President Donald Trump's decision to endorse Republican Sen. John Cornyn in the Texas Senate race may hinge on the passage of the SAVE America Act, a bill that would impose stricter voting requirements. The bill, which requires 60 votes to reach Trump's desk, is stalled in the Senate and requires photo identification and proof of U.S. citizenship to register to vote. Despite this uncertainty, both Cornyn and Texas Attorney General Ken Paxton have expressed their support for the bill. The South Dakota Republican majority leader, John Thune, expressed concern that the bill's passage might now be contingent on passing the bill, but cautioned that it is not guaranteed.
