A federal court has blocked the controversial voter ID law in Texas, saying it discriminates against people of color. The law requires voters to show their photo identification at the polls, and Texas had hoped to implement it before the November election. But on Thursday, a three-judge panel said Texas had failed to prove the law won’t harm the voting rights of ethnic minorities. The Justice Department blocked the law earlier this year, warning it stood to disenfranchise at least 600,000 voters, a disproportionate number of which are Latinos and other minorities. Texas says it plans to appeal Thursday’s ruling to the Supreme Court.
