US President Donald Trump on Thursday released a cache of declassified documents as evidence to highlight the vulnerabilities in the American election systems.According to CNN, although the documents are newly declassified, they largely point out the fault lines which have already been known for years and election officials around the country have tried to address.None of the newly released documents, however, sustains Trump's claim that any previous election results — including the 2020 presidential contest that Trump lost — were manipulated by foreign interference or fraud in a way that would’ve changed the outcome.Claims made by TrumpMajor vulnerabilities with US voting machinesChina has obtained voter data on millions of AmericansSystemic voter registration fraud by Democrats in MichiganFar more non-citizens on voter rolls than known beforeA decent chunk of the documents rehash information that has already been public and widely understood in the US intelligence community.The documents are part of an attempt by the Trump administration to make the case that foreign countries are aggressively interfering with US elections. It’s worth noting that Trump has spent nearly a decade denying the unanimous conclusions from many of these same intelligence agencies that Russia meddled in the 2016 election.Vulnerabilities with US voting machinesA January 2020 National Intelligence Council report said Russia, China, Iran and North Korea had the capability to access and potentially manipulate US election data, including voter registration databases and pollbooks.However, the report said the decentralised nature of US elections would make it difficult for any breach to alter the overall outcome of a national election.The White House also cited documents claiming Venezuela tested methods to manipulate voting machines without detection. The allegations have previously been promoted by former Venezuelan intelligence chief Hugo "El Pollo" Carvajal.A declassified CIA memo, however, said US intelligence concluded in 2006 that neither Venezuela nor Smartmatic — the voting technology company at the centre of the claims — had the capability to manipulate elections outside Venezuela. Smartmatic has repeatedly denied the allegations.CNN noted that while vulnerabilities in US voting systems have been documented, there is no evidence that any foreign adversary has successfully exploited them to change election results.Claims on China accessing voter dataThe White House also alleged that China obtained more than 200 million US voter registration records between 2020 and 2024, including names, addresses, phone numbers, party affiliation and voting history.Officials claimed the data was obtained through hacking or other illicit means. However, the documents do not accuse China of altering voter records or changing election results.A separate intelligence report said Chinese hackers compromised voter databases in eight states, while also targeting healthcare systems, social media platforms and government agencies.A National Intelligence Council assessment from October 2020 concluded that China's election-related activities remained "low-level" and exploratory.China denied the allegations, saying it has never interfered in US elections.Claims on non-citizens on voter rollsThe White House also released Department of Homeland Security documents claiming at least 250,000 non-citizens were registered to vote in California, Pennsylvania, New Jersey and Nevada.However, the documents acknowledged the estimate relied on commercial databases, which are less reliable than government records.Using the federal SAVE database, DHS identified about 28,000 non-citizens registered to vote across 25 states but found no evidence of a significant increase in non-citizens casting ballots.Voting by non-citizens in federal elections is illegal, and election experts say such cases remain extremely rare, CNN reported.
