People familiar with the conversation, which lasted about 45 minutes, described it as cordial but not productive enough to prompt the announcement in the next couple of days of a special legislative session on expanding gambling.

Neither O’Malley nor Busch commented to reporters after the meeting, which took place in the governor’s office.

O’Malley has said he wants to hold a special session the week of July 9, but a work group he set up recommended against that on Wednesday after members were unable to reach consensus on issues related to a proposed Prince George’s County casino and tax rates on casino operators.

Eight members of the work group — including five O’Malley appointees and three state senators — agreed to a plan that would allow a Prince George's casino and lower tax rates for at least some other venues to compensate for the additional competition.

The plan would also allow Las Vegas-style table games at Maryland’s five existing slots sites.

The three House members on the work group, all appointed by Busch, dissented, saying they would only support a Prince George’s casino if the state’s existing tax rate stayed in place. The dissent was a strong indication that legislation lacked support in the House, prompting the work group’s recommendation against a special session.

On Thursday, both Busch and O’Malley indicated a willingness to keep talking about the issue. After Friday’s meeting, aides to O’Malley indicated he had not ruled out calling a special session but gave no sign that is likely or imminent.

Senate President Thomas V. Mike Miller Jr. (D-Calvert), who did not participate in Friday’s meeting, has been a vocal proponent of a Prince George’s casino.
