Kansas cannot require people to prove their U.S. citizenship before they can vote, a federal judge says, ruling that the state's election law is unconstitutional. The judge sharply criticized Kansas Secretary of State Kris Kobach, who has based much of his political career on worries about voter fraud.

Chief District Judge Julie A. Robinson sanctioned Kobach — who led President Trump's voter fraud commission — by ordering him to take a legal class on the rules of evidence or procedure. Kobach represented his office and was the lead attorney in the case.
