Massachusetts gambling regulators want to know why Steve Wynn and Wynn Resorts failed to disclose a $7.5 million settlement when they were applying for a state license in 2013.
The settlement will be a primary part of the investigation as it moves forward, investigators said at a meeting Wednesday.
The Massachusetts Gaming Commission announced Sunday that it's reviewing the license it issued for Wynn Boston Harbor, a $2.1 billion casino and hotel project set to open in 2019.
The commission could ultimately decide to alter, suspend or revoke the license as a result.
