As President Trump continues to make unfounded claims of widespread election fraud, 59 of the world’s foremost experts on electronic voting are hitting back, saying that recent allegations of actual voting machine hacking “have been unsubstantiated or are technically incoherent.”

Monday’s letter came after almost two weeks of baseless and unfounded claims from Trump and some of his supporters that this month’s presidential election had been “rigged” in favor of President-elect Joe Biden. On Thursday, Trump started a new round of disinformation when he took to Twitter to say that polling machines made by Dominion Voting deleted 2.7 million Trump votes around the country.
