Glenn Kessler spent 15 years as the Washington Post fact-checker. He stepped aside recently and now writes at his Substack blog. For years, he has had the daunting task of counting Trump’s lies. Trump has the unparalleled ability to lie with great sincerity even when he knows he is lying.

He writes:

The hardest part about building a list of Donald Trump’s ten biggest lies in a year is the abundance of material.
When I ran The Fact Checker at The Washington Post, our team counted more than 30,000 false or misleading claims in his first term. That’s more than 20 erroneous claims a day. No one is keeping such a comprehensive list in his second term — it’s a thankless duty — but I’m sure he’s keeping the same pace.

Trump makes many false statements, big and small, and I tried to keep this accounting to substantive issues, both domestic and foreign. Even so, I found myself removing claims that others might consider worthy of inclusion.
For instance, he regularly claimed an executive order he issued on prescription drugs would “slash drug prices by 200 percent, 300 percent, 400 percent, 500 percent, 600 percent, 700 percent, 800 percent.” That’s a mathematical impossibility. A 100-percent cut would mean prices were zero. Trump is surrounded by so many lackeys that no one appears to have the heart to tell him.
Another arithmetic-challenged claim is Trump’s frequent boast that under his leadership the United States has secured nearly $20 trillion in new investments. That’s double the official White House count, which itself is a misleading brew of aspirations and vague promises, not actual investments. One clue this is bogus: Trump’s number is two-thirds of the annual gross domestic product of the United States.
Then there’s Trump’s claim that “Portland is burning to the ground,” apparently because he watched a Fox News report that included B-roll from 2020. This year, a few protesters outside an ICE facility have set some small fires, quickly extinguished. Again, why doesn’t his staff set him straight?
Another runner-up was Trump’s outrageous accusation that Erika McEntarfer, the commissioner of the Bureau of Labor Statistics, had manipulated jobs numbers. He fired her after job-growth estimates were revised downward — a common occurrence. “In my opinion, today’s Jobs Numbers were RIGGED in order to make the Republicans, and ME, look bad,” he fumed on social media, even though the estimates are derived from surveys conducted by professionals many rungs below the director. Trump never offered evidence for his claim.
Readers may have other nominations. Here’s my list for Trump’s biggest lies in 2025, in no particular order. Taken together, these falsehoods demonstrate how Trump governs — impulsively, defiantly, and often detached from reality.
“Instead of taxing our citizens to enrich other countries, we will tariff and tax foreign countries to enrich our citizens.”
Is it a lie if someone appears to firmly believe something? Trump may love tariffs but he’s been lying to himself as well as the American people about the impact. Every economist agrees that tariffs are a tax on consumers — not countries. Yet in his inaugural speech, Trump said the opposite. It is economic nonsense. Trump, of course, made this claim throughout the 2024 campaign (and in his first term), but it merits inclusion on the 2025 list because this lie had such real-world implications. Trump likely circumvented the Constitution by imposing such sweeping tariffs without congressional authorization, though the final verdict will come from the Supreme Court.
Throughout the year, Trump made many false claims about tariffs — “We’re taking in billions and billions of dollars. … We were losing $2 billion a day. … Now we’re making $3 billion a day” — and offering empty promises to use the “trillions” from tariffs to reduce taxes and pay down the national debt. The money raised from tariffs is not enough to reduce income taxes — and it is in fact another tax — and it won’t pay down the debt. That didn’t stop Trump from falsely claiming in November that tariffs would reduce the federal budget deficit by 25 percent.
By the end of the year, Trump offered $12 billion in aid to farmers hurt by his trade war with China — an unstated acknowledgment that tariffs do have costs for Americans.

“We identified and stopped $50 million being sent to Gaza to buy condoms for Hamas.”
On the face of it, this sounds idiotic, but Trump kept repeating it (and sometimes inflated the figure to $100 million) to justify terminating the U.S. Agency for International Development — an effort led by Elon Musk’s Department of Government Efficiency. But USAID, which distributed condoms to prevent the spread of sexually transmitted disease, spent less than $50,000 on condoms in the entire Middle East in a year — and nothing in Gaza.
In a striking example of the White House’s sloppy staff work, someone appears to have confused Gaza, the Palestinian enclave on the Mediterranean, with the Gaza province of Mozambique in Africa — and then USAID funding with Health and Human Services Department money given to the Elizabeth Glaser Pediatric Aids Foundation for HIV/AIDS prevention. It would be funny if it were not so sad.
Nevertheless, despite such fiction, USAID was dismantled, at great cost to the United States’ global reputation and with little impact on the $7-trillion federal budget. Though Trump in February claimed that DOGE had already saved as much as $500 billion, DOGE itself only tallied $214 billion by December. Of course, that’s also an exaggerated figure. When Politico scrubbed the data in August, it found the savings amounted to less than five percent of the claimed value. That’s because DOGE would count the ceiling value of contracts, which is far more than what the government has agreed to pay.

