Glenn Kessler is the fact checker for The Washington Post. He describes what it is like to check the nation’s most notorious prevaricator.

Kessler writes:

In my 14 years as The Washington Post Fact Checker, nine have been devoted to dissecting and debunking claims made by Donald Trump. Indeed, no person has been fact-checked more often than Trump, as he has bested or outlasted foes — Hillary Clinton, Joe Biden and Kamala Harris — who drew their share of fact checks. And no other person has consistently earned Four Pinocchios — the badge of a committed liar — day after day, week after week.


I first covered Trump as a business reporter in the 1980s, so I was very familiar with his long history of exaggeration and bravado when he burst onto the political stage in 2015 (not counting his brief flirtation with the Reform Party in 2000). “Businessman Donald Trump is a fact checker’s dream … and nightmare,” I wrote in the fact check of his speech announcing that he would seek the presidency.


Now, he has convincingly won a second term via the electoral college and is even on track for the first time in three tries to win the popular vote. After his first two races, I wrote analyses that, in retrospect, misjudged the Trump phenomenon.

In 2016, I noted that “based only on anecdotal evidence — emails from readers — one reason that Trump’s false statements may have mattered little to his supporters is because he echoed things they already believed.” But I expressed hope that “now that Trump will assume the presidency, he may find that it is not in his interest to keep making factually unsupported questions.”

As an example, I noted that during the campaign he had claimed that the unemployment rate was 42 percent, rather than the 5 percent in official statistics. I suggested that he might find himself embarrassed to be contradicted by the official data once he took office.


I was wrong. He embraced the numbers as his own — and then bragged that he had created the greatest economy in American history, even though he had inherited it from Barack Obama.
When Trump was defeated in 2020, my analysis carried a headline that is embarrassing in retrospect: “Fact-checking in a post-Trump era.” I wrote that “his defeat by Democrat Joe Biden suggests that adherence to the facts does matter.”


The Fact Checker documented more than 30,000 false or misleading claims that Trump made during his presidency. Indeed, through that term, Trump was the first president since World War II to fail to ever win majority support in public opinion polls. A key reason was that relatively few Americans believed he was honest and trustworthy, an important metric in Gallup polls. Gallup has described this as “among his weakest personal characteristics.”

As evidence that Trump was hurt by falsehoods, I pointed to Biden’s narrow victories in Arizona and Georgia: “It’s quite possible that at least 9,000 people in Arizona and 5,000 in Georgia were upset enough at Trump’s continued false attacks on native sons Sen. John McCain (R) and Rep. John Lewis (D), even after they died, that they decided to support Biden over Trump.”

The essay appeared before Trump embarked on a months-long campaign to claim that Biden won only through election fraud — a lie debunked in court ruling after court ruling. The Jan. 6, 2021, attack on the Capitol, inspired by his rhetoric, appeared to be an indelible stain. Yet from 2020 on, Trump used his false claim to maintain his Republican support and build a base for his comeback.


In this election campaign, Trump once again resorted to false claims and sometimes outrageous lies, especially on immigration and the economy. He rode a wave of discontent about inflation — a problem in every industrialized country after the pandemic — to falsely claim that the economy was a disaster, despite relatively low unemployment, falling inflation and strong growth.


Last month, the Economist magazine published a cover story declaring that the U.S. economy was “the envy of the world.” Yet exit polls show that two-thirds of voters said the economy was in bad shape.


I do not write fact checks to influence the behavior of politicians; I write fact checks to inform voters. What voters — or politicians — do with the information in the fact checks is up to them.

Trump certainly benefits from an increasingly siloed information system — a world in which people can set their social media feeds or their television channel so they receive only information that confirms what they already believe. It’s perhaps not an accident that Trump’s rise in politics coincides with the rise of social media, which he adeptly used to first attract attention by elevating (false) questions about Obama’s birth certificate.


In this campaign, Trump made many promises that will be difficult to achieve, such as reducing the national debt and cutting energy prices in half. He also said he would reduce inflation, though that’s already been mostly achieved, and many economists say his plan to impose large tariffs on imported goods might spark inflation again.


No matter what happens, or how many fact checks are written, this time I won’t doubt his ability to convince his supporters that it’s all good news — or that the problem is the fault of someone else, facts notwithstanding.
