Lt. Gov. Dan Patrick is looking into a lottery store that sold an $83-million ticket, calling into question courier services.

Lottery courier companies operating in Texas have been criticized by some lawmakers, saying they could open the door to money laundering.

The Winners Corner store in Austin has sold multiple winning lottery tickets. Texas Lt. Gov. Dan Patrick investigated the store in person.
