John Kelly, the White House chief of staff, abruptly scrapped plans to travel with President Donald Trump on Wednesday so he could try to contain his boss’s fury and manage the fallout from new revelations about tensions between the president and Secretary of State Rex Tillerson, according to six senior administration officials.

Kelly summoned Tillerson, and their ally Defense Secretary James Mattis, to the White House, where the three of them huddled to discuss a path forward, according to three administration officials. The White House downplayed Kelly’s decision to stay in Washington, saying he did so to manage day-to-day operations.

Vice President Mike Pence, meanwhile, was fuming in Phoenix, where he was traveling, seven officials told NBC News. He and Tillerson spoke on the phone before the secretary’s public appearance on Wednesday morning.

Pence was incensed upon learning from the NBC report that Tillerson’s top spokesman had said he once privately questioned the value of Nikki Haley, the U.S. ambassador to the United Nations. Officials said the spokesman, R.C. Hammond, fabricated an anecdote that Pence had asked Tillerson in a meeting whether Haley, who is seen as a possible successor if Tillerson, is helpful or harmful to the administration.
