The Texas Republican's measure would amend the National Voter Registration Act to "permit states to require proof of citizenship for registration to vote in elections for federal office," Politico reported.
"Today #SCOTUS ruled federal 'Motor Voter' law preempts AZ proof-of-citizenship requirement for voter registration," Cruz posted on Twitter. "I'll file amendment to immigration bill that permits states to require ID before registering voters & close this hole in fed statutory law."
He filed the amendment about 2 hours later without any initial co-sponsors, the Washington publication said.
