US President Donald Trump fired top cybersecurity official Chris Krebs in a message on Twitter, accusing him without evidence of making a "highly inaccurate" statement affirming the November 3 election was secure and rejecting claims of fraud.
Trump has made debunked allegations that the election was"rigged" and refused to concede to President-elect Joe Biden. His campaign has filed a flurry of lawsuits in battleground states, although election officials in both parties have said they see no evidence of serious irregularities.
Krebs' work in protecting the election from hackers and combating disinformation about the vote won praise from lawmakers of both parties as well as state and election officials around the country.
Trump said on Twitter that Krebs had assured people in a"highly inaccurate" statement that the election had been secure when there were "massive improprieties and fraud - including dead people voting, Poll Watchers not allowed into polling locations," and voting machine errors that flipped votes from Trump to Biden.
Dozens of election security experts on Monday said claims of major hacks were unsubstantiated and absurd.
He angered the White House over a website run by the agency dubbed "Rumor Control," which debunks misinformation about the election,.
Matthew Travis, Krebs' deputy, resigned on Tuesday.Executive director Brandon Wales is expected to take over.
