MGM Resorts International was under investigation after the underage son of basketball great Michael Jordan bragged on Twitter about partying at a Las Vegas Strip nightclub, Nevada gambling regulators said yesterday.

Officials were examining whether the casino operator violated laws prohibiting drinking or gambling by minors, Nevada Gaming Control Board enforcement chief Jerry Markling said.

Jordan's 19-year-old son Marcus Jordan tweeted Aug. 20 about spending $35,000 at Haze at Aria Resort & Casino.

"Last night was stupid . . . 35K at Haze," the University of Central Florida sophomore guard said. "Totals 50K something the whole day."

Jordan told a Fox Sports website last week that the tweet was a mistake and said he had conversations with both his parents about it. "I didn't mean it the way it came across," he said. "My family and friends know the type of person I am."

Jordan was in Las Vegas for his dad's fantasy basketball camp with his brother, Jeffrey, and teammate A.J. Rompza.
