Donald Trump on Sunday used his platform as president-elect to peddle a fringe conspiracy theory to justify his loss of the popular vote, claiming without evidence that millions of people voted illegally Nov. 8.

Trump’s tweets marked an unprecedented rebuke of the U.S. electoral system by a president-elect and met with immediate condemnation from voting experts and others. And they offered a troubling indication that Trump’s ascension to the highest political office in the United States may not alter his penchant for repeating unproven conspiracy theories perpetuated by the far right.


“In addition to winning the Electoral College in a landslide, I won the popular vote if you deduct the millions of people who voted illegally,” Trump wrote on Twitter. There is no evidence to support Trump’s claim and PolitiFact ruled it false.

Several hours later, he added more specifics, but again without any evidence: “Serious voter fraud in Virginia, New Hampshire and California — so why isn’t the media reporting on this? Serious bias — big problem!”

Election law experts quickly rejected Trump’s claims as far-fetched.

“There’s no reason to believe this is true,” said Rick Hasen, a professor specializing in election law at the University of California, Irvine. “The level of fraud in U.S. elections is quite low.”

Hasen added, “The problem of noncitizen voting is quite small — like we’re talking claims in the dozens, we’re not talking voting in the millions, or the thousands, or even the hundreds.”

David Becker, executive director of the Center for Election Innovation & Research and a former senior trial attorney in the Voting Section of the Department of Justice’s Civil Rights Division, agreed that widespread fraud was unlikely.

“We know historically that this almost never happens,” he said. “You’re more likely to get eaten by a shark that simultaneously gets hit by lightning than to find a noncitizen voting.”

A source close to the president-elect said he felt piqued by the Wisconsin recount demand of Green Party nominee Jill Stein, in which Hillary Clinton’s campaign has said it will participate, so he hit back. Even though he’s won and it shouldn’t matter, he isn’t letting it go, the source said.

Another adviser said Trump genuinely believes “that the Democratic establishment will try to steal” his victory. So his goal is to hold their feet to the fire.

The claims of voter fraud appear to have gained traction in conservative circle after Infowars, the conspiracy theory-laden website, published an article on Nov. 14 under the headline, “Report: 3 million votes in presidential election cast by illegal aliens.”

The story cites an analysis by Gregg Phillips, who claims to be the founder of a voting app named VoteStand and who was previously associated with Newt Gingrich’s Winning Our Future super PAC. Phillips has declined to provide any evidence to PolitiFact or reporters to support his assertions of fraud. But he tweeted Sunday evening that he would “release a comprehensive research study to the public, Attorney General [nominee Jeff] Sessions and all interested parties.”

Radio host Alex Jones, who runs Infowars, has faced criticism for promoting unsubstantiated — and often bizarre — conspiracy theories, including that the 2012 Sandy Hook Elementary School shooting, which resulted in the death of 20 children, is a hoax, and that Hillary Clinton is a “demon from Hell.”

Trump called Jones just days after the election to thank him for his support.

It’s not insignificant that Trump’s tweet also successfully shifted the media narrative away from negative stories about Trump’s many conflicts of interest. The New York Times published a front-page investigation into the conflicts on Sunday.

The president-elect has a long history of pushing debunked conspiracy theories, including the false claim that President Barack Obama wasn’t born in the United States and that the presidential election would be “rigged” by global elites to assure Hillary Clinton’s victory.

Hillary Clinton now leads the popular vote by about 2.2 million votes, though Trump won the Electoral College by beating Clinton in key battleground states like Pennsylvania, Ohio, Florida and Wisconsin.

Trump said Sunday on Twitter that he could have won the popular vote.

“It would have been much easier for me to win the so-called popular vote than the Electoral College in that I would only campaign in 3 or 4 ... states instead of the 15 states that I visited. I would have won even more easily and convincingly (but smaller states are forgotten)!” he wrote.

To bolster his claims, Trump has cited a 2014 blog post in The Washington Post by the authors of a disputed study that estimated that “6.4 percent of non-citizens voted in 2008 and 2.2 percent of non-citizens voted in 2010.” That study has faced intense scrutiny from election experts, with one analyst telling factcheck.org earlier this year, “Their finding is entirely due to measurement error."

Trump’s critics have argued that Clinton's popular vote victory raises questions about whether Trump has a solid mandate to govern.

Trump took to Twitter earlier Sunday, before making assertions of voter fraud, to bash the Clinton campaign’s decision to participate in the Green Party’s call for a recount. “The Green Party scam to fill up their coffers by asking for impossible recounts is now being joined by the badly defeated & demoralized Dems,” he tweeted Saturday.

While there is no evidence of such fraud, Clinton’s campaign agreed to participate “in order to ensure the process proceeds in a manner that is fair to all sides.”

The Obama administration has taken pains to bolster trust in the electoral system, with a senior administration official saying recently that the election results “accurately reflect the will of the American people.”

Presidential historians said Trump’s comments have little precedent.

“Trump is the first winning candidate to question the legitimacy of the process that gave him the White House,” said Timothy Naftali, a history professor at New York University.

Princeton historian Julian Zelizer noted that in 1876, both candidates for president — Samuel J. Tilden, the Democrat, and Rutherford B. Hayes, the Republican and eventual winner — claimed voter fraud. “But in that case, there was evidence of fraud and corruption in certain areas,” he wrote in an email.

“In this case, we see the victor making blanket accusation of fraud to delegitimize 2.5 million votes,” Zelizer said. “Given there is no evidence to support the claim, this is simply stunning and troubling as a sign as to what he will do as president.”
