The centerpiece election legislation from congressional Republicans would require voters to prove their citizenship when registering.

The nation’s cybersecurity agency has played a critical role in helping states shore up the defenses of their voting systems, but its election mission appears uncertain amid sustained criticism from Republicans and key figures in the Trump administration.

Republicans made claims about illegal voting by noncitizens a centerpiece of their 2024 campaign messaging.

WASHINGTON – The Supreme Court on Monday rejected an appeal from Kansas that sought to revive a law requiring proof of citizenship to register to vote. The law was championed by former Kansas Secretary of State Kris Kobach, who led President Donald Trump’s now-defunct voter fraud commission. Kansas Secretary of State Scott Schwab, who supported the law when he was in the state legislature, pursued the Supreme Court appeal over the objection of Kansas Gov. Circuit Court of Appeals declared the law unconstitutional in April, affirming a trial court ruling. Justice Neil Gorsuch, who used to be a 10th circuit judge, sat out the Supreme Court's consideration of the case.
