Texas Attorney General Ken Paxton has launched an investigation of the Texas Lottery, including two “possibly unlawful” winnings that involved the purchase of bulk lottery tickets and the use of third-party courier services.

Two of the biggest lottery jackpots in Texas history are under widening investigations over claims that the winners may have benefitted from more than good luck.

The investigation into two controversial lottery jackpots in Texas had drummed up questions about the role of online ticketing firms known as lottery couriers in the state – and nationwide.
