White House chief of staff Reince Priebus issued a stern warning at a recent senior staff meeting: Quit trying to secretly slip stuff to President Trump.

Just days earlier, K.T. McFarland, the deputy national security adviser, had given Trump a printout of two Time magazine covers. One, supposedly from the 1970s, warned of a coming ice age; the other, from 2008, about surviving global warming, according to four White House officials familiar with the matter.

Trump quickly got lathered up about the media’s hypocrisy. But there was a problem. The 1970s cover was fake, part of an Internet hoax that’s circulated for years. Staff chased down the truth and intervened before Trump tweeted or talked publicly about it.

The episode illustrates the impossible mission of managing a White House led by an impetuous president who has resisted structure and strictures his entire adult life.

While the information stream to past commanders-in-chief has been tightly monitored, Trump prefers an open Oval Office with a free flow of ideas and inputs from both official and unofficial channels. And he often does not differentiate between the two. Aides sometimes slip him stories to press their advantage on policy; other times they do so to gain an edge in the seemingly endless Game of Thrones inside the West Wing.

The consequences can be tremendous, according to a half-dozen White House officials and others with direct interactions with the president. A news story tucked into Trump’s hands at the right moment can torpedo an appointment or redirect the president’s entire agenda. Current and former Trump officials say Trump can react volcanically to negative press clips, especially those with damaging leaks, becoming engrossed in finding out where they originated.

That is what happened in late February when someone mischievously gave the president a printed copy of an article from GotNews.com, the website of Internet provocateur Charles C. Johnson, which accused deputy chief of staff Katie Walsh of being “the source behind a bunch of leaks” in the White House.

No matter that Johnson had been permanently banned from Twitter for harassment or that he offered no concrete evidence or that he’s lobbed false accusations in the past and recanted them. Trump read the article and began asking staff about Walsh. Johnson told POLITICO that he tracks the IP addresses of visitors to his website and added: “I can tell you unequivocally that the story was shared all around the White House.”

White House chief strategist Steve Bannon defended Walsh, who has since left the administration to advise a pro-Trump group, in a statement to POLITICO: “Katie was a key member of the team and is a trusted friend and ally of the White House. No one in the White House took that article seriously.” Walsh declined to comment.

But the smear of one of Priebus’ closest allies – Walsh was his chief of staff at the Republican National Committee – vaulted from an obscure web posting to the topic of heated conversation in the West Wing, setting off mini internal investigations into who had backstabbed Walsh.

When Trump bellows about this or that story, his aides often scramble…
