Supreme Court allows Trump to use controversial database to check voter citizenship

Lawyers for the Trump administration have long argued that the system is lawful and necessary to prevent non-citizens from voting. A total of 27 states currently use the system to check voter citizenship.Critics, however, have pointed to a number of cases of the system already having led to mistakes.For example, officials in Travis County, Texas, found that of nearly 100 voters identified as non-citizens, at least 10% of them - and potentially more - were US citizens, according to US media reports.Since the state began checking its voter rolls with the Save system last year, only three non-citizen voters have been charged with illegally voting in Texas.Since returning to the White House in January last year, the Trump administration has sought to reform the US electoral system, a process that has included a bid - rejected by the Supreme Court - to reign in mail-in ballots.In 2024, for example, Texas Governor Greg Abbott announced that 1,930 people with a "voter history" had been removed from electoral rolls out of a total of nearly 18 million registered voters.The figures are far below the hundreds of thousands of non-citizen voters that Trump and the Department of Homeland Security have previously suggested were on voter rolls.
