He noted from an article: "The NVRA does not require proof of U.S. citizenship for people to register to vote, only that potential voters fill out a form and attest under penalty of perjury that they are citizens. A federal voting law passed in 2002 also required applicants to provide a unique identification number to register, like a driver's license or Social Security number, which election officials say effectively serves as a citizenship check since both of those forms of ID involve the government checking whether someone is a citizen or not."
In fact, non-citizens are REQUIRED to have a SSN in order to work here. (ssa.gov). The Washington Examiner also reports millions of illegal aliens have SSNs. Using basic logic - something the left is poor at - it's obvious there are many, many non-citizens voting in our elections.
