On Thursday, the Washington Post published a remarkable story on its front page revealing a recent spike in the number of “false and misleading claims” made by President Trump. In his first year as President, Trump made 2,140 false claims, according to the Post. In just the last six months, he has nearly doubled that total to 4,229. In June and July, he averaged sixteen false claims a day. On July 5th, the Post found what appears to be Trump’s most untruthful day yet: seventy-six per cent of the ninety-eight factual assertions he made in a campaign-style rally in Great Falls, Montana, were “false, misleading or unsupported by evidence.” Trump’s rallies have become the signature events of his Presidency, and it is there that the President most often plays fast and loose with the facts, in service to his political priorities and to telling his fervent supporters what they want and expect to hear from him. At another rally this week, in Tampa, Trump made thirty-five false and misleading claims, on subjects ranging from trade with China to the size of his tax cut.

These astonishing statistics were compiled by a small team overseen by Glenn Kessler, the editor and chief writer of the Post’s Fact Checker column, who for much of the last decade has been truth-squadding politicians and doling out Pinocchios for their exaggerations, misrepresentations, distortions, and otherwise false claims. At this point, Kessler practically has a Ph.D. in the anthropology of the Washington lie, a long and storied art form which has always had skilled practitioners of both parties. But Trump has challenged the Fact Checker, Kessler told me over coffee this week, in ways that have tested the very premise of the column. The President, for example, has a habit of repeating the same falsehoods over and over again, especially as they concern his core political causes, such as trade or immigration or getting European allies to contribute more to NATO. What should Kessler do, he often asks himself, when Trump repeats a four-Pinocchio whopper? Since taking office, the Post fact-checking team found, Trump has repeated close to a hundred and fifty untruths at least three times. Kessler has instated a Trump-specific database in response. Initially, the Post planned to compile the database of Trump’s misrepresentations as part of a project for his first hundred days in office. But the numbers kept piling up; now, Kessler told me, he is committed to keeping it up for Trump’s full term, documenting every “untruth” (per Post policy, he does not use the label “lies” even for the most egregious Presidential whoppers). “We’re kind of doing it for history,” he said.

History books will likely declare the last few months a turning point in the Trump Presidency, and Kessler’s laborious work gives us metrics that confirm what is becoming more and more apparent: the recent wave of misstatements is both a reflection of Trump’s increasingly unbound Presidency and a signal attribute of it. The upsurge provides empirical evidence that Trump, in recent months, has felt more confident running his White House as he pleases, keeping his own counsel, and saying and doing what he wants when he wants to. The fact that Trump, while historically unpopular with the American public as a whole, has retained the loyalty of more than eighty per cent of Republicans—the group at which his lies seem to be aimed—means we are in for much more, as a midterm election approaches that may determine whether Trump is impeached by a newly Democratic Congress. At this point, the falsehoods are as much a part of his political identity as his floppy orange hair and the “Make America Great Again” slogan. The untruths, Kessler told me, are Trump’s political “secret sauce.”

That appears to be the case for others on Trump’s team as well. As Kessler and I talked, the White House press secretary, Sarah Huckabee Sanders, presided at one of her increasingly rare press briefings. (Another metric to consider: Sanders gave three briefings in all of July, while previous Administrations conducted them daily.) In the briefing, Sanders repeated a number of false claims, including one that Kessler had previously debunked, that reporters put out “leaked” information that caused Osama bin Laden to stop using his satellite phone and slowed the hunt for the Al Qaeda leader before the 9/11 attacks. Kessler heard about Sanders’s false claim as we were leaving and retweeted his old article. “Kind of amazed but not surprised,” he wrote on Twitter, that the White House press secretary “would cite uninformed reporting that appeared BEFORE I debunked this fable in 2005.”

To me, the striking thing was that Sanders’s false claim was part of her prepared remarks; she read them from a piece of paper in the midst of a press-bashing jeremiad about the evils of what Trump calls “fake news.” A day later, she made her personal view of the press clear. Asked repeatedly Thursday whether she endorses Trump’s oft-stated line that the media are the “enemies of the people,” Sanders refused to reject Trump’s characterization. “I’m here to speak on behalf of the President,” she said. “He’s made his comments clear.” The White House assault on the truth is not an accident—it is intentional.

Other metrics make clear the significant changes in Trump’s approach to the Presidency in recent months, as he has become more confident, less willing to tolerate advisers who challenge him, and increasingly obsessed with the threats to his Presidency posed by the ongoing special-counsel investigation. One is the epic turnover rate of Trump’s White House staff, which as of June already stood at the unprecedented level of sixty-one per cent among the President’s top advisers.

All the departures from Trump’s troubled West Wing have created a new set of dilemmas for the political world, which normally welcomes even the most controversial White House advisers into a comfortable post-power life of high-paid lobbying or consulting jobs, speaking tours, and cushy think-tank or academic gigs. Will those smooth transitions continue? Should they?

At Harvard, an uproar greeted the decision of the Kennedy School of Government to name Trump’s first press secretary, Sean Spicer, a visiting fellow, although, at Stanford, the recent decision by the Hoover Institution to name H. R. McMaster, Trump’s fired national-security adviser, a senior fellow prompted little protest. After Marc Short quit the Trump White House last month, he headed toward such a life as well. Short, a veteran conservative political operative, worked to oppose Trump’s nomination in the 2016 Republican primaries while on the payroll of the big G.O.P. donors the Koch brothers. Nonetheless, he went on to serve as Trump’s chief legislative liaison and congressional vote-counter. Short also often defended Trump on television. After leaving the White House, he landed a paid gig as a CNN commentator (the network where I am also a contributor), a partnership at a Washington consulting firm, and a fellowship at the University of Virginia’s Miller Center.

Short’s hiring at U.V.A. has set off a major controversy in Charlottesville, which will soon mark the one-year anniversary of the violence-scarred white supremacist march that prompted one of Trump’s most controversial statements as President, his declaration that there were bad people and violence “on both sides.” Unlike others in the Administration, Short never publicly objected to Trump’s Charlottesville remarks (though he told me the White House had not handled it “the way we should have.”) In the two weeks since Short’s hiring, thousands of U.V.A. students and professors have signed a petition opposing it, although the Miller Center and U.V.A.’s new president are sticking by him. William Antholis, the Miller Center’s director, told me he believed Short’s appointment was about “understanding the Trump Presidency and engaging in civil dialogue about it, including with somebody who knows it and understands it well, but in my view is still within the legitimate bands of political disagreement.” But Antholis acknowledged that, for many opponents of Trump, this is not a Presidency to be treated like those that preceded it. “The challenge we face is similar to the one all media organizations face: the Trump Presidency and the Congress represent forty per cent of the American people and eighty to ninety per cent of the Republican Party, so can you just completely say that is an illegitimate viewpoint and that anybody complicit in it is by association guilty? Where do you draw the bands of complicity?”
