Republican Senator John Cornyn of Texas has reversed his position on the filibuster in order to pass President Trump’s SAVE America Act. The bill would require proof of citizenship for voter registration, require photo ID to cast a ballot, and require states to run voter rolls through a federal database kept by the Department of Homeland Security. Senator Cornyn is currently locked in a tight runoff election for his Senate seat with Texas Attorney General Ken Paxton and is seeking President Trump’s endorsement. The SAVE America Act was passed by the House, but Senate Democrats have vowed a filibuster to defeat the bill. Senate Majority Leader John Thune has refused to change the Senate’s rules to force a vote. On Wednesday, President Trump criticized Thune, saying, “He’s got to be a leader.” President Trump has vowed not to sign any other legislation until he has signed the SAVE America Act into law.
