The Department of Homeland Security (DHS) acknowledged in court filings on Monday that "potential inaccuracies were identified" in the database it is using to look for illegal foreign voters—and that its investigation process carries the risk that "in rare circumstances U.S. citizens might be incorrectly identified as aliens."
The department's lawyers told the court that "there are various safeguards in place to prevent mistakenly contacting a U.S. citizen" for interrogation, but its filings do not say what happens to U.S. citizens placed on a watchlist.