“You should have never started it. You could have made a deal.”
Trump said this in February about Ukrainian President Volodymyr Zelensky, who has, against the odds, managed to fend off a Russian assault on his country for nearly four years.
Trump, who for some inexplicable reason always tilts toward Russia, echoed the Russian position that it was pushed into the conflict. It’s akin to saying Japan was forced into attacking Pearl Harbor because the United States imposed a trade embargo in 1940, depriving Japan of oil. The trade embargo came after Japan’s provocative actions in the Pacific, such as the 1931 occupation of Manchuria following a Japanese-manufactured incident.
This comment is emblematic of a series of Trump’s lies about Ukraine — that Zelensky admitted U.S. aid is missing, that Zelensky has never said he has been grateful for American assistance, that the United States provided more aid than Europe, and so forth. Despite sometimes suggesting he was exasperated by Russia, Trump throughout the year has consistently favored Moscow over Kyiv in the conflict that, in the 2024 campaign, he claimed he would solve in 24 hours.

“We’ve ended weaponized government where, as an example, a sitting president is allowed to viciously prosecute his political opponent like me.”
Trump made this proclamation in his annual speech to a joint session of Congress, a clear example of a lie of commission. He and his allies already had fired career Justice Department and FBI employees who worked on the Jan. 6 cases or the Trump prosecutions, launched investigations into political groups and donors, and targeted law firms who worked on cases against him.
Soon, Trump ordered the indictments of former FBI director James Comey and New York Attorney General Letitia James, after firing the U.S. Attorney who decided the cases were weak. The cases rested on such shaky ground that they were soon dismissed. But they could be revived and Trump’s point was made — cross him and you will be in the crosshairs.
(For the record, there is no evidence that Joe Biden directed the Justice Department or local prosecutors to pursue the four criminal cases against Trump.)

“Just about everything is down. You know, this whole thing is, they use the word affordability. It’s a Democrat hoax.”
By year’s end, Trump’s approval rating had fallen sharply, largely because Americans perceived he was not focused on “affordability” — the rising cost of goods and services.
As usual, Trump thinks he’s doing great. In December he gave himself a score of “A-plus-plus-plus-plus-plus” for his handling of the economy. When asked by Laura Ingraham why Americans were anxious, he dismissed the concern: “I don’t know they are saying that. The polls are fake. We have the greatest economy we’ve ever had.” Even though grocery prices were up, Trump insisted they were down.
Instead, he lied that any problems faced by Americans were the legacy of Biden’s presidency, claiming that “we inherited from the last administration an economic catastrophe and an inflation nightmare.” In fact, Trump inherited an economy with relatively low unemployment, falling inflation and strong growth. The month before the November election, the Economist newspaper published a cover story declaring that the U.S. economy was “the envy of the world.” Taking office, Trump upended the economy — and sent prices higher — by imposing sweeping tariffs.

“Don’t take Tylenol. Fight like hell not to take it.”
Trump’s news conference in September claiming a link between Tylenol and autism was an appalling display of ignorance and hubris.
He falsely suggested autism rates were soaring — from 1 in 10,000 to 1 in 36 — when in fact the diagnosis of autism has increased because of better detection and expanded definitions. He seized on a disputed report to blame Tylenol, despite decades of research failing to find a causal link. He claimed nonsense that Amish don’t have autism because they refuse vaccinations. Surveys show many Amish vaccinate their children and that there is autism in the community. He cited a “rumor” that Cuba has no autism because the island can’t afford Tylenol. That curious claim was news to Cuba doctors. And then he told American women that they shouldn’t take Tylenol even if they suffer a fever — though fevers can be very harmful to fetuses. (Indeed, it may be fever, not Tylenol, that is linked to autism.)

