The weekend began with a series of tweets from the president, and, like so many times before, several of them contained factually incorrect information. “The Failing @nytimes quotes ‘a senior White House official,’ who doesn’t exist,” one began. That official does, in fact, exist, and had provided a background briefing to hundreds of reporters on Thursday afternoon.

The Times responded with an article titled, “Trump Falsely Says Times Made Up Source in Report on Korea Summit Meeting.” Referencing that story and another tweet in which the president misrepresented his administration’s immigration policy, star White House reporter Maggie Haberman tweeted that “Trump told two demonstrable falsehoods this AM.” And that’s where another round of lie vs. falsehood started.

Trump told two demonstrable falsehoods this AM, one about his administration’s policy of separating undocumented immigrant kids inclu infants from their parents, which he tried to claim wasn’t his own policy. The other was falsely claiming his own aide didn’t give a bg briefing. — Maggie Haberman (@maggieNYT) May 26, 2018

Critics were appalled at Haberman’s deliberate use of a term that falls somewhere short of “lie,” and the argument consumed political media conversations on Twitter for much of the weekend. Some defended her—and the Times’s—judgment, but many (including actor John Cusack) impugned her credibility and accused her of being soft on the administration. I’ve argued in the past that we need to do away with euphemisms like “racially charged” when the president says something demonstrably racist. But the debate over when to use the L-word is nuanced. Trump provides steady stream of untrue statements, but are all of them lies?

The Toronto Star’s Daniel Dale elegantly laid out the difficulties in reporting on Trump’s falsehoods, noting that a lie involves intention. “In some cases, it’s safe to say Trump is intentionally trying to deceive. In other cases, it’s far less clear that he’s being wrong intentionally—because, with Donald Trump, you regularly can’t rule out the possibility that he is confused or ignorant,” Dale writes. “If we journalists are going to present ourselves as arbiters of truth, we have to stick to what we know is true. And that means not calling something a lie when we don’t have a reasonable certainty that Trump’s intention is deception.”

In the case of Trump’s claim about a source “who doesn’t exist,” journalists don’t know whether Trump was in the loop. “It is not clear whether the president was simply unaware of the actions of his own senior staff or if he knowingly ignored the truth,” Michael Shear wrote Saturday in the Times’s follow-up on the tweet.

Whatever label journalists choose for the president’s false statements, it’s obvious that Trump doesn’t always tell the truth. After all, the Times Opinion section, which has no compunction about calling them “lies,” kept a running tally of the falsehoods through the fall—it numbers in the hundreds. Whether each is intentional or unintentional, the more important job for the journalist is to provide context and evidence to refute them. Calling a statement a “deliberate falsehood” instead of a “lie” isn’t an attempt to excuse the behavior; it’s an attempt to accurately, if perhaps overcautiously, describe what’s going on.

Below, more on Trump’s tenuous relationship with the truth, and how journalists respond.

What’s in a name?: “We need to distinguish between a deflection, an exaggeration, and a straight-up lie,” CNN’s Brian Stelter said on Reliable Sources.

Case studies: While Dale argues that there are differences between lies and falsehoods, he writes that “making the right decision case-by-case means… that ‘lie’ should be used a lot more than almost every major US news outlet currently uses it.” He provides several examples on either side of the debate.
