It’s official: Maryland lawmakers will be called back to Annapolis next month to weigh an expanded gambling plan.

Gov. Martin O’Malley (D) announced the special session at a Friday morning news conference, flanked by the two top Democratic leaders of the General Assembly.

Lawmakers, in a session starting Aug. 9, will be asked to consider allowing a new Las Vegas-style casino in Prince George’s County and table games, such as black jack and roulette, at Maryland’s five other slots locations.
