The Senators wrote, in part: "The attached Disclosure confirms that the Department and USCIS leadership have abruptly diverted FDNS from its mission and directed personnel to an 'Unlawful Voter Initiative' using highly questionable data and methods to identify purported unlawful voters. DHS and USCIS training materials admit these investigations will include U.S. citizens, some of whom will have federal law enforcement records created about them based on unreliable data and rushed reviews by officers held to quotas. This initiative is placing FDNS employees in an impossible position. They are being directed to take actions in the weeks before the election that this whistleblower believes are against the law and Department policy, and which will harm Americans."
