his job.

"He basically said 'this is the worst job I've ever had, they couldn't do anything to make me happier than to put me out the door,'" Elving said, quoting Kelly.

Elving said that Sims was also "pretty rough" on White House spokesperson Kellyanne Conway, referring to her as "the American Sniper," and had equally harsh words for Reince Priebus and Sean Spicer.
