Sen. Adam Schiff (D-CA) was adamant Sunday that requiring photo identification will “disenfranchise” voters from future elections.

Democratic lawmakers are opposing the Republican-led Safeguard American Voter Eligibility Act, which passed the House of Representatives last year and requires proof of citizenship to register to vote in federal elections. Schiff said he opposes a compromise of requiring photo ID to vote in United States elections, describing the SAVE Act as a “voter suppression law.”
