The Texas Lottery, one of the largest in the U.S., is facing mounting scrutiny from state leaders over how the winners of an $83 million jackpot this month and a $95 million prize in 2023 purchased their odds-defying tickets. Both are among the largest jackpots in the history of the Texas lottery.

AG Ken Paxton’s office joins two other investigations by state officials into the commission as one service suspends operations due to the agency’s ban.

The Texas Lottery Commission’s executive director said Monday he would move to ban couriers from buying lottery tickets after finding that state law bars the practice, an about-face from the agency’s yearslong claim it had no control over such third-party sales.
