NEW YORK — The Supreme Court lifted restrictions on a lower-court order from June that blocked a controversial federal voter database before November’s elections.

The Department of Homeland Security’s Systematic Alien Verification for Entitlements, or SAVE, program allows states to use a federal database to check voter eligibility. The lower court previously blocked the order due to privacy and accuracy concerns.

States are not required to use Save and the implications of it on the upcoming midterms are limited since most states don’t allow systematically purging voters from their rolls within 90 days of an election.

Since last year, the Trump administration has significantly expanded SAVE’s search abilities. 67 million registrations have been scanned so far, but critics are concerned that some registrants may be wrongly purged from the rolls. In Travis County, Tx., for example, at least 10% and up to 21% of 97 voters were flagged by SAVE as apparent noncitizens despite being citizens.

SAVE is one of many methods Trump has used to try to overhaul the way elections are run. Since the Constitution gives states and Congress the authority to set election rules, the president has limited power and many methods to control elections have been blocked by various courts.

Trump has continued to make noncitizen voting a major issue, despite it being rare and illegal. It is punishable as a felony with the potential for deportation.