“I’ve ended eight wars.”
No one can accuse Trump of modesty. In his desperate bid to be awarded the Nobel Peace Prize — Barack Obama won one, after all — Trump over the course of the year has added to his list of “wars” that he claimed he’s ended. But few of these were wars, Trump’s role was often tangential, and the resolution of the conflicts are likely temporary. Many of the pauses require careful follow-up to ensure implementation, and already some are falling back into bloodshed.
Yet that has not stopped Trump from claiming credit and even asserting “we’ve never had a president that solved one war, not one war.” That’s obviously false. Theodore Roosevelt won the Nobel Peace Prize in 1906 for negotiating peace in the 1904-5 war between Russia and Japan, while Jimmy Carter negotiated the Camp David Accords between Israel and Egypt in 1978.
What’s on Trump’s list? Cambodia and Thailand (A border dispute keeps flaring up, and indeed restarted in December); Armenia and Azerbaijan (They signed a U.S.-brokered peace deal in August, with Trump hosting an Oval Office ceremony, but it must be ratified and Armenia needs to change its constitution); Israel and Iran (a ceasefire was declared after a 12-day conflict but the decades-long conflict continues); India and Pakistan (The long-running dispute over Kashmir continues, though a ceasefire was reached in May; Trump’s claim of credit has been rejected by India); Rwanda and the Democratic Republic of Congo (Fighting continues though a peace agreement was signed with U.S. involvement); Egypt and Ethiopia (This is a mystery entry on Trump’s list as the nonviolent dispute is over hydroelectric dam opened by Ethiopia); Serbia and Kosovo (Another mystery entry as tensions have never eased since Kosovo broke off in 2008); Hamas and Israel (Trump pushed Israel to finally agree to a ceasefire in the two-year war, a real accomplishment, though a final resolution to the conflict appears elusive).
As you can see, it’s inflated and rather crass, much like accepting a dubious “world peace award” from FIFA and renaming the U.S. Institute of Peace after himself after the administration fired the staff and destroyed it.

“Every boat that you see get blown up, we save 25,000 – on average – 25,000 lives.”
Trump has been under fire for the administration’s military strikes on alleged Venezuelan drug boats in international waters, and in defense he offered a nonsense figure. Dutifully, other administration officials have echoed the lie.
First of all, the administration had not provided evidence that the boats carried drugs. Trump asserts they were transporting fentanyl but that makes no sense since Venezuela mainly supplies cocaine to Europe. In three months, about 20 vessels have been hit by airstrikes, killing more than 80 people, so using Trump’s math that would mean 500,000 Americans lives supposedly were saved. Yet provisional federal data shows that the total number of U.S. overdose deaths was about 75,000 in the 12 months ending in April (the most recent period available).
In other words, Trump invented these numbers. (The “on average” is an effort at verisimilitude.) It’s not supposed to make sense — just sound good.

“These [Epstein] files were made up by Comey. They were made up by Obama. They were made up by Biden.”
One of the few issues Trump could neither spin nor shrug off centered on demands that his administration release the investigative files on convicted sex offender Jeffrey Epstein, a onetime friend from the 1990s with whom he later fell out. Trump had promised to release the files during the 2024 campaign, but then the Justice Department refused to do so. Pressure built in Congress for passage of a law to force the files’ release, and in July Trump lashed out, claiming the files were all made up by Democrats, name-checking former FBI director James Comey, Obama and Biden.
This claim is simply nuts. The files represent investigative evidence, so nothing was invented. Neither Obama nor Biden were in office when the FBI investigated Epstein — that happened under George W. Bush in 2007-2008 and Trump in 2018 — while Comey wasn’t even in government at the time. Epstein, who molested hundreds of girls, at first received a sweetheart deal that minimized his crimes, and then the case was reopened under Trump after a Miami Herald investigation. He was found dead in his prison cell in 2019 while awaiting trial, an apparent suicide.
Trump’s instinct is to deflect problems onto his opponents, but he wasn’t successful in this instance. Congress passed the law, requiring the files be released by Dec. 19. The Justice Department has indicated it won’t meet the deadline.

“It won’t interfere with the current building. It will be near it but not touching it. And pays total respect to the existing building.”
This was Trump in July, speaking about his plans to add a ballroom to the White House complex.
Then, suddenly, in October, wrecking crews ripped down the entire East Wing of the White House. Trump was unrepentant about the fierce public outcry, dismissing the East Wing as “common brick, little tiny windows, it looked like hell.” (The White House skipped the requirement to submit its demolition plans, claiming the National Capital Planning Commission has no jurisdiction over demolition.)
In July, Trump had said the ballroom would hold 600 to 700 people and cost $200 million; now the plans call for about 1,000 people, the budget ballooned to more than $300 million, and the architect was replaced because he objected to Trump’s grandiose ambitions. The resulting 90,000-square-foot building will overshadow the existing 55,000-square-foot White House structure.
Is there any lie more emblematic of how Trump has approached his second term? He forges ahead, destroying any obstacles in his path, including the truth, while paying little heed to what Americans might think.
