The Justice Department is suing Texas over new voting restrictions that the federal government says will disenfranchise eligible voters and violate federal voting rights law.

The lawsuit filed Thursday in federal court in San Antonio challenges the law known as SB1 passed earlier this year to overhaul election procedures in the state.

The law, which bans 24-hour and drive-thru voting, imposes new hurdles on mail-in ballots and empowers partisan poll watchers, was signed by Texas’ Republican Gov. Greg Abbott in September.

The Justice Department lawsuit said the law illegally restricts voters’ rights by requiring rejection of mail ballots “for immaterial errors and omissions.” The law also harms the rights of voters with limited English proficiency, military members deployed away from home and voters overseas, the Justice Department alleged.

“Before SB 1, the State of Texas already imposed some of the strictest limitations in the nation on the right of certain citizens to voting assistance. SB 1 further, and impermissibly, restricts the core right to meaningful assistance in the voting booth,” the Justice Department said.

Earlier this year, the DOJ sued Georgia over its new voting law, similarly arguing a violation of federal voting rights law.

The Texas law passed following a contentious debate in which some Democrats left the state to try to prevent its approval. It was among a spate of similar laws in Republican-run states aimed in response to false claims of widespread voter fraud in the 2020 election.

“It does make it easier than ever before for anybody to go cast a ballot. It does also, however, make sure it is harder than ever for people to cheat at the ballot box,” Abbott said when he signed the law.

The lawsuit is the latest legal fight between the Biden Justice Department and Texas, which are battling in court over abortion rights, immigration enforcement and vaccine mandates.

“Finally, a Justice Department that fights for justice. Texas is torpedoing American democracy and our constitutional right to vote. We are encouraged to see the DOJ pushing back,” NAACP President Derrick Johnson said in a statement to CNN about the Texas lawsuit.

President Joe Biden said during a CNN town hall in late October that the US is experiencing “the greatest assault on voting rights in the history of the United States – for real – since the Civil War.” But the President said that pushing his massive Build Back Better plan has prohibited him from putting a major focus on voting rights, while promising to focus on the issue once his agenda is passed.

Biden also signaled he would be willing to fundamentally alter or completely get rid of the filibuster, which has effectively been used as a tool to block voting rights legislation on a federal level. He had previously supported preserving the rule.

Senate Republicans blocked the John Lewis Voting Rights Act on Wednesday from advancing when the Senate took a procedural vote on whether to open debate on the legislation. The bill which would fight voter suppression and restore key parts of the landmark Voting Rights Act, originally passed in 1965, failed in 50 to 49 vote. GOP Sen. Lisa Murkowski of Alaska was the only Republican to vote along with Democrats.

Other changes

The law introduced new mandates requiring Texans who vote by mail to provide either their driver’s license number or the last four digits of their Social Security number twice: once on their absentee ballot application forms and once on the envelope in which they return their ballots.

Those numbers will then be matched against voters’ records to confirm they are who they say they are – a change from the current signature matching process.

Under the law, the Texas secretary of state’s office is required to check monthly to make sure no one is on the state’s voter rolls who said they were not a citizen when obtaining or renewing their driver’s license or ID card.

It also makes it a felony for a public official to send someone a mail-in ballot application the person did not request, or to pre-fill any part of any mail-in ballot application they are sending to someone.
