US President Donald Trump delivered a primetime speech on Thursday assailing the country's voting system and making several unverified claims about the electoral process.

He touted new declassified evidence about alleged Chinese interference in the 2020 election, dredged up an old case in Michigan about voter fraud and repeated a campaign trail favorite: that noncitizens are illegally registered to vote.

Trump has long cast doubt on the integrity of US elections, falsely claiming that the 2020 election was "stolen." Every relevant investigation, including dozens of court rulings, state-level audits and recounts all came to the same conclusion that Trump lost that election, by more than 7 million in the popular vote and 306-232 in the Electoral College.

"The November 3rd election was the most secure in American history," reada joint statement in 2020 from the government and industry bodies that oversee US election security. No evidence showed any voting system deleted, altered, or compromised votes, the statement added.
