New Jersey’s quest to add sports betting in the state’s casinos and racetracks was delayed on Thursday at the state Assembly’s Regulatory Oversight and Gaming Committee, according to the Philadelphia Inquirer.

Senator Raymond Lesniak, who filed a lawsuit against the U.S. Justice Department in hopes of overturning the ban on sports wagering in all but four states, blames Harrah’s Entertainment for the stall tactic.

“I am really astonished at Harrah’s that they would continue to fight against New Jersey’s interests in order to protect their monopoly in Nevada on sports betting,” Lesniak told the Philadelphia newspaper. “They have no shame to openly fight against New Jersey and our needs for additional revenues for their own corporate greed.”

The Inquirer reports that Harrah’s Entertainment denied Lesniak’s accusation of any wrongdoing.

Marybel Batjer, a spokesperson for Harrah’s Entertainment, says any vote would be hasty until the Justice Department rules on Lesniak’s lawsuit to overturn the ban on sports betting.

The full Senate will vote on Assembly Bill 817, which would allow "in-person wagering at casinos on results of professional sports events, subject to voter approval," on June 21.

New Jersey casinos are experiencing difficult times. The Garden State casinos reported a nine percent drop in revenue from 2009.
