“I know those people in the White House," Haley said on ABC's "This Week with George Stephanopoulos.” ADVERTISEMENT

"These people love their country and respect our president. I've never seen or heard the type of toxic language that they are talking about ... No one questions the stability of the president,” she continued.

Her remarks come after Michael Wolff, the author of "Fire and Fury: Inside the Trump White House," claimed that "100 percent of the people around" Trump question "his intelligence and fitness for office," including "senior advisers, family members, every single one of them."

"I will tell you the one description that everyone gave, everyone has in common: They all say he is like a child," Wolff said Friday on NBC's "Today."

"And what they mean by that is, he has a need for immediate gratification. It is all about him."

Trump has repeatedly blasted book as fake, describing it as "full of lies.”

Haley on Sunday also pushed back on the claims made in the book.

“I am always amazed at the lengths people will go to lie for money and for power, this is like taking it to a whole new level," she added.
