US election officials have said the 2020 White House vote was the “most secure in American history”, rejecting President Donald Trump’s fraud claims.
“There is no evidence that any voting system deleted or lost votes, changed votes, or was in any way compromised,” a committee announced.
They spoke out after Mr Trump claimed without proof that 2.7 million votes for him had been “deleted”.
He has yet to concede to the president-elect, Democrat Joe Biden.
The result of the 3 November election was projected by all the major US TV networks last weekend.
Mr Biden is now projected to have won Arizona, extending his lead by 11 electoral college votes to a total of 290, with Mr Trump on 217. It is the first time the state has voted Democrat since 1996.
Mr Trump has launched a flurry of legal challenges in key states and levelled unsubstantiated allegations of widespread electoral fraud.
In another development, a group of more than 150 former national security officials has warned that delaying the transition posed “a serious risk to national security”.
In a letter, they urged the General Services Administration – the government agency tasked with beginning the transition process – to officially recognise Joe Biden and his running mate Kamala Harris so that they could access “pressing national security issues”.
Meanwhile, China has finally extended its congratulations to Mr Biden and Ms Harris after days of silence. “We respect the choice of the American people,” a foreign ministry spokesman said. Russia has said it wants to wait for an “official result”.
The announcement from US election officials marks the most direct rebuttal from federal and state officials of President Trump’s unsubstantiated claims of election fraud.
Thursday’s joint statement was released by the Election Infrastructure Government Co-ordinating Council – which is made up of senior officials from the Department of Homeland Security and the US Election Assistance Commission as well as state-level officials who oversee elections and representatives of the voting machine industry.
“The November 3rd election was the most secure in American history. Right now, across the country, election officials are reviewing and double checking the entire election process prior to finalizing the result,” the group said.
“While we know there are many unfounded claims and opportunities for misinformation about the process of our elections, we can assure you we have the utmost confidence in the security and integrity of our elections, and you should too,” it added, without naming Mr Trump directly.
“When you have questions, turn to elections officials as trusted voices as they administer elections.”
The statement was posted to the website of the Cybersecurity and Infrastructure Security Agency (Cisa), which is part of the Department of Homeland Security.
The head of Cisa, Christopher Krebs, has reportedly incurred the White House’s displeasure over a Cisa website called Rumor Control, which debunks election misinformation.
On Thursday, Mr Krebs shared a post by an election law expert that said: “Please don’t retweet wild and baseless claims about voting machines, even if they’re made by the president.”
Cisa assistant director Bryan Ware stepped down on Thursday. The White House had asked for his resignation earlier this week, Reuters reports. Mr Krebs expects to be fired, the news agency adds.
Hours before the statement was released, Mr Trump tweeted that voting software used in 28 states had deleted millions of votes for him, but presented no evidence for the stunning claim, which appeared to originate from the obscure TV network One America News and was flagged by Twitter.
The claim was linked to the miscounting of votes in one Republican-leaning Michigan county. Unofficial results initially favoured Mr Biden but were later corrected in President Trump’s favour. State election officials acknowledged what had happened, saying human error was to blame, rather than a software malfunction.
