David Stern spoke out against plans by New Jersey to allow sports betting in the state.

The NBA, MLB, NFL, NHL and NCAA have an ongoing legal battle with the state in regards to the issue.

"The one thing I'm certain of is New Jersey has no idea what it's doing and doesn't care because all it's interested in is making a buck or two, and they don't care that it's at our potential loss," Stern said.

"And wholly apart from the fact that a governor, who's a former U.S. Attorney, has chosen to attack a federal law which causes me pause for completely different reasons since I've at times sworn to similar oaths about upholding the law of the United States," Stern said.
