Alabama lawmakers continue to work privately on legislation that would authorize a lottery, casinos, and sports betting if it is approved by voters.

The Alabama Senate Tourism Committee was scheduled to meet at 2 p.m. Tuesday to discuss two gambling bills that passed the House three weeks ago and changes to those bills.

One is a constitutional amendment that would require voter approval.

The committee chair, Sen. Randy Price, R-Opelika, told a packed committee room that the meeting was on hold and would resume upon his call as chair, probably later in the day Tuesday.

“Hopefully here in the next few hours we will be able to have those issues worked out that they are trying to work through,” Price said.

Price said people are meeting with the bill’s Senate sponsor, Sen. Greg Albritton, R-Atmore, about their concerns with the legislation.

“Our goal is the differences that are being worked on, that they will come to an agreement and that agreement will be before the day is out,” Price said.

Tuesday’s stalled meeting is the latest sign of problems with the legislation that passed the House a few weeks ago.

Last week, the Tourism Committee held a meeting that started late and without any advanced public notice of what bills would be on the agenda. The meeting also included a public hearing that was not announced.

The constitutional amendment requires approval by three-fifths of the House and Senate. It cleared that in the House on a 70-32 vote. But Albritton has said the legislation was short of the required 21 votes in the 35-member Senate.

Lawmakers supporting the plan said it would replace a patchwork of Alabama laws with a uniform regulatory framework. It would create an Alabama Gaming Commission that would license up to seven casinos and include a law enforcement division.

The fiscal note prepared by the Legislative Services Agency estimates the net state revenue at up to $492 million from the casinos, up to $379 million from the lottery, and up to $41 million from sports betting. Sports betting could be done at the casinos or on mobile apps.

Opponents of the bill say it would lead to more gambling addiction and the related social problems that hurt families. Some have criticized the legislation because it designates the counties where the casinos would be located and favors current operators of gambling facilities in those counties in what would be the process of bidding for casino licenses.
