If Your Time is short

  • Trump has used the word “hoax” hundreds of times as president, most often in reference to the Mueller report and his recent impeachment.

  • Recent TV ads have attacked Trump for using the word in the context of the coronavirus.

  • Experts in political science said repetition of a simple word like “hoax” is a way for Trump to portray himself as a victim and mobilize support for his political causes.

President Donald Trump has been tossing around the word "hoax" since before he won the White House in 2016. Now, that favorite term might be coming back to bite him.

Joe Biden and liberal super PACs bolstering his 2020 presidential campaign are using Trump’s own words against him in a flurry of TV and digital ads.

One recent spot from Priorities USA juxtaposed early quotes from Trump downplaying the spread of the novel coronavirus with a graph tracing the exponential growth of U.S. cases.

The ad, like a similar Biden ad before it, featured audio from a February campaign rally of Trump saying the word "hoax" while talking about the coronavirus.

That edit infuriated the Trump campaign, which sent a cease and desist letter to TV stations calling the ad "patently false, misleading, and deceptive." The campaign said the ad "stitched together fragments from multiple speeches" to give a misleading impression.

Trump’s comments at the rally were not particularly clear, however. After accusing Democrats of "politicizing the coronavirus," Trump blasted the 2016 Russia investigation and his impeachment in the House — both of which he has labeled a hoax — before briefly turning back to the virus.

"Think of it," he said. "And this is their new hoax."

The next day, Trump claimed he was referring to the Democrats’ criticism of his response to the coronavirus, rather than to COVID-19 itself. 

But for some Trump critics, Trump’s habitual use of the word in other instances made it hard to believe he wasn’t talking about the coronavirus.

"We don't trust his next-day clean-up attempt, and he has made many comments in that same vein," Biden campaign spokesman Andrew Bates told us when we fact-checked Biden’s ad.

Is Trump the president who cried hoax? His use of the word while talking about the virus that’s now infected more than 160,000 Americans certainly brought him unwanted attention. 

So, we decided to talk to experts about the word and why Trump uses it.

What Trump has called a hoax, and why

Experts in political science told us that Trump uses the word — and others like it — to portray himself as a victim of injustices and inspire his supporters to fight for him and trust his word.

"Trump is trying to undermine the trustworthiness of any source but himself," said Margaret Levi, professor of political science at Stanford University. "The point is to make himself the only credible authority, to be fully trusted as a ‘war-time’ president."

Trump has been throwing around the word since before he took office. According to Twitter and, the interactive website that tracks Trump’s public comments and tweets, Trump has used the word more than 600 times dating back to his days as a celebrity.

Many of his earliest uses on Twitter were in reference to global warming, which he frequently bashed as an "expensive hoax." As Trump’s 2016 political opponents pointed out, he once claimed the concept was made up by the Chinese; he’s since said he was joking.

Trump’s reliance on the word took off once he became president. For years, Trump denounced former special counsel Robert Mueller’s investigation of Russian interference in the 2016 election as a "hoax," all the while offering no credible evidence in support of his claim.

The word has stuck with Trump’s supporters and become part of his brand, making it more effective, said Cas Mudde, professor of international affairs at the University of Georgia.

"As many of his supporters believe him on, for example, Russian interference in the 2016 elections being a ‘hoax,’ describing other events with exactly the same term reminds them of the Mueller investigation and strengthens his claim on the new event," Mudde said.

A 2019 report from the Justice Department’s inspector general found that the Russia probe was justified. But Trump has still used the word dozens of times to brand Mueller’s work and the notion that his campaign colluded with Russia, according to

Trump took aim at Mueller’s investigation as recently as March 30, saying in an interview with Fox News that "the whole thing turned out to be a hoax." He has also dismissed warnings from the intelligence community about pro-Trump Russian meddling in 2020 as "Hoax number 7."

Repetition like that can be especially powerful, experts told us. 

"The word serves as a symbol or signifier that conveys a complicated set of circumstances in a simple way," said Lynn Vavreck, professor of American politics and public policy at UCLA.

That may explain why Trump invoked it again to condemn the House’s impeachment of him for his efforts to pressure Ukrainian President Volodymyr Zelensky into announcing an investigation of Joe Biden, his son Hunter and a debunked conspiracy related to the 2016 election.

In addition to calling his impeachment a "witch hunt," a "scam" and a "coup," Trump has repeatedly used "hoax" to describe the impeachment process and any accusations of presidential misconduct, including most recently during a March 31 White House press conference on the coronavirus. 

He has also used the word on Twitter to dispute news reports and discredit sexual assault allegations made against him, among other things.

Vavreck said Trump’s use of the word creates a feeling of solidarity between him and his supporters and activates an "us versus them" framework.

"Trump uses it to suggest to his supporters that someone is trying to fool them and they should beware," she said. "It also suggests that he, along with them, is a victim of the effort."

But there’s no fooling when it comes to the coronavirus, which has shut down cities and killed thousands of Americans. Regardless of what he meant, Trump’s mention of a "hoax" while talking about COVID-19 carried different risks than his usual weaponization of the term. 

Matthew Kavanagh, assistant professor of global health at Georgetown University, said Trump’s use of the word "hoax" in the context of the coronavirus was "very dangerous" given his history of challenging the veracity of the media and the trustworthiness of public officials.

That’s because public trust is crucial for fighting outbreaks of disease like the coronavirus, Kavanagh said. "Success against the pandemic depends on people believing and complying with the advice of public health officials as seen through the media," he said. 

Kavanagh noted that a poll conducted in mid March found fewer Republicans taking precautions related to the coronavirus than Democrats, and that some Republican governors have been slower to take statewide actions to mitigate the spread.

"I worry that President Trump's early statements encouraged local Republican-led governments not to take the threat seriously," Kavanagh said.
