Lt. Gov. Dan Patrick is investigating the legality of lottery couriers after a winning $83.5M lottery ticket was sold at a North Austin store. That store has sold several winning tickets in the past couple of years.

Texas Lt. Gov. Dan Patrick says he is concerned about fairness and transparency after an $83.5 million-winning ticket was sold to a courier service that also owns the store where the ticket was bought.

On Thursday, the Texas Senate unanimously voted to ban lottery courier services, as allegations of money laundering and fraud prompted investigations from the Texas Rangers and the Attorney General's office.

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.

Lawmakers and state authorities are scrutinizing the Texas Lottery after online ticketing systems may have given an unfair advantage to winners of two multimillion-dollar jackpots. Why it matters: Attorney General Ken Paxton on Wednesday opened an investigation into two "suspicious and possibly unlawful" lotto wins by third-party courier services.

The Texas Lottery winnings being questioned have centered on the idea of bulk purchases of tickets through courier services.
