“The president is the CEO of the country,” Haley told ABC News Chief Anchor George Stephanopoulos on “This Week” Sunday. “He can hire and fire anyone he wants.”

Stephanopoulos asked Haley if she found herself having to explain to foreign diplomats Trump’s domestic policy decisions, including his surprise choice to fire the FBI director, noting that a fellow U.S. ambassador, Dana Shell Smith in Qatar, tweeted last week that her job was becoming “increasingly difficult.”

Haley demurred at that suggestion, saying that no one in her job at the U.N. had asked her about Trump’s move.

She added that she believes the criticism of Trump stems from discomfort with his propensity to act on his decisions.
