President Donald Trump used a White House address to allege that China interfered in the 2020 US election and that American voting systems have serious security weaknesses. The claims, made three months before the midterm elections, matter because Democrats say they could undermine confidence in the vote, while China and previous US intelligence assessments reject them.

Trump said he had declassified hundreds of intelligence documents and alleged China obtained 220 million voter files across 18 states, although he presented no evidence that this altered voting systems or election results. A 2021 National Intelligence Council assessment said with high confidence that China did not interfere in the 2020 election; Beijing called the new allegations fabricated, and many released documents were heavily redacted.
